Hi,
I've just been reading a new item on the
NASA Goddard Space Flight Center Tin Whisker (and Other Metal Whisker) Homepage, specifically
"Evaluation of Conformal Coatings as a Tin Whisker Mitigation Strategy, Part 2".
It seems the whiskers managed to penetrate the various coatings tested.
Fascinating stuff. But, going by that research, it looks like coating the inside of our transistor cans will merely slow whisker growth down a bit.
Regards, Kat
