Cracking in Conformal Coating: Major Causes and Preventative Strategies

Posted by Sean Horn on Fri, Feb 10, 2017

Conformal coatings protect printed circuit boards (PCBs) and similar electronic assemblies used for a wide range of aerospace, automotive, consumer, defense and medical applications.  Coatings effectively cover PCBs, shielding them from contaminants, liquid incursions, temperature fluctuations and other conditions potentially hazardous to component performance.  However, problems can develop if

Why Conformal Coat

Posted by Sean Horn on Tue, Jul 16, 2013

Printed circuit boards are extremely susceptible to a wide range of contaminants that can significantly damage or ruin them in a relatively short period of time. These contaminants include moisture, dust, and harmful chemicals. In addition, electronic circuits are also susceptible to extreme temperatures and environments.

What Causes Bubbles In Conformal Coating?

Conformal Coating Bubbles One of the major causes for failure during conformal coating inspection are bubbles.  Bubbles are trapped pockets of air under coating.  The bubbles can cause voids in the coating and Here we will identify the six largest causes of bubbles.
