     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.

Currently, I have observed some boards with Tin Whiskers growth.  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?
     
Thank you in advance
