Ken,
Below is a link to a nearly finished Office of Naval Research, ManTech
Research Project on Tin Whisker Mitigation if that helps.

Subject: [TN] Lead-Finish Question


Here's a question for all the high rel people out there. We've received
a couple of notifications from major component suppliers that they will
no longer supply the parts we need with a SnPb finish. Instead they are
only supplying them with "Matt (Matte) Tin" finish. They do not talk
about any under plating which would be desirable for minimizing tin
whiskers.

How are you people who build for DOD and medical handling these
situations? Am I being too sensitive about Matt Tim?

By the way these are single source and SMT parts.

Thanks in advance,

KennyB
