This study investigates the technological properties of quaternary or quinary alloys made by addition Bi or Bi and Sb elements to the SnAgCu solders. The influence of added elements on the electrical and mechanical properties of solder joints created by these solders between PCB and electronic components were evaluated.

The measurement of the conformal coating thickness on a printed circuit board (PCB) to ensure internal and international standards are met is now a critical factor in conformal coating process control. There are several methods for measurement of conformal coating thickness and they fall into two categories. These categories are wet film measurements applied during coating application and dry film measurements made after the coating is dried enough not to damage the coating.

Semiconductor manufacturing is characterized by very complex process flows made up of individual process steps, many of which are built to very close tolerances. Furthermore, there are complex interactions in these process flows, whereby each process step can affect many other steps, and each final device parameter might be determined by the results from many inputs...

Stereolithography is a handy tool not only for speeding a design to market but also in giving customers an early edge. By allowing a form-and-fit sample to be quickly made from a computer model, stereolithography coupled with simultaneous engineering allows customers to see product models early in the design cycle. And if a picture is worth a thousand words, what's a tangible sample worth?

This paper is a report of a study made to determine the maximum allowable impurities in solder used for wave soldering applications. This report concludes with a list of impurities compiled from actual analyses of solder which caused production problems. A list of recommended maximum allowable impurities will assist in establishing reliable quality controls on the purity level of the solder in a wave soldering machine.

The supply chain is made up of all the activities that are required to deliver products to the customer - from designing product to receiving orders, procuring materials, marketing, manufacturing, logistics, customer service, receiving payment and so on. Anyone, anything, anywhere that influences a product’s time-to-market, price, quality, information exchange, delivery, among other activities is part of the supply chain.

Many solder users have preconceived notions and worries involving reflow profiling guidelines. Year after year of reading profiling recommendations in industry publications, from a litany of pundits, has made it clear that perfect profiles exist and should be sought after. They feel if the solder supplier gives them a tidy drawing on a piece of paper with times and temperatures that it will magically solve all their reflow problems. This is, unfortunately, an often incorrect assumption.
