Conformal Coating Dilemma

Conformal Coating Dilemma | 26 July, 2005

I have a single sided PCB that contains 4 RF connectors that will require conformal coating. Sounds easy, well the RF connector is .080 in diameter and stands a whole .050 in height. The sub-straight that the barrel sits on is about .020 thick. I don�t see there is a way to mask these off and still cover the leads with Humiseal and if you apply the Humiseal using a swirlcoat and get it to cover the leads it typically is also migrating up the outside of the barrel. Anyone have any thoughts BESIDES SHOOT THE DESIGNER!
