How to avoid de-wetting of conformal coating

De-wetting is the where the conformal coating material refuses to wet the surface of the circuit board that it has been applied to in an even way. The coating ends up being patchy.

The de-wetting effect tends to act locally due to local contamination.But, it can be a global affect right across the board.


De-wetting of the conformal coating can be localised or all over the circuit board.

There are many causes of De-wetting in Conformal Coating.

These include contaminants such as residues and oils, and processes such as soldering and cleaning.
