Interesting thanks.
If you do survey suppliers and they reply, (don't forget all the world
and his brother is writng to them on this so they might be a bit
overwhelmed), I think you will find that a large number of passive
suppliers are already using Sn as a finish, whether devices are marked
Pb-free or not.
I say whether they reply or not as I recently attended an in-company
Pb-free day. The host advised that they had simply asked suppliers if
they had a Pb-free plan and who was in charge of it. Less than 1 in 3
responded. And only a half of those were positive. I suppose you have to
assume that the rest did not have a plan....

Subject: [TN] Components Suppliers who are using Tin Finishes
Hi All!
I've been asked by one of our sales folks what we are doing to try and
prevent the problem of Tin whiskers from occuring on the products that
we build...apparently he was asked that from a potential customer.
I've been doing some researching and studying the topic through net
searches and whatnot, and found a good paper at:
http://www.calce.umd.edu/lead-free/tin-whiskers/TINWHISKERMITIGATION.pdf
One of the things it said to do was to determine if any of the component
suppliers that you use, are using or considering using Tin finishes.
Does anybody know of a listing somewhere that shows what finishes
component suppliers are using? Or does one have to just call and ask
each one?
Appreciate any information...
