From: Tuan300859 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?
