International law is founded upon the notion that states are juridically equal. One of the consequences of this legal equality is the principle of reciprocity whereby each state party to a treaty has the same rights and obligations. In practice, states vary greatly in wealth, resource endowment, military strength, size and population. These differences or inequalities influence, for instance, political clout in the international arena or the capacity to implement certain treaties. The concept of judicial equity has been known to different legal systems for a long time. This constitutes an acknowledgement that formal equality may lead in justice. This is an excellent tool to address situations which are inherently unusual. Where the results brought about by the application of formally equal rules do not necessary to devise different schemes which fulfil the same goals as judicial equity. Differential treatment does not encompass every deviation from the principle of sovereign equality. In refers to non-reciprocal arrangements which seek to foster substantive equality in the international community. In practice, this mainly includes deviations which seek to favour least favoured states. The latter con often be equated with developing and least developed countries. This categorization if relevant in a number of cases because economic development is of prime importance in a number of fields covered by international cooperation, such as trade, and because it is often correlated with levels of political or military power. However, the level of economic development is not the only why to categorize states for purposes of differentiation and this has been acknowledged in the practice of international institutions.

International Economic Law, especially The GAIT and WTO Agreements have granted developing countries various special and differential treatments. So developing country status in the WTO brings certain rights. There are for example provisions in some WTO Agreements which provide developing countries with longer transition periods before they are required to fully implement the agreement and developing countries can receive technical assistance. But SDT provisions in the WTO have come under increasing criticisms in recent years by developing countries. They include supply inadequate provisions (TRIPS, TRIMS, Subsidies), insufficient technical assistance, market access difficulties..etc. Subsequently, the review of SDT was the main crucial issue that they introduced to the WTO Ministerial Conference in Doha in November 2001. However, today, negotiations are still in a deadlock because of a conflicting debate between developed countries focusing on cross cutting issues and developing countries arguing for an agreement specific proposals regarding how to improve the development content of SDT.

In this study, analyses on the stencil printing using solder paste were carried out. The key design parameters in the stencil printing process are printing conditions, stencil design, and solder paste properties. Among these parameters, the effects of physical properties of solder paste such as viscosity, surface tension, and contact angle on the stencil printing process were investigated. The analyses were performed for simple geometry and boundary conditions. In the analysis, solder paste was pushed into a stencil hole by pressure instead of printer pad. Considering the geometry and computational efficiency, axisymmetric analyses were adopted. A commercial software (COMSOL), which is well known in the area of micro-fluids analysis, was used. From the results, it was shown that viscosity of solder paste had an effect on the filling speed, while surface tension and contact angle had an effect on the filling shape. 본 연구에서는 솔더 페이스트를 이용한 프린팅 공정의 해석에 대해 연구를 수행하였다. 스텐실 프린팅 공정의 설계에서 중요한 인자는 프린팅 조건, 스텐실 설계, 그리고 솔더 페이스트의 물성 등이다. 본 연구에서는 이 인자들 중에서, 솔더 페이스트의 점도와 표면장력, 그리고 솔더 페이스트와 스텐실 사이의 접촉각이 프린팅 공정의 성능에 미치는 영향을 해석을 통해 파악하였다. 실제 해석에 앞서 압력에 의해서 솔더 페이스트가 스텐실에 채워지는 단순화된 형상과 조건으로 해석을 수행하였다. 해석은 마이크로 유동의 해석에 많이 이용이 되고 있는 상용 소프트웨어인 콤솔(COMSOL)을 이용하였고 축대칭으로 해석하였다. 해석 결과, 솔더 페이스트의 점도는 충진률에 큰 영향을 줌을 알 수 있었고 표면장력과 접촉각은 충진되는 형상에 영향을 줌을 알 수 있었다.
