Delamination

 

Typical failure mechanisms in conformal coating processing: Delamination

This video is about one of the typical failure mechanisms in conformal coating processing called  Delamination.

Delamination in conformal coating process happens when the conformal coating lifts from the surface of the PCB which leaves the circuit board area below exposed.

The video details the tells of the causes, examples and how to prevent delamination in the conformal coating process.
