Assessment of the Reliability of Lead-Free Solder Joints

Assessment of the Reliability of Lead-Free Solder Joints (Binghamton University)

Almost all accelerated testing done by industry are so-called “engineering tests” intended to compare performance. However, accelerated testing may be very deceptive unless the results can be counted on to somehow reflect performance in service. Reliability engineers need to know when “best in test” is unlikely to mean “best in service,” how large deviations may be, and which comparisons can be counted on to be conservative.

Binghamton University has developed a model for determining the thermal fatigue of lead-free solder joints. Their approach allows for the generalization of observed trends and leads to recommendations for test protocols and guidelines.
