What is layering in conformal coating and is it a problem for the protection of the circuit board?

Layering is where multiple coats of material are applied to a circuit board and they do not adhere to each other or cause incorrect curing of the individual layers.

This can lead to a weakened performance in the conformal coating, which in turn can lead to the failure of the circuit board.

There are several causes of layering in conformal coating. These include incorrect adhesion, curing and keying of the coatings.
