Typical failure mechanisms in conformal coating processing: Cracking

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

The cracks in the conformal coating leave the surface area below exposed to potential contamination penetration. This allows moisture, water and debris to reach the board level where other defects could then occur such as corrosion.

Watch this video to know how to prevent cracking in the conformal coating process.
