Hi I am looking for some type of peelable mask or plug to cover the connector during the conformal coating. The problem we have is the moisture get into system and eventually penetrate under the connector creating short circuit to the board. What I r

Once the HumiSeal conformal coating has been applied to the printed circuit board it is usually best to allow the material to reach a touch-dry stage, before heating the board to accelerate the cure schedule. This avoids potential problems such as bu

Same line of thinking with Pete here. Why thin board and thick coating? Did you consider to use underfill instead?

What your said looks like a acrylic coating thermal expansion causes small solder joint crack. Do you cure coating with heating, or heating after curing? Solder joint crack while you see resistor and QFN trouble? Clear and detail description of your

Hi All! There were a few rigid flex assemblies brought to me this morning with some scratches in the coverlay of the flex. They are pretty minor, but they do go down into some traces a bit. I don't think the traces are really signal traces, but are
