Lead-free electronics continues to be a concern of the aerospace, defense, and high performance products (ADHP) industries. This is primarily due to the lack of data and knowledge to: thoroughly categorize performance under harsh service conditions and provide a level of confidence in reliability assessments of Pb-free electronics equal to those for traditional tin-lead electronics. To help close...

Manufacturers of high reliability electronics have been working for many years to mitigate the deleterious effects of tin whisker formation. One highly effective means to suppress the growth of tin whiskers is to replace the pure tin plating with reflowed tin-lead solder. One approach is to fully consume the tin plating by tin-lead solder during the SMT reflow process. This phenomenon of tin...
