ISTR someone also had previously posted a link to some pictures on the NASA
web site showing the problem with crystalline whiskers with tin. I think
the issue here was that such whisker growth is significant less with
traditional leaded solders than the lead-free ones. If this is true, and as
we moved towards closer pin placement and higher densities, this could make
long term reliability an issue.
Anyone have any more info that aspect?
