Capillary Flow

 

Typical failure mechanisms in conformal coating processing: Capillary Flow

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

Capillary flow in conformal coating is where the coating pulls or runs away from certain areas of a PCB or components.

The video will show the the causes, examples and how to prevent capillary flow in the conformal coating process.
