Hi TechNet: Two good sources of information on tin whisker phenomena are: the AMP web page - there is a good technical article that covers tin whiskers; And chapter 6.7, page 197 of R.J. Klein Wassink's book "Soldering in Electronics", ISBN # 0-901150-14-2. Both sources give good, simple summaries of industry knowledge of tin whiskers. Good Luck.

The whiskers seem to grow from the Tin-lead pads(unusual). The phenomenon is occurred at only one side of the QFP180 component on the board. Here are my questions: 1. What is/are the root cause(s) of the Tin Whisker? 2. Are there experiments or tests that had been done? 3. If no to both questions above, Are there any literature that I can read up to help determine the root causes of the Whisker?
