Considering the simmilar embrittlement effect of Ag ; as in Au ;
is there some recognised volume content (as if I remember correctly 4% of
Au[Klein Wassink])of Ag in a joint ?
Some of the Ag alloys cycling results did not look so hot . ?
Thanks a lot

The PAd/Ag mostly dissolves on soldering so make sure that you specify the
component to have a nickel barrier coat or underlay otherwise you stand a
good chance of getting down to bare ceramic. This is a standard presentation
and should not be a problem for your supplier.
