I'm wondering whether all the dendrites are pure Sn? In my previous life I saw very similar problem with capacitors, but the dendrites were "made" of Pb and drew under a conformal coating.

Mornin' All!

David Douthit sent me pictures to post that did jog my memory...go to:

http://www.stevezeva.homestead.com

and look at Capacitor Dendrites. Looks like conditions may be ripe in the
previous pictures that I posted.
