Interesting thread which prompts me to raise a related question. I'm using silver epoxy as part of an EMC/ESD shield. It connects a conductive enclosure to a PWB ground plane. Generally we get a DC resistance across the epoxy joint of about 3 Ohms. However after we subject a device to an ESD spike we find the resistance drops by maybe an Ohm or so. Anyone got an idea what's happening?
