Hi Everyone, Having trouble with conformal coating. Currently using a UV cure silicone based spray on a PCB with gold plating. The problem we are experiencing is after the conformal coating is applied and curred (0.002" thick), using simple probes with very little pressure on the probes, we obtain conductivity between certain traces. In other words, the conformal coating is not preventing electrical conduction between points. Specificially, we are having difficulty coating vias and SMT resistor/capacitors. We tried increasing the thickness of the conformal coating sprayed, but no luck. Does anyone have any ideas?
