Subject: Tin Whiskers
Message:
Is anybody here plugged into the Tin Whisker discussions going-on on the RoHS initiative? Pure tin used in solder joints grows whiskers over time and eventually cause shorts between adjacent pins? Based on the type of package it look possible to predict the failure rate due to tin whiskers for a particular package type. Is it possible to use this info to look at the MTBF of a circuit pack and determine the risk of failure?
