Gidd Moerning all,
I have something that may be too far from PWB, but I dare try: who knows about noise in metal filled adhesive joints? Many years back people found that the conducting mechanism in thin silver epoxy joints reminds of that in semiconductors, i.e. you  have something like a diode, but very small forward current drops and hardly measureable reverse blocking, anyway, it may cause noise. Unfortunately, I have lost the article and the guy who made research in this issue (possibly IBM, Raytheon, HP... was american I'm sure). Anyone out there with experience from this field and RF-noise?
txs in advance
