Conformal Coating Failure: 6 Common Causes

Posted by Sean Horn on Tue, Aug 06, 2013 @ 08:13 AM

Conformal coatings frequently play a critical role in protecting medical, electronics, defense, aerospace, LED, and automotive applications from contaminants and other potentially hazardous substances. But they're not infallible.

How thick should silicone conformal coating be applied?

Posted by Sean Horn on Tue, Oct 09, 2012 @ 06:51 AM

Silicone conformal coating is quickly becoming a very popular choice for conformal coating.  Many people are asking for silicone coating because of its excellent moisture resistance, quick drying nature, and high temperature capabilities.  It is also one of the easiest conformal coatings to work with.  In order for the coating to function at its optimum level, it has to be applied at the proper thickness.

Maintaining proper thickness for silicone conformal coating is critical because it is applied very thick compared to other conformal coatings.  If a coating is applied too thick, it may create excessive stresses on solder joints and components (particularly glass-bodied components).  If a coating is applied too thin, it may not reach the optimum properties described on the Technical Data Sheet.  For this reason, the IPC created the J-STD-001 to regulate and standardize the thickness that coatings are applied at.  For silicones, the J-STD-001 calls out 0.00197 to 0.00827 in.  Our operators strive to hit between .002” and .008” for silicone applications.

Conformal Coating Rework and Repair

Posted by Sean Horn on Mon, Aug 20, 2012 @ 09:15 AM

Stripping or removal of unwanted conformal coating from a printed circuit board (PCB) can be a relatively simple process or a very messy difficult job. It does depend on several factors including the type of conformal coating you need to remove, where the coating is found and the type of components on the board.

Automated Conformal Coating Spray Robot Issues

Posted by Sean Horn on Fri, Jun 01, 2012 @ 02:17 PM

There are many benefits to using a spray robot for conformal coating.  As always, there are some potential issues that need to be addressed prior to committing to a spray robot such as the MACCS 400.

 One potential issue with considering selective conformal coating with a robotic conformal coating system is misaligned components on the PCB which can potentially damage the spray heads which are moving along a set pattern on the board and the components themselves be damaged as they travel.  Spray heads are one of the most critical parts on the spray robot.  Repairing damage can get costly.
