Blog Archive MBA News Early Interviews at the Stanford GSB

Blog Archive MBA News Early Interviews at the Stanford GSB Most MBA admissions officers will tell you that it does not matter whether you send your application in early or at the deadline, because they will not read your application until the deadline passes.   Stanford seems to have changed its tune as of late or, at a minimum, articulated a policy that few knew existed before. Stanford will now be reviewing applications and inviting candidates for interviews before its first round deadline passes. Does this mean that others are at an advantage if they get their applications in early? Not really.

Explain Kants Theory of Ethics Essay - 1573 Words

A: Explain Kant’s theory of ethics Kant was born in 1724-1804, he was a German thinker from East Prussia (now Russia), and he spent his whole life in his hometown. Kant wanted to create a logical, stand-alone theory that wasn’t just based on assumptions, he believed in an objective right or wrong that is decided on reason and that we shouldn’t do the right thing just because it’s right and not to fulfil our desires. Can we lead a life following his ideals are there not some situations where a perfect moral decision cannot be made, are all our choices fuelled by personal gain and desire? He has a deontological and absolute approach to ethics, to Kant what makes an action good is when you do your ‘duty’ and that one’s duty is to always†¦show more content†¦Ã¢â‚¬Å"Duties for duties sake† this related to the categorical imperative. Kant then goes on to the 3 maxims, first off to test a moral maxim as it’s a universal law either everyone should follow it or everyone should reject it. The first maxim is ‘Your action should be able to be universalised’ before you act in a certain way, would you like everyone in the same situation to act in the same way. If not, then you are involved in a contradiction it goes against reason, â€Å" so at that principle of action might safely be made of law for the whole world† if you were to take lying through the first maxim its clear it would fail as that would mean everyone would be lying to one another and trust is completely destroyed. The second maxim is ‘Don’ t treat people as a means to an end’ Kant strongly believed that you can never use human beings as a means to an end, to exploit or enslave them. Humans to Kant are all the highest point of creation and so demand a unique treatment. This guarantees that all individuals are afforded the moral principles; therefore no humans can be used for the sake of others, he also explained that we have a duty to develop our own perfection, developing our moral, intellectual and physical capabilities. We also have a duty to seek the happiness of others as long as that is within the law and allows the freedom of others. â€Å"Always recognise that human individually are ends and do not use them as a means to your end† therefore you can’t lie forShow MoreRelatedKantian Ethics vs. Utilitarianism Essay1190 Words   |  5 Pages 1.nbsp;nbsp;nbsp;nbsp;nbsp;Explain Onora O’neil’s argument for preferring Kantian ethics to Utilitarianism. 2.nbsp;nbsp;nbsp;nbsp;nbsp;How would Richard Taylor respond to O’neil’s defense of Kantianism?

10 Interesting Facts About Mercury (Element)

Mercury is a shiny, silvery, liquid metal, sometimes called quicksilver. It is a transition metal with atomic number 80 on the periodic table and an atomic weight of 200.59, and  its element symbol is Hg.  While its an extremely rare element, theres a world of interesting information about mercury. Fast Facts: The Element Mercury Element Name: MercuryElement Symbol: HgAtomic Number: 80Atomic Weight: 200.592Classification: Transition Metal or Post-Transition MetalState of Matter: LiquidName Origin: The symbol Hg comes from the name hydrargyrum, which means water-silver. The name mercury comes from the Roman god Mercury, known for his swiftness.Discovered By: Known before 2000 BCE in China and India Mercury is the only metal that is a liquid at standard temperature and pressure.  The only other liquid element under standard conditions is bromine (a halogen), although  the metals rubidium, cesium, and gallium melt at a temperature just above room temperature.  Mercury has a very high surface tension, so it forms rounded  beads of liquid.Although mercury and all of its compounds are  known to be highly toxic, it was considered therapeutic throughout much of history.The modern element symbol for mercury is Hg, which is the symbol for another name for mercury: hydrargyrum. Hydrargyrum comes from Greek words for water-silver (hydr- means water, argyros means silver).Mercury is a very rare element in the Earths crust. It accounts for only about only 0.08 parts per million (ppm) and is mainly found in the mineral cinnabar, which is mercuric sulfide. Mercuric sulfide is the source  of the red pigment called vermilion.Mercury generally is not allowed on aircraft because it co mbines so readily with aluminum, a metal that is common on aircraft. When mercury forms an amalgam with aluminum, the oxide layer that protects aluminum from oxidizing is disrupted. This causes aluminum to corrode in much the same way as iron rusts.Mercury does not react with most acids.Mercury is a relatively poor conductor of heat. Most metals are excellent thermal conductors.  It is a mild electrical conductor. The freezing point  (-38.8 degrees Celsius) and boiling point (356 degrees Celsius) of mercury are closer together than any other metals.Although mercury usually exhibits a 1 or 2 oxidation state, sometimes it has a 4 oxidation state.  The electron configuration causes mercury to behave somewhat like a noble gas. Like noble gases, mercury forms relatively weak chemical bonds with other elements. It forms amalgams with all of the other metals except iron. This makes iron a good choice to build containers for holding and transporting mercury.The element Mercury is name d for the Roman god Mercury. Mercury is the only element to retain its alchemical name as its modern common name.  The element was known to ancient civilizations, dating back to at least 2000 BCE Vials of pure mercury have been found in Egyptian tombs from the 1500s BCE.Mercury is used in fluorescent lamps, thermometers, float valves, dental amalgams, in medicine, for the production of other chemicals, and to make liquid mirrors. Mercury(II) fulminate is an explosive used as a primer in firearms. The disinfectant mercury compound thimerosal is an organomercury compound found in vaccines, tattoo inks, contact lens solutions, and cosmetics.   Sources Lide, D.R., editor.

Cultural Aspect Of Global Business Samples †MyAssignmenthelp.com

Question: Discuss about the Cultural Aspect Of Global Business. Answer: Introduction This case study is delving with the issues relating to the cultural aspect of global business. Sustainable business practices take into consideration the issues relating to CSR, foreign investment, as well as the advantages of regional integration in respect of the countries within as well as organizations conducting business in that area. The organizations that are trying to start their operations in a foreign nation need to consider the cultural changeability of various areas of the world as well as developing a cultural understanding. Importance of cultural understanding regarding market entry and development When an organization is entering a new market, certain issues in regard to cultural differences might be encountered by the company. Cultural differences that need to be considered by the company entering the new market comprises of factors such as languages, religions, social standards as well as demographics. The significance of cultural understanding regarding the aspect of market entry and development are mentioned as under, The cultural aspect, which might be considered being national or organizational culture, will be providing the company a better understanding for conducting business. It should be noted here that the majority of the daily as well as regular business operations are considered being culturally driven. While entering a new market, an organization should not simply be relying upon its present process of conducting business. The reason for doing so is that the every country is having a set of varied variables that can be regarded as new for an offshore company such as rules and regulations, taxation, different currency, different periods of holiday and so on. The most significant consideration regarding this is the cultural difference (Crowney, 2016). Expansion of business into international territories can take place either via internal growth or mergers and acquisitions. There can occur the aspect of cultural mismatching when an organization will be making decisions in setting up base in a new country since it will be taking time for learning the cultural aspects as well as adopting the countrys traits. When organizations are trying to make an entry into a new market that is having varied cultural aspects, it is required for the organizations entering the new market to have an understanding as well as mapping of the cultural differences for bridging the gap amongst the business units that are performing in multiple cultural aspects. While entering the new market, the knowledge relating to organizational culture is considered essential in respect of managers and should be taken into consideration in the feedback process, intrinsic as well as extrinsic rewards and so on. Organizations that are not having any complete understanding of the cultural aspect of the region that is being targeted for setting up base will often be devising strategies related to marketing that will not be attracting the customers interest and will be facing failure from the very beginning itself. For working effectively in Indonesia there is the need to try reaching an agreement. The country is having an agreement based discussion cultural aspect. One of the constitutional standards is associated with the aspect of making decisions depending upon consultation as well as consensus. This attitude is very much common regarding the business culture in Indonesia. Decisions are made depending upon discussions that are considered being long lasting as well as consultation amongst the business partners. A business solution that might be a considered being a contractual association or any business deal is required meeting the consent of everybody that is having an involvement, since the Indonesian cultural aspect is depending upon a collective principle in which every individual is required providing their consent for having a working solution (Kraidy, 2017). Analysis of the Indonesian culture by using the Hofstede Framework Through the use of the Hofstede Framework, the Indonesian culture needs to be analyzed that will take into consideration the dimensions of Power Distance Index, Individualism, Masculinity, Uncertainty Avoidance Index as well as Long-Term Orientation. Powder Distance Index This dimension is explaining the degree to which the less powerful organizational members as well as institutional members within a country are accepting the fact that there occurs unequal distribution of power. Indonesia will be having a high score regarding this dimension stating that the country is following certain traits such as having dependence on hierarchy, unequal rights amongst the power holders as well as non-power holders, directive leaders, and controls relating to the management. There occurs centralization of the power and managers are counting upon the team members obedience. Staffs are having the expectation of being told what needs to be done and when it should be done. There is the expectation of control and managers are given due respect regarding their position. There occurs indirect communication and negative feedback is not disclosed (Forsgren, 2014). High Power Distance is also stating that the co-workers in Indonesia will be having the expectation of having a clear direction from the manager or senior. Individualism The primary issue that this dimension will be addressing is considered being the level of interdependence that is maintained by the society within its members. In the Individualist societies, it is supposed that people should only be looking after themselves as well as their direct family. In Collectivist societies, individuals are belonging to the in groups that are taking care of them in return of loyalty (Moran, 2014). Indonesia is considered being a Collectivist society, explaining the fact that there is increased affinity for a strong social structure where individuals are having the expectation of conforming to societys ideals as well as the in-groups to which they are a part of. Masculinity A high score i.e. Masculine on this dimension will be indicating that the society gets driven by competition, achievement as well as success, where success gets defined by the one wins or outshines others in their respective field. This is a value system that begins in school and will be continuing all through the organizational phase. A low score i.e. Feminine on this dimension will be stating that the prevailing societal values are to care for others as well as quality of life. From a Feminine societys perspective, quality of life is considered being the sign of being successful and it is not commendable to stand out from the crowd. The primary concern in this respect is what crates motivation from individuals, whether it is the desire for being the best i.e. Masculine or to like what an individual does i.e. Feminine (Storey, 2016). Indonesia is considered having low Masculine regarding this dimension. Within the country, statuses as well as visible symbols relating to success are considered having significance but it is not material profit that will be bringing motivation every time. Most of the time it is the position that is being held by an individual that is considered having more significance to them due to an Indonesian notion known as gengsi that means outward appearances. It is considered being necessary that there is strong maintenance of gengsi so that a different outward appearance gets projected that is having the aim to impress as well as create the impression of status (Brouthers, 2013). Within the Feminine countries, the managers are striving for an agreement, individuals are valuing equality, solidarity as well as quality within their professional lives. There occurs resolving of conflicting situations through the aspect of compromising as well as negotiating. Incentives like free time as well as flexibility are supported. An efficient manager is considered being a supportive one, and there occurs the achievement of decision making via involvement. On the other hand, the lower Masculine countries are displaying the characteristics of Masculine societies but in a lesser quantity. Uncertainty Avoidance This dimension is associated with the manner in which a society is dealing with the fact that the future is always unknown and the degree to which the members of a cultural aspect will be feeling threatened by the circumstances that are considered being ambiguous or not known. Indonesia is having a low preference towards the avoidance of uncertainty, meaning that there is a strong preference within the country regarding the Javanese separation culture relating to the internal self from the external self. One more aspect of this dimension can be associated with Conflict resolution. Direct Communication can be considered as a conflict resolution method that is mostly considered as an intimidating circumstance and one that the Indonesian is not comfortable in (Ambos, 2014). A successful conflict resolution process is associated with the aspect of taking the more familiar path of using a third party mediator that is having numerous beneficial aspects. Long Term Orientation This dimension is describing the ways by which every society is required maintaining certain connections with its individual past while dealing with the challenging aspects associated with the present as well as future. Also, societies are prioritizing these two existential objectives in a different manner. In this regard, it can be stated that countries having a pragmatic cultural approach are encouraging prudence as well as efforts in modern education as a means for preparing for the future. Indonesia is considered having a pragmatic culture and individuals that are in societies having a pragmatic orientation, they are believing that the truth is depending strongly or circumstances, context as well as time (Reiche, 2016). They are showing the capability for the aspect of adapting the traditional aspects in an easy manner for changed circumstances, a strong inclination in respect of saving as well as investing and determination to achieve the outcomes. Impact of CSR issues on the international business activities of an organization In regard to the Corporate Social Responsibility, there are certain issues that are impacting the international business activities of an organization that take into consideration the economic responsibilities, legal responsibilities, ethical responsibilities as well as the philanthropic responsibilities. Economic Responsibilities In respect of the international business activities, it can be stated that the primary responsibility of an organization is associated with its economic responsibilities. This is stating that an organization is required having the primary concern of making profit when setting up business abroad. This is associated with the fact that without making adequate money, staffs will be losing their jobs and the organization will not be able to think about taking care of its social accountabilities in the foreign country. Therefore, prior to an organization having the thought of becoming a better corporate citizen, it primarily requires ensuring that it can become profitable in regard to its international business activities (Armstrong, 2015). Legal Responsibilities The legal responsibilities of an organization are the needs that are placed on it in accord with the law when setting up business in a foreign country. To ensure that the organization is having profitability, it is required ensuring that it will be obeying every law that is prevailing within the foreign country, which is having the most significant accountability, in accord to the corporate social responsibility theory. The legal responsibilities will be ranging from the securities regulations to the labour laws, environmental laws as well as criminal laws in relation to the international business activities (Ferraro, 2017). Ethical Responsibilities After meeting the primary requirements regarding economic as well as legal accountabilities in respect of an organization, there is the need for the organization to concern itself with the ethical responsibilities regarding the international business activities. The ethical responsibilities will be including the process of being environmentally friendly, making the payment of fair wages or refusing to do business with countries that are considered being oppressive (Pudelko, 2014). Philanthropic Responsibilities When an organization will be meeting each of its other responsibilities relating to the international business activities, it will also start to meet the philanthropic responsibilities. These responsibilities are considered moving beyond what is simply necessary or what the organization believes to be correct. They are having the involvement of making an endeavour of benefitting the society within the foreign country (Wild, 2014). Incorporation of risk into market entry strategies using an Adaptation Strategy When an organization will be entering a new market, it is required coping up with the cultural as well as demographic differences in the way it will be handling marketing. The adaptation strategy will be implying the process of changing the different aspects relating to products as well as services to a substantial extent for meeting the requirement of the customers in the global markets by considering their differences. Moreover, while the product adaptation strategy will get involved, there will occur the addressing of the differences relating to particular markets at the stage of product development, accommodating the differences regarding the wants of the customers as well as needs in an efficient way (Stahl, 2015). There are certain disadvantages associated with the adaptation strategy in respect of an organization that are mentioned as under, Increased levels of financial costs can be particularly mentioned as a major drawback relating to the adaptation strategy. Low implementation speed regarding adaptation strategy is considered being another drawback. Adaptation strategy in general, does the elimination of the scopes to benefit from the economies of scale. To learn the conditions regarding the local culture for the integration of this information relating to the components of marketing mix will be considered to be an expensive scheme (Cavusgil, 2014). Description regarding the Association of Southeast Asian Nations (ASEAN) In 1967, there occurred the formation of the Association of Southeast Asian Nations (ASEAN) by Malaysia, Indonesia, Singapore, Thailand and the Philippines towards the promotion of political as well as economic association as well as regional constancy. The ASEAN Community comprises of the three pillars such as the Political-Security Community, Economic Community as well as Socio-Cultural Community. Benefits and drawbacks of regional integration Gains in Trade (Benefits) Trade gains are considered being one of the key advantages in respect of regional integration. This will assist in leading towards the monetary advantages in respect of countries that are having the involvement via more advantages in respect of the countries of origin as well as via cheaper products in respect of the importing nations (Deresky, 2017). Cultural Centralization (Drawbacks) Regional Integration is having a non-economic disadvantage stating that in particular, strong integration will be leading to the loss of distinctive minority cultural aspects within a region. Conclusion To conclude, it can be stated that a discussion has been made regarding the significance of cultural understanding in respect of market entry and development. Then, with the use of the Hofstede Framework, the Indonesian cultural aspect is being analyzed. The CSR issues have been described and explaining in what ways these issues will be impacting the global business activities regarding an organization. Also, a brief description has been provided regarding the Association of Southeast Asian Nations as well as discussing the advantages as well as disadvantages relating to regional integration.

Back In the World

Table of Contents Introduction Story: Adam Smith The Concept of Back in the World Conclusion Works Cited Introduction Back in the world is an expression of a return to an environment which one considers as home and is comfortable with; the person should have been away from home for some time for the phrase to be applicable.Advertising We will write a custom essay sample on Back In the World specifically for you for only $16.05 $11/page Learn More It has been used by Wolf in a very figurative way to illustrate the kind of a confusion that a person faces after spending too much time from the surrounding and society familiar to him or her; such confusion becomes evident after the person comes back to the society and finds out that the place is quite different from they way it he/she left it. The phrase back in the world therefore as used in the book to illustrates the coming back into the society form a different society. Specifically the phrase was coi ned in the story Soldier’s Joy. It is worth noting that this concept of back to the world can be applied to different aspects in the society which may not necessarily involve physical localities. The paper will look into the story of an individual and relates it the author’s concept of back to the world. Story: Adam Smith Adam Smith was an established economist and at the same time, a philosopher in his time. He was born it Edinburgh, Scotland in the first quarter of the eighteenth century. Adam was born to able parents with his mother having been from a wealthy family and his father was a state officer. His father died before he was born. He then joined Glasgow University in the year 1737 where he studied moral philosophy. His level of excellence in the institution earned him a scholarship to Oxford University after his graduation in the year 1740. His time at Oxford was, however, neither pleasant nor successful as he was forced to terminate his scholarship and studie s. His move to stop his studies was based on a number of factors that included misunderstanding between him and the institution as well as his developed beliefs that were not accepted by the institution. The influence that he got from Hume, another philosopher was a factor to the misunderstanding between Adams and the institution since the beliefs by Hume had been denounced by the university. Adams was at the same time not satisfied by the education that he received from the university. These circumstances led to Adam’s move to his hometown where he settled down in the year 1746. In Edinburgh, Adam started to offer lecturers, most of which were public lectures. These lecturers played a significant role in exposing him to the lame light. He was noted by the town’s intellectuals who aided his rise in the intellectual sense. Five years later after leaving the oxford university, Adam was recognized by his former school, Glasgow University that had employed him and even gav e him an award of a professor. Adam was therefore a recognized professor in logic at the age of twenty eight and was to be crowned again, just a year later, by an award in moral philosophy by the same institution (Age 1).Advertising Looking for essay on american literature?

His psychologically closed doors in social concepts saw him stay with his mother instead of moving out to his own house as he grew up. His free time was spent on interactions with fellow intellectuals and leaders in the commercial sector. He thus never offered time for recreational activities or leisure. He then later earned international recognition after the year 1959 following a moral theory that he developed at the time. This led to his change of job that took him to tutoring in different institutions. He was then taken for a c ontinental tour by his employer and met a number of personalities on the fields of economics and philosophy. His interaction with the intellectual class continued as he returned to London earning him an outstanding recognition among intellectuals. This led to his appointment to an intellectual body at the time. After his service as a tutor, Adams settled down again to stay with his mother in his hometown in Scotland. His achievements however continued as he was recognized by his former school, Edinburgh in the year 1777. Then later he served his country as the head of customs department. His other recognized achievements include his philosophical opinions that are identified to have laid the foundation for capitalism. His life came to an end in the year 1790 and was buried in his hometown at Edinburgh. His life was therefore a partial success having been outstanding with regard to professional aspects though his private life failed to realize the same level of success (Age 1). The C oncept of Back in the World The concept of back in the world as presented by Tobias Wolff is particularly evident in the life of Adam Smith. Wolff writing in the collection of Back in the world is a representation of confusion that is experienced by people at a time when they expected change from their domestic set up. In the stories of his collection, Tobias represented the expectations that American soldiers had developed while on foreign missions. There were expectations of relief that they thought was awaiting them back at home only to return and find the normal confusion. This was particularly the case for the veterans returning from Vietnam. This comes out well in the narration of the story Soldier’s Joy where veterans while in the war zone in Vietnam have memories of their homes. It becomes a bit confusing for the soldiers that when they return home they are met with what they never expected. There is a lot of confusion and this discourages the veterans after being bac k in the world. Likewise the life of Adam Smith is similarly characterized by such themes as Wolff’s in the collection of back to the world. His story is characterized with returns to situations that would not be expected of his life. He portrayed less of what would be expected of him at particular times of his returns (Wolff 1).Advertising We will write a custom essay sample on Back In the World specifically for you for only $16.05 $11/page Learn More Adam’s life had a lot of returns, a characteristic of Wolff’s back in the world’s theme of returning to a former position or place. Instances such as Adam’s return to his hometown from Oxford University, his return to London from their continental trip around Europe and his final return to Edinburgh were characteristics of the Wolff’s interest in his particular writing. Adam’s final return from London to Edinburgh and the initial return from oxford however illustrates Wolff’s theme as Adam does not come to a socially developed capacity that is expected of him. In both cases, Adam returns to his mother’s house though he is expected to live independently as a grown up man. Another story that Wolff used to illustrate the concept of back in the home is the story of the lady who was celebrating her birthday. In order to help the lady celebrate her birthday, her friends bring her some cocaine which she is meant to consume to enable her celebrate her birthday. This leads to a bad ending as expected. It is a bit ironical that instead of celebrations being witnessed, the celebrations end in tears. This is a big contrast that is witnessed even in the life of Adam. For instance, it was expected that Adam, after securing a sponsorship, would have a great time at the University of Oxford. In the contrary it has been shown that Adam was not even able to complete his studies at the Oxford University as he had adopted beliefs from Hume which were not accepted by the university and thus he had to drop from college. Conclusion Wolff through a series of stories has shown how situations change and great expectation crumble down. He uses real life events to pass his message across. The story of the Veterans who served in the Vietnam War particularly brings out the concept of back in the home well. Others stories in the collection equally show this concept. There is a great similarity between the life of Adam Smith and the concept of back in the home as brought out by Wolff. The life of Adam Smith is a good depiction of this concept. Works Cited Age.

Solid Waste Management

Solid Waste Management Introduction Solid waste management has significantly gained attention in the present century. With the impacts of globalization, there is a persistent need for transformative mechanisms of solid waste management. Evidently, most nations continue to experience challenges in solid waste management. Particularly, the developing nations are the highly affected (Singh Ramanathan, 2010).Advertising We will write a custom case study sample on Solid Waste Management specifically for you for only $16.05 $11/page Learn More Apart from the available waste management technologies, municipalities face various dilemmas. Specifically, this regards the choosing of either private or public system of solid waste management. Based on an article describing solid waste management in Canada, this paper focuses on this topic. The paper researches and examines the issue of privatization in solid waste management in Canada. Argument on Privatization of Solid Waste Management The a rticle reveals crucial debates on the issue of privatization of solid waste management. Observably, there are present potential arguments on the issue of solid waste management. Generally, the debates are based on public and private management of solid waste (Kumar, 2009). Personally, I encourage the adoption and practice of privatization in solid waste management. This decision is informed by the several advantages of a privatized system of solid waste management. As indicated in the article, privatization of the process leads to the realization of high levels of efficiency. Municipalities are able to integrate of enforce quality management systems due to this approach. Indicatively, the relevant municipality can adopt various transformative measures such as performance contracting. Such initiative would enhance the capacity of private partners to manage and dispose all solid wastes according to the appropriate provisions.  A privatized system of solid waste management enables fu ll compliance by the organizations to various regulatory frameworks. Apart from this, the system allows an easier and flexible manner of conducting compliance monitoring initiatives (McDavid, 1985). Various municipalities around the globe have failed to manage the solid waste in a proper manner. Therefore, privatization enables such municipalities to act as oversight authorities in the disposal and management of these wastes. The approach also minimizes the public expenditures on solid waste management. Thus, more municipal resources are saved and may be utilized in other development projects. Privatization and Improvement of Service Quality Privatization has a significant impact on service quality. The article clearly presents the outcomes on the service quality recorded from a privatized solid waste management system in Canada. It is simple to regulate and contract private firms (Uriarte, 2008). This process is attainable through provision of realistic and competitive service targ ets.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More These targets must be provided or issued to all private firms involved in the management of solid waste. Through engagement of private partners, the solid waste management process becomes more compliant and simple. The municipality only has to provide competitive measures during bidding and p tendering processes. The existence of several players within the private sector increases the rate of competition. Consequently, this situation also leads to the development of high standards for service delivery.  The municipalities are more inclined to offering tenders in consideration of the capacity of individual firms to provide excellent and high quality service. However, it is imperative to note that privatization of solid waste management do not lead to a reduction of cost (Kumar, 2009). Specifically, this is notable in the v arious private entities that are involved in waste management. They incur great expenses due to high competition and demand for strategic and more transformative solid waste management programs. The individual solid waste generators also have to pay expensively for the services of private firms. The Community and Management of Solid Waste There are several factors considered by a community in the adoption of a privatized or public system of solid waste management. Poor road networks make the public to advocate for privatization of the solid waste management (Anand, 2010). However, this decision is likely to be revoked whenever the collection costs for solid wastes increases. Therefore, high collection costs charged by the private waste handlers make the community to shift to public waste management strategies. Increased compactness of solid waste increases the likelihood of the community to seek for a privatized system of waste management. Highly compacted solid waste might be diffi cult to transport, dispose or manage at household or community levels. Effective transportation is a crucial component of solid waste management. However, most solid wastes might be difficult to transport. This depends on several factors including the nature of waste, availability of adequate and improved road network and other required equipment. Regional proximity determines whether the community would opt for a privatized or public solid waste management practices. Facilities located far away from the residence areas of the community might increase the chances for a privatized waste management strategy (Uriarte, 2008). It is evident that the community plays a fundamental role in the determination and dictation of market options in solid waste management.Advertising We will write a custom case study sample on Solid Waste Management specifically for you for only $16.05 $11/page Learn More Some of their practices do not promote competitive bidding markets. Most private organizations involved in the management of solid waste are confronted by serious challenges. Analytically, these challenges emerge from the community factors. References Anand, S.

Describe recruitment and selection process among U.S police Essay

Describe recruitment and selection process among U.S police departments during the last half of the nineteenth centry (i.e., the first fifty years of policing) - Essay Example Police departments were organised as per political affiliations. Police in these early days was organised under police chiefs. These police chiefs were appointed by political bosses. These political bosses ensured that the police chiefs and the subsequent police mechanisms remained subservient to them. Corruption was the order of the day in order to satisfy the political bosses’ aims and objectives. The common man was harassed by utilising the police framework so as to secure political domination. The presence of political machines meant that political bosses were on the lookout for ways to offset the balance of power in their favour. Cops were recruited by political machines in an effort to encourage citizens to vote for the â€Å"right† political candidate. Often police brutality ensured that the wishes of the political bosses were carried out in letter and spirit. Police was used to exert political influence by intimidating, intruding and pressurising ordinary people and businesses. Corruption was reduced to a complete system. Payoffs on massive scales ensured that the policemen remained loyal to a political side. Crime was organised as robberies, extortions, gambling and other illegal activities were carried out systematically. Another tendency of this era was earmarking police personnel as per their political affiliations. Often as political machines waned, so did the police framework supporting them. Each political machine ensured that â€Å"their cops† were placed in active duty to protect their interests. These early tendencies for police brutality and corruption were in line with the sociological facets of the time. People were not politically organised in coherent regimes to ensure that police corruption could be settled through political resolve. Moreover, the presence of corrupt politicians backed by clandestine businesses ensured that the police framework remained in line with their demands and

Book review - Essay Example Amongst his collection of short stories, Blood and Tears stands out from amongst the rest because of its literary values and the ideas presented within. In the introduction to these stories, Ali (1984) compares Mas to other Malaysian writers and says that, â€Å"The few short stories which he has contributed have greater literary value than the more prolific output of many other writers. For this reason alone Keris has earned a special place and is to be regarded as the leading figure in the new literature (Ali, 1984, Pg. 8)†. If anything at all, Blood and Tears establishes that quality is indeed more important than quantity. While examining the stories, it becomes clear to us that the historical and cultural influences of the Malaysian past figure prominently in the works of Mas. Like many other nations in south Asia, Malaysia has a history of colonization as well as rule by foreigners on local soil and the after affects of colonization remain with the people even after many decades have passed. The struggle between the Japanese and the British over Malaysia during the Second World War gave birth to the country but also create social and cultural dichotomies which still linger as a part of the social structure of the country. Mas was certainly an influential writer and had a close group of fellow writers that sought to bring about changes in Malaysian society by creating awareness through literature. Speaking about these likeminded writers as well as himself as a writer, Mas says that: â€Å"We criticized societal backwardness and those whom we regard as the instruments responsible for the birth of such backwardness. We criticized colonialism and its instruments, that is, the elite class, those whose consciousness have been frozen by the influence of feudalism and myths, and superstition that has been enmeshed with religion (Wikipedia, 2007, Pg. 1)†. Such leanings

Everything about eating. In addition, there are lots of new beverage brand in the world. If Negative news led to lose market, company would very hard to get market back

The Cold War Essay -- American History Papers

The Cold War When World War II in Europe finally came to an end on May 7, 1945, a new war was just beginning. The Cold War: denoting the open yet restricted rivalry that developed between the United States and the Soviet Union and their respective allies, a war fought on political, economic, and propaganda fronts, with limited recourse to weapons, largely because of fear of a nuclear holocaust.1 This term, The Cold War, was first used by presidential advisor Bernard Baruch during a congressional debate in 1947. Intelligence operations dominating this war have been conducted by the Soviet State Security Service (KGB) and the Central Intelligence Agency (CIA), representing the two power blocs, East and West respectively, that arose from the aftermath of World War II. Both have conducted a variety of operations from large scale military intervention and subversion to covert spying and surveillance missions. They have known success and failure. The Bay of Pigs debacle was soon followed by Kennedy's ft handling of the Cuban missile crisis. The decisions he made were helped immeasurably by intelligence gathered from reconnaissance photos of the high altitude plane U-2. In understanding these agencies today I will show you how these agencies came about, discuss past and present operations, and talk about some of their tools of the trade. Origin of the CIA and KGB The CIA was a direct result of American intelligence operations during World War II. President Franklin D. Roosevelt recognized the need to coordinate intelligence to protect the interests of the United States. In 1941, he appointed William J. Donovan to the head of the Office of Strategic Services (OSS) with headquarters in London. Fo... ...or the enemy and ally alike so as to be able to understand their capabilities and shortcomings without intelligence agencies. The CIA and KGB by themselves cannot assure peace. With the knowledge supplied by each to its leaders, intelligent decisions can be made in the world's best interest. Moreover, the status quo and power base remains relatively stable with the East and West on opposing sides. There can never be true and utterly complete peace, these organizations will continue to exist contrary ignorant ideals of the public for peaceful coexistence.

Solder Joint In Electronic Engineering Essay

Electronic makers throughout the universe have a long history of utilizing lead-based solders. These solders have proven to be cost effectual and high reliable, and are solidly integrated into fabricating methods and procedures. Driven by statute law chiefly in the European Union i.e. WEE, RoHS, EEE Directives, makers are concrete the manner for taking lead solder from all electronics assemblies. However, the credence of nonleaded solder posses many draw dorsums. Conversion to RoHS ( Restriction of Hazardous Substance ) compliant parts must include the full merchandise development and fabrication procedure. To electronics makers, one of the most of import facets in the procedure is guaranting the nonleaded solder articulation dependability is equal to or greater than that of their current leaded solder composings. Manufacturers are working independently to formalize dependability for their nonleaded electronic constituents and systems. Likewise, industry organisations and other research workers have developed proof plans that attempt to understand failure mechanism associated with nonleaded merchandises, generate dependability acceleration theoretical accounts, and predict the dependability of nonleaded solder articulations. Several theoretical accounts of lead free solder articulation dependability non mature plenty yet to enable alone demand of aerospace and military intent. Several factors affect solder articulation dependability, i.e. portion geometry, solder drosss, and external environmental emphasiss. Rapid thermic cycling has been an effectual environmental stimulation capable of bring oning weariness on solder articulations, peculiarly with stuffs holding mismatched thermic enlargement coefficients. Mechanically induced quiver is another external emphasis that efficaciously evaluates solder joint dependability. Thermal cycling can bring forth high supplanting emphasiss at low rhythm frequences, whereas mechanical quiver can supply low supplanting emphasiss at high frequences and high rhythm counts. A peculiar type of trial equipment and methodological analysis capable of using a combination of rapid thermic cycling and quiver is Highly Accelerated Life Testing ( HALT ) . Circuit boards range from simple individual moulded plastic boards with Cu music directors on one or both sides to multilayer boards with Cu music directors, each bed being separated by a insulator and interconnected by metal music directors. Minimum line breadth and spacing between lines is less than 100 A µm. The board typically is made from a composite such as an epoxy with superimposed sheets of woven fiberglass. The dielectric stuff between beds of music directors is normally a polymer, for illustration polyimide. To keep solder ability, the exposed Cu may be coated with an inhibitor such as benzotriazole or with a solder greatcoat. Components are attached to the board with solder or metal-filled conductive adhesives. Fully assembled boards may be farther protected against wet, taint, and mechanical harm by a screen coat. ( Steinberg D,1988 )1.2 SOLDER JOINT RELIABILITY AND FAILURESolder articulations widely used in the electronic packaging industry to bring forth good electri cal, thermic, and mechanical connexions between the bundle and the printed circuit board. Twenty per centums of the mechanical failure in airborne and mechanization electronic cause by quiver and daze. Design appropriate step to guarantee the survival equipment in the daze and quiver environment is necessary to make so. Staying 80 per centum of mechanical failure related to thermic emphasiss ensuing from high thermic gradients, coefficient of thermic enlargement and high coefficient of snap. Solder joint failure occurs in several grounds: Poor design of the solder articulation A bad solder articulation intervention Solder stuff Excessive emphasis applied to solder articulations. In general, nevertheless, the solder articulation failures are merely graded harmonizing to the nature of emphasis that have caused. Most joint failure falls into three major classs: Fatigue failure due to cyclic emphasis application Due to the execution of a long term or lasting burden The emphasis is due to overloading in the short term Reflow profile besides has a important function on solder articulation reliablity. Because It besides has a high influence micro construction of the solder articulation. Vibration failure of solder articulations is assessed for dependability utilizing high accelerated life trial, which is represented by a GRMS- clip curve. For surface saddle horse microelectronic constituents, an estimate of printed circuit board ( PCB ) theoretical account analysis can be made by presuming PCB as a bare unpeopled thin home base because the addition in stiffness of PCB due to the climb of the constituents is about offset by the addition in entire mass of the populated PCB. However, this estimation can direct to mistakes in natural frequence computation for different bundle profiles, for flip-chip-on-board ( FCOB ) and plastic-ball-grid-array ( PBGA ) assemblies. When the constituent has little profile, the estimate of PCB assembly as a bare PCB can supply acceptable average analysis consequences because the stiffness and mass part of little constituent to PCB assembly is non considerable. In this trial, changing GRMS-level random quiver trial for PCB assemblies were conducted. In order to cipher the dependability of PCB assembly, it is necessary to carry on the dynamic analysis.1.3 PROJECT PURPOSEIn this modern universe due to the causes of wellness and environmental issues the electronic fabrication industries confronting a challenging job of necessity to bring forth dependable solder merchandises in really high denseness with really low cost. Solder articulations are really of import to the dependability of Printed Circuit Boards ( PCB ) . This is a 1 of the taking factor in transmittal of electrical and thermic connexions. In instance of every PCB even a smaller solder articulations are really of import. So this undertaking investigates the Effect of quiver on solder articulation dependability in electronics assembly applications. Solder articulation of an electronic assembly is really of import measuring because of this theoretical account based survey might assist applied scientists efficaciously better the PCB mechanical design and therefore better dependability of electronics attached to the PCB by sing practical uncertainnesss and inauspicious quiver environments. This experiment attempted to research the usage of HALT to measure the dependability of solder articulations. For this trial, samples of PCB ‘s arranged and tested on an Environmental testing chamber. The trial program included a response where, as samples become displaced from the printed circuit board ( PCB ) , . In add-on, a solder joint life distribution would be bring forthing depicting comparative public presentation between Sn95.5/Ag4.0/Cu0.5 vs. Sn42Bi57Ag1 solder paste. The consequence of this trial did non bring forth the sequence of failures necessary to be after the life informations ; nevertheless the procedure of proving revealed near by into the application of HALT as a technique to contrast the public presentation of PCB soldered constituents. ( Steinberg D,1988 ) The overall research methodological analysis that has been followed during the undertaking is illustrated in Figure 1.1. There are six distinguishable stairss: Literature Survey, Project Planning, Design of Experiments, Experimental work, Analysis of consequence and Conclusion, and Documentation and Presentation. Literature Survey Design of Experiments Undertaking planning Experimental Work Analysis of Results and Conclusion Documentation and Presentation Figure 1.1: Undertaking MethodologyChapter 2LITERATURE REVIEW2.1 SINUSOIDAL VIBRATION TESTINGDynamic warps of stuffs caused by quiver can do jobs and malfunctions including failed electrical constituents, deformed seals, optical and mechanical misalignment, cracked or broken constructions, inordinate electrical noise, electrical trunkss, chafed wiring. Because sine quiver represent largely a certain cardinal frequence and the harmonics of that cardinal, in its pure province, this type of quiver is generated by a limited important figure of beginnings. Expressed as amplitude versus frequence, sine quiver is the type of quiver generated in the field by beginnings such as engine rotational velocities, propellor and turbine blade transition frequences, rotor blade transition and launch vehicles. While much of â€Å" existent universe † quiver is random, sine quiver proving accomplishes several of import ends in merchandise ability and proving. Much stuff and completed merchandise was modelled on some type of sine quiver signature. A sine expanse of frequences will reason whether the premises were right and if the divergences are considerable plenty to do design alterations. In other words, expanse will set up if the imagined frequence has been met and/or discovers the trial point cardinal frequence. Similarly, a expanse will assist place the trial capable resonance frequences, which may be the points at which the point experiences peculiarly nerve-racking warps. Some of the undermentioned trials include fixed frequence at higher degrees of the commanding variable ( displacement, speed, acceleration ) , and random quiver. Another typical sinusoidal quiver trial, sine explosion such as the teardrop, goes quickly to top out pulsation and so decays at lower rate ( to forestall harm to the unit ) . The burst trial puts a maximal burden into an object at a rapid rate and peculiarly emphasiss articulations and seams to place craft and design issues.2.2 RANDOM VIBRATION TESTINGThe genuineness of random quivers an effectual tool of testing craft defects came about during fabrication. Up until that limited hertz sine was applied during dependability proving. Pure sinusoidal quiver is composed of a individual frequence at any given clip. Comparisons trials revealed that to be the effectivity of random quiver. The trial point will hold to be subjected to many sine frequences over a longer period of clip, and may by happenstance weariness the trial point. Random quivers undercover defect faster. Another fluctuation would be a swept sine on random trial. In random quiver nevertheless, all frequences happening at the same time. Because of this, random quiver analysis normally performed over a big scope of frequences, say from 20Hz to 2000Hz. Research workers are non looking at a specific frequence, specific minute in clip or specific anything else ; They are statistically looking at a construction response to a given random quiver environment. Decidedly be cognizant about any natural frequences that cause a big random response at any open frequence degree, but largely all the experiments taking the overall response of the construction. Random quiver analysis looks at random accelerations or forces over a scope of frequences, which we call the frequence sphere. ( These random inputs are merely sustained over a period of clip, but are non time-dependent ; i.e. , the longer the period of clip, the better the statistical sampling in the frequence sphere. ) The scope of frequences is called a spectrum. Therefore, this is called by Spectral Density. Normally, if accelerations consider in trial, for that Acceleration Spectral Density ( ASD ) have to utilize.2.3 SINE ON RANDOM VIBRATION TESTINGVibration sine on random testing is executing by superposing a sine moving ridge on top of a random environment. A sine on random quiver trial replaces the combined environment of a spinning chopper blade with its distinguishable resonant degrees and the remainder of the aircraft which generates random engine and aerodynamic induced quiver. Gunfire on board an aircraft causes sine quiver while the remainder of the aircraft generates random excitements. These types of trials are doubling quiver Characterized by dominant extremums ( sinusoids ) superimposed on a broadband background. 2.4 Real WORLD SIMULATION. Most quiver in existent universe is random for illustration a vehicle traveling over route feels random quiver from the route abnormalities. Land launched projectile vehicles exposed to non stationary quiver during its flight, the motor ignites the projectile travel through the ambiance, the motor burn terminals and so forth even in flying when subjected to turbulent air flow, undergoes random quiver. Random quiver is composed of battalion of continues spectrum of frequences. Movement varies indiscriminately with clip. It can be accessible in the sphere by a power spectral denseness map [ G2/Hz ] .2.5 HIGHLY-ACCELERATED LIFE TESTING ( HALT )HALT involve quiver proving in all three axes with a random manner of frequences. at last, HALT proving can include the real-time cycling of multiple environmental variables, for illustration, temperature cycling plus quiver testing. This multi-variable proving attack provides a closer appraisal of real-world operating environments. Unlike usual testing, the end of HALT proving is to interrupt the specimen. When the merchandise fails, the weakest point is recognized, so applied scientists know closely what demands to be done to develop merchandise quality. After a merchandise has failed, the weak constituents are upgrade or toughened. The revised specimen is so subjected to an extra unit of ammunition of HALT proving, with the scope of temperat ure, quiver, or floor further increased, so the merchandise fails once more. This identify the following weakest point. By traveling through several proving like this, the merchandise can be made rather strong. With This familiar attack, merely the weak musca volitanss are identified for betterment. This type of proving supply so much information about the assembly and public presentation of a merchandise, that it can be rather supportive for newer applied scientists assigned to a merchandise which they are non wholly familiar. HALT proving must be performed during the design period of a merchandise to build the basic design is dependable. But it is indispensable to observe that the units being tested are likely to be hand-made technology paradigm. At suggestion, we have found that HALT proving should besides be performed on existent industry units, to guarantee that the passage from technology design to production design has non resulted in a loss of merchandise quality or hardiness. Some applied scientists may see this attack as scientifically sensible, but economically impractical. though, the cost of HALT proving is much a lesser sum of than the cost of field failures.2.6 HIGHLY-ACCELERATED STRESS SCREENING ( HASS )HASS testing is an ongoing showing trial, performed on usual production units. Here, the thought is non to damage the merchandise, but instead to verify that existent industry units continue to run decently when subjected to the cycling of ecological factors used during the HASS trial. The bounds used in HASS proving are based on a skilled probe of the HALT proving parametric quantities. The importance of HASS proving can be suited when 1 considers today ‘s typical production scenario. Natural stuffs are purchased from a seller who uses stuffs purchased from other sellers. Components and sub-assemblies are obtained from makers all over the universe. The finishing gathering of the merchandise is performed by a subcontractor. This manner that the quality of the concluding merchandise is a function of the quality of all the constituents, stuffs, and procedures which are a portion of that concluding merchandise. These constituents, stuffs, and procedures c an and make alter over clip, in that manner impacting the worth and dependability of the concluding merchandise. The best manner to guarantee that fiction units continue to run into dependability aims is through HASS testing.2.7 RELIABILITYDependability is definite as the chance that a device will execute its required map under stated conditions for a exact period of clip. predict with some grade of Confidence is really dependent on right specifying a figure of parametric quantities. For case, taking the sharing that matches the information is of primary importance. If a right distribution is non chosen, the consequences will non be dependable. The confidence, which depends on the sample size, must be adequate to do right determinations. Individual element failure rates must be based on a big adequate population and of import to truly reflect present twenty-four hours normal uses. There are experimental considerations, such as influential the incline of the failure rate and cipherin g the activation power, every bit good as ecological factors, such as temperature, humidness, and quiver. eventually, there are electrical stressors such as electromotive force and current. Dependability technology can be slightly conceptual in that it involves much statistics ; yet it is technology in its most reasonable signifier. Will the design execute its proposed mission? Product dependability is seen as a grounds to the stamina of the design every bit good as the unity of the category and fabricating committednesss of an societies. One of the rudimentss of understanding a merchandise ‘s dependability requires an apprehension of the estimation of the failure rate. The conventional method of finding a merchandise ‘s failure rate is through the usage of accelerated quiver runing life trials perform on a sample of Devicess. The failure rate obtained on the life trial sample is so extrapolated to end-use fortunes by agencies of prearranged numerical theoretical accounts to give an appraisal of the failure rate in the field application. even though there are many other emphasis methods engaged by electronic assembly makers to to the full separate a merchandise ‘s dependability, the informations generated from operational life trial sampling is the major method used by the production for gauging the failure rate of a electronic assembly in field service.Failure Rate ( I » )Measure of failure per unit of clip. The utile life failure rate is based on the exponential life distribution. The failure rate typically decreases somewhat over early life, so stabilizes until wear-out which shows an increasing failure rate. This should happen beyond utile life.Failure In Time ( FIT )Measure of failure rate in 109 device hours ; e. g. 1 FIT = 1 failure in 109 device hours.Entire Device Hours ( TDH )Th e summing up of the figure of units in operation multiplied by the clip of operation.Average Time between failures ( MTBF )Dependability is quantified as MTBF ( Average Time Between Failures ) for repairable merchandise and MTTF ( Average Time To Failure ) for non-repairable merchandise. A right apprehension of MTBF is of import. A power supply with an MTBF of 40,000 hours does non intend that the N = Number of units under trial. If the MTBF is known, one can cipher the failure rate as the opposite of the MTBF. The expression for ( I » ) is: where R is the figure of failures. Once a MTBF is calculated, chance can deduce from following equation:R ( T ) = e-t/MTBFConfidence Level or Limit ( CL )Probability degree at which population failure rate estimations are derived from sample life trial. The upper assurance degree interval is used.Acceleration Factor ( AF )A changeless derived from experimental informations which relates the times to failure at two different emphasiss. The AF allows extrapolation of failure rates from accelerated trial conditions to utilize conditions. Since dependability informations can be accumulated from a figure of different life trials with several different failure mechanisms, a comprehensive failure rate is desired. The failure rate computation can be complicated if there are more than one failure mechanisms in a life trial, since the failure mechanisms are thermally activated at different rates. Equation 1 histories for these conditions and includes a statistical factor to obtain the assurance degree for the resulting failure rate.The Bathtub CurveThe life of a population of units can be divided into three distinguishable periods. Figure 1 shows the dependability â€Å" bathtub curve † which theoretical accounts the cradle to sculpt instantaneous failure rates vs. clip. If we follow the incline from the start to where it begins to flatten out this can be considered the first period. The first period is characterized by a decreasing failure rate. It is what occurs during the early life of a population of units. The weaker units die off go forthing a population that is more strict. This first period is besides called baby mortality period. The following period is the level part of the graph. It is called the normal life. Failures occur more in a random sequence during this clip. It is hard to foretell which failure manner will attest, but the rate of failures is predictable. Notice the changeless incline. The 3rd period begins at the point where the incline begins to increase and extends to the terminal of the graph. This is what happens when units become old and get down to fail at an increasing rate.Figure 2.1 bath bath curveReliability Predictions MethodsA batch of clip has been spent on developing processs for gauging dependability of electronic equipment. There are by and large two classs: ( 1 ) anticipations based on single failure rates, and ( 2 ) demonstrated dependability based on operation of equipment over clip. Prediction methods are based on constituent informations from a assortment of beginnings: failure analysis, life trial informations, and device natural philosophies. For some computations ( e.g. military application ) MIL-HDBK-217 is used, which is considered to be the standard dependability anticipation method. A simple failure rate computation based on a individual life trial would follow equation 1. I »iˆ = failure rate. TDH = Total Device Hours = Number of units x hours under emphasis. AF = Acceleration factor, Since dependability informations can be accumulated from a figure of different life trials with several different failure mechanisms, a comprehensive failure rate is desired. The failure rate computation can be complicated if there are more than one failure mechanisms in a life trial, since the failure mechanisms are thermally activated at different rates. Equation 1 histories for these conditions and includes a statistical factor to obtain the assurance degree for the resulting failure rate where, I » = failure rate in FITs ( Number fails in 109 device hours ) I? = Number of distinguishable possible failure mechanisms K = Number of life trials being combined eleven = Number of failures for a given failure mechanism I = 1, 2, †¦ I? TDHj = Total device hours of trial clip for life trial J, J = 1, 2, †¦ K AFij = Acceleration factor for appropriate failure mechanism, I = 1, 2, †¦ K M = I §2 ( I ± , 2r +2 ) / 2 where, I §2 = qi square factor for 2r + 2 grades of freedom R = entire figure of failures ( I? xi ) I ± = hazard associated with CL between 0 and 1.2.2 SOLDER PASTERole Of Solder Paste In ReflowingSolder paste is a combination mixture of a flux composing and a extremely grinded, powdered solder metal metal that is usually used in the electronics industry to soldering procedures. And besides it is call as a attachment medium between the device interconnectedness characteristics and the PCB itself. The constituents of a solder paste are specially designed for first-class printing and reflow features. In normal instance of the surface saddle horse soldering procedure involves puting the substrate and a little sum of solder paste in a printed circuit board. After that the system will be heated until the solder reflows, forms an electrical connexion between the solder tablet and the electrical contact of electronics portion. After this reflow finished it forms both an electrical and mechanical connexion between the electronics constituents and the printed circuit board.Selection Criteria Of A Solder PasteChoice of a solder paste is really of import factor for reflowing procedure, dependability & A ; its quality. The undermentioned factors are considerable for a good solder paste [ 6 ] . The size of the solder metal atoms which are in the solder paste The inclination to organize nothingnesss The belongingss of the flux medium of the solder paste Alpha atom emanation rate The design of the stencil to be used for publishing Thermal belongingss of the solder paste Electrical belongingss of the solder pasteChapter 03MATERIALS AND EXPERIMENT METHODOLOGY3.1SOLDER PasteThe inside informations of solder paste used in the experiment are given in the undermentioned tabular arrayPCB noAlloy1 & A ; 2 Sn95.5Ag4Cu0.5 3 & A ; 4 Sn42Bi57Ag1 Table 3.1. types of solder paste used in experiment For this undertaking all above solder paste should be in a container with appropriate labelling and designation on it to separate it from the Tin – lead solder paste. The solder paste should be stored in a icebox between 35 – 45F. and should be allowed to come room temperature for minimal four hours before making the solder paste printing. Once it has finished the utilizing solder paste must replace to the icebox since it can non be at room temperature over 24 hours. The self life of the lead free solder pastes may be cut downing from the typical six month. The above guidelines are purely followed in this undertaking. Because it is non merely for warrant the quality of solder paste but besides a good manner to cut down the mistakes that may impact the concluding consequences of the undertaking.3.2 SOLDER PASTE PrintingImportant of Solder Paste PrintingSurface mount engineering ( SMT ) is used extensively in the electronics industry. Surface saddle horse constituents are potentially more dependable merchandises can be designed and manufactured utilizing the SMT. The solder paste stencil publishing procedure is really critical and of import measure in the surface saddle horse manufacting procedure. Most of all the bonding defects are due to jobs covering with the showing procedure. Stencil printing procedures have major cautiousnesss in operation and put up stairss. When we are supervising these factors carefully we can minimise the defects. The chief intent of publishing solder paste on PCB is to provide solder metal to solder joint to rectify sum. That merely publish must be aligned right and can acquire a perfect constituent arrangement.Printing Procedure ParametersSome of the undermentioned parametric quantities are really of import to publishing procedure. Stencil Stencils are utilizing for the solder paste slip easy off the aperture edges and thereby secures a unvarying print. For this procedure we utilizing electro formed stencils. Because of these stencils have really shape border and somewhat conelike. By and large a stencil is mading from cuppa or Ni. ENVIRONMENTAL Dust and soil from the air that will make the PCBs and stencils can be defects hapless wet ability in the reflow bonding procedure. So PCBs should be stored in certain bundles and cleaned before usage. SOLDER PASTE Solder paste characterise must be controlled to accomplish a maximal production consequences. Some of the factors are given below [ 12 ] . Percentage of metal Viscosity Slump Solder balls Flux activity working life and shelf lifeSolder Paste Printing Equipment and ProcessStencil printing parametric quantities are really of import factors in publishing procedures to accomplish a best output. The undermentioned parametric quantities must be proctors and controlled in a printing procedure. Squeegee force per unit area = 8kg Squeegee speed = 20 mm/s Separation speed = 100 % Printing spread = 0.0 millimeter These factors and bound can be adjust for our undertaking intent Figure 3.1 DEK 260 stencil printing machine The DEK 260 stencil printing machine is used to publish solder paste on the circuit board. This DEK 260 stencil printing machine has two chief maps. Registers the place of the merchandise screen with in the print caput Positioning the circuit board below the stencil, to cook for the print rhythm. The boards to be print are supported on magnetic tooling and held by vacuity caps arranged on the home base to vouch the board steady during the printing on to the board. The first measure of the experiment is to make the solder paste publishing on to the board.Figure 3.2 Stencil printing by manusIn this undertaking unable to acquire metal stencil, so circuit boards are printed by manus, below process followed to publish PCB Put weights onto the stencil to repair it turn over the squeegee over the stencil solder paste presses through the aperture onto PCB separate stencil Two circuit boards are printed with solder paste for each solder paste types. Wholly 4 circuit boards printed.Pick and PlaceComponent of PCB placed by choice and topographic point machine ( APS Gold-Place L20 ) . robotic weaponries are used to put surface-mount devices onto PCB. Pick and topographic point process as follow. pneumatic suction noses taken by caput of arm, so moved to feeder where the constituent is loaded. The suction nozzele picks it up utilizing vacuity, and moves to the arrangement location so centers the constituent with focus oning fingers. After justified aligned point, it places the constituent onto solder paste.Figure 3.3 APS Gold-Place L203.3 SOLDER PASTE REFLOWPROCESS & A ; PROFILEFigure 3.4 reflow ovenReflow procedure is really of import to accomplish a good dependable solder articulation. Novastar 2000 HT convectional reflow oven is used in research lab for the probe. When making the reflow procedure with lead free solder paste it has to be performed at a m inimal peak temperature of 150.It is by and large accepted that lead free solders requires a higher reflow temperature up to 230 – 240.reflow oven has six warming zones and chilling zone. ( Wu J.2000 ) Reflow profile will be impacting the dependability of a solder articulation. Because it is a major factor that influence the formation of the intermettallic beds in a solder articulation. Intermettalic bed is a critical portion of a solder articulation. An intermettalic bond thickness should be thin. Therefore a good reflow profile must bring forth solder bumps with a thin intermetallic layer.. ( Zhang RR.2001 )PREHEAT ZONEIn this zone indicates how the temperature is altering fast on the printed circuit board. The ramp-up rate is normally between 1-3 per second. If this rate exceeds there will be harm to constituents from thermic daze. Merely In this preheat zone the solder paste begins to vaporize. So if the rise rate is excessively low the vaporization of flux is non uncomplete. This will impact the quality of the solder articulation.THERMAL SOAK ZONEIt is besides called the flux activation zone. In this thermic soak zone it will take 60-120 seconds for remotion of solder paste an d activation of fluxes. Solder splatter and balling will be go on if the temperature is excessively high or excessively low. End of this thermic daze zone a thermic equilibrium will finish the full circuit board.REFLOW ZONEIn this reflow zone merely the maximal temperature will be reached. In this zone we have to see about the peak temperature that is the maximal allowable temperature of full procedure. It is really of import to supervise this maximal temperature exceeds the peak temperature in this zone. It may do harm to the internal dies of SMT constituents and a block to the growing of intermetalic bonds. we have to see the profile clip besides. If clip exceeds than the industries specification it besides affect the circuit board ‘s quality.Cooling ZoneIn the reflow procedure the last zone is chilling zone. A proper chilling inhabits extra intermetallic formation or thermic daze to the constituents. By and large the chilling zone temperature scope is 30 – 100. In this undertaking, the undermentioned temperature profiles were selected. This temperature profile is stranded reflow profile for lead free bonding. Zone 1 220 Zone 2 180 Zone 3 170 Zone 4 190 Zone5 233 Zone 6 233 Wholly 4 circuit boards were printed. Choosing of good reflow profile was non involves any defects or amendss in the printed circuit board.Figure 3.5 Reflow profileFigure 3.6 printed circuit board after reflowSET UP EVENT DETECTORFigure 3.7 Event sensorThe constructed PCB ‘s were connected with event sensor by thread informations overseas telegram. Ribbon overseas telegram addressed harmonizing to `Analysis tech STD series event sensors manual ‘ . pins 1 to 32 map as beginning terminus and pins 33 to 37 map as land terminus.Figure 3.8 Ribbon overseas telegram pin referenceTo obtain closed cringle circuit to supervise the behavior of PCB constituents, PCB boards 1, 2, 3 and 4 connected to impart 1,2,33 and 34 severally.Ribbon overseas telegramAfter connected thread overseas telegram with event sensor and environment chamber, channels are assigned in â€Å" WIN DATA LOG † package which supplied with event sensor. For this trial following scenes define for informations acquisition.Figure 3.9 set up trial informations in event sensor3.5 INVESTICATING RELIABILITY OF SOLDER JOINT UNDER VIBRATION CHAMERFigure 3.10 Design Environmental FS800-70SVIn this survey, PCB ‘s were used in Variable Frequency Vibration Test to analyze the dynamic response of PCB assembly subjected to random quiver burden. The PCB specimens were tested at different acceleration degrees to measure the solder articulation dependability subjected changing G-level quiver tonss ( G is the gravitative acceleration ) , severally. Vibration trials were accomplished by utilizing an electro dynamic Shaker ( Design Environmental FS800-70SV ) and event sensor. One accelerometer was used to find the dynamic response of the specimen, Daisy concatenation cringles were monitored at the same time by an Event Detector during quiver trial. Any opposition alteration transcending a preset threshold with minimal continuance of 200ns can be d etected by the Event Detector. When a cleft is initiated in the solder articulation during the quiver trial, the opposition will increase. The failure standards recommended by IPC – 785 criterion is defined as daisy concatenation opposition by thermic or mechanical transients or perturbations in the signifier of short continuance ( ~ 1 A µsec ) high opposition spikes ( & gt ; 300 a„ ¦ ) . During thermic alterations the solder articulations are capable to shear, non tensile, lading ; hence, fracture surfaces of fractured solder articulations slide relative to each other bring forthing the characteristic short continuance intermittent. Therefore, in this context, the practical definition of solder joint failure is the break of electrical continuity ( & gt ; 300 ohms ) for periods greater than 1 microsecond. Figure 3.11 PCB ‘s was mounted inside the Environment chamber in this mode. Figure 3.12 Above tabular array exemplifying trial program.Figure 3.13 Trial programFigure 3.14 graphs obtained from chamberChapter 4ConsequencePCB board Failure rate ( % ) Operation clip ( hours ) Dependability 1 24.0 5 0 2 63.0 13.04 0 3 1.6 0.3305 0.5893 4 2.5 0.5083 0.2806Table 4.1 dependability of solder pasteThe proving began with 1 GRMS. The intent of this to observe any gross issues in solder articulations, every bit good as with the informations acquisition system. No failures were detected at beginning, nevertheless, after 1.5GRMS an review revealed that both PCBs 3 and 4 were failed. Following, quiver degrees were stepped bit by bit to 6GRMS increases over the period of five hours PCB 1 got failed, In 13.04 hr ‘s period the chamber reached degree of about 14GRMS, staying PCB besides got failed. However, the failure mechanism was attributed to a quiver moving on the solder connexion particular to these parts and was straight related to thermic mistakes. Failure rate Time elapsed Above graph illustrating failure rate vs. Time elapsed for Sn42Bi57Ag1 Failure rate Time elapsed Above graph illustrating failure rate vs. Time elapsed for Sn95.5Ag4Cu0.5Chapter 5RESULT ANALYSISFrom dependability analysis sample 3 has maximum dependability and sample 2 has minimum dependability. Each sample was subjected to nominal supply current and opposition value in conformity with the design and public presentation specification. Respective trial samples continued to vibrate with some public presentation abnormalities observed. The aim of this experiment was to utilize HALT quiver to set up the relationship between the life of similar parts soldered with different solder composings. The consequences proved inconclusive for the primary intent of â€Å" Sn95.5Ag4Cu0.5 † versus â€Å" Sn42Bi57Ag1 † articulation random quiver trial. Both composings demonstrated weak public presentation and the consequences may propose that with regard to this brief random quiver trial, solder articulation dependability is different between the two composings. No samples were separated from the trial vehicle as a consequence of the quiver applied. However, the trial procedure revealed insight into HALT and suggested factors which can impact consequences when soldered constituents are being compared. First, Printed circuit board kineticss would be understood and controlled so that acceleration hot musca volitanss and nothings are made more equal in amplitude. A flexible PCB will debar and bring forth bending emphasiss suited for measuring emphasis on solder articulations. But with a flexible board acceleration uniformity become hard to command and do a comparing trial less nonsubjective. Second, HALT random quiver is a good methodological analysis for bring forthing multi-axis wide spectrum energy for PCBs and their constituents. ( Wu J.2000 ) The typical method to analyze the functionality of a PCB in a quiver environment is to verify the quiver transmissibility. Normally the transmissibility at any location of PCB should be less than a factor of 10, i.e. , 1 G input will non bring forth more than 10 G end product at any location of the PCB. To accomplish this end, two methods can be applied to the PCB design. One is to restrain the PCB tightly to the fixture, which can be realized by bettering the boundary conditions in the finite component analysis theoretical account. The other is to relocate heavy affiliated constituents of the PCB board to allow optimum locations ( i.e. , mass re-distribution ) . ( Wu J.2000 ) Lead free solder assemblies have quickly been promote in the micro-packaging development to forestall the environmental pollution, issues on the dependability has non been clearly solved. Several experiments have been conducted on the soundness of alternate lead free soldering technique such as Sn-Ag-Cu solder. During the bumping procedure, a considerable thermic distortion is occurred and the chemical features of solder and bed qualities are besides changed in agreement with the surface completing method such as ET ( electric Sn ) , ENEPIG ( electro less nickel, electro less Pd and submergence gold ) etc. The IMC ( intermetallic compound ) bed is formed in a micro-scale part between the solder and the surface completing stuff under high temperature adhering procedure. In the field of micro-packaging together with IMC bed, one of the most hard issues is to mensurate width interface beds in a solder articulations. Since the IMC beds have been estimated as the weakest subdivision in th e solder articulations, a accurate finding of mechanical belongingss in the country of this critical part may supply direct and enhanced information to understand the break behavior. aˆ? . ( Zhang RR.2001 ) stringency of mounting bolt of PCB reduced during experiment. Due to this consequence the PCB stated to vibrate freely. Applied quiver force was non shared uniformly. From finite component analysis alterations in stringency of mountin bolt can be realize.Chapter 6DecisionThe decisions ensuing from this work are:.Interactions between temperature and quiver were found important and therefore had influence on concluding consequence. Stencil printing by manus affect the solder joint dependability. Better apprehension gained about electronic assembly behaviors when subjected to quiver. Gained cognition about electronic assembly procedure and how it is act uponing in solder articulation dependability. Gained good experience in managing event sensor and environmental proving chamber.Chapter 7FUTURE WORKSIn this undertaking investigated the consequence of quiver of solder articulation dependability in electronic assembly. For this probe two different types solder paste used, eventually all specimens were tested in environmental Chamber. In this undertaking when making quiver trial informations acquired by event sensor is non accurate value. From informations obtained from event sensor does non give proper analytical consequence. In sing about the hereafter works of this undertaking can be expand based on acquirable informations type, every bit good as finite component analysis because dependability of a solder articulation depends on assorted environmental factors, so result analysis will be more accurate and stand with more international criterions.
