Good Day All:
I've posted a similar question on technet, but I thought this forum would be
more appropriate.

What are the problems, if any, with using lead-free components with a PbSn
SMT process?  Are there any compatibility issues?  How about long-term
reliability for military products?

Also, is anyone concerned with the influx of components with pure tin
finishes with regard to tin whiskers?

One more thing...  are there concerns that "custom" components, specified
with a PbSn finish, might become extinct (DMS, diminishing manufacturing
source)?

Thanks for your advice,
