It has been demonstrated in numerous pieces of work that stencil printing, one of the most complex PCB assembly processes, is one of the largest contributors to defects (Revelino et el). This complexity extends to prototype builds where a small number of boards need to be assembled quickly and reliably. Stencil printing is becoming increasingly challenging as packages shrink in size, increase in lead count and require closer lead spacing (finer pitch). Prototype SMT assembly can be further divided between industrial and commercial work and the DIYer, hobbyist or researcher groups. This second group is highly price sensitive when it comes to the materials used for the board assembly as their funds are sourced from personal or research monies as opposed to company funds. This has led to development of a lower cost SMT printing stencil made from plastic film as opposed to the more traditional stainless steel stencil used by industrial and commercial users.This study compares the performance of these two traditional materials and their respective impact on solder paste printing including efficiency and print quality.

Today’s customers are more enlightened and aware demanding quality and compact electronics products at competitive prices. Today when a single word spreads out so quickly, no company can afford to put their reputation at stake by manufacturing substandard products.

With the increase of labor costs, the popularity of automated production lines, • Antistatic ic tubes, connector shipping tubes, power module shipping tubes, LED shipping tubes, relay shipping tubes and other electronic components tubes are also becoming more widely used. Many small companies blindly pursue low-priced packaging materials, and there is no requirement for quality. When it is later discovered that the parts are stuck in the packaging process, they will regret it when they crush the parts during transportation. Shenzhen Sewate Technology Co., Ltd. tells you about six ways to identify quality packaging tubes.

This paper will focus on two challenges: building differentiated products, which can enable systems companies to quickly penetrate a market, take a leadership position, and effectively counter or displace any competition; and build them faster. Clear differentiation also allows a superior value proposition, which will enable a stronger position on pricing with less need to circum to eroding ASPs. Differentiation can involve many factors, but this paper will focus on those related to the technology impact/usage that directly enables the design of products with shorter, more predictable design cycles compared to the competition.
