David,
You have requested so much in one e-mail. I have tested Minico, which is Ag
plated copper particles, on flex. I published a paper at SUR/FIN 99 on
Immersion Ag onto Cu to be used as flex circuits. When do you need all of
your questions answered?
Call me if you want me to do a brain dump on you. My boss says  can spent
some time with people on the phone without a price tag.
