Greg, you are challenging our patience, aren't you(small giggle, hope they can accept that). I mail some pictures offline to you from Ag/Pd end cap ceramic capacitors that showed silver migration under humide to wet conditions. Bad, very bad copies. As I have written hundreds of technical reports, I can't save everything, however, I will look in our secretary's corner, maybe with some luck the original will come up. Migration caused shorts within 10 seconds in worst cases. By adding humidity absorbers in that part, no more troubles are heard. That was many years ago. The show was not in a very scientific way, just an attempt to verify artificially what happened in product's reality.

cu offline, hillabilly

PS. I used some non-techno words above, I apologize.
