Hi Steve,
You sure got your problems.
Yes, Ag-embrittlement is similar to, but actually worse than 
Au-embrittlement, and for the same reasons. Of course, combining them is giving you 
AghhhAuhhh-embrittlement [or is it Auhhh Aghhh?].
TSOPs, unless made with a Cu-leadframe are bad news; there CTE's are c'ose to 
ceramic because of the alloy-42 CTE (a magnet can tell you). ...and TSOPs do 
not deserve to be called 'leaded components.'
This compress a fractured SJ is used by a lot of people who's laptops are 
conking out because of SJ-failures.

Werner
