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
