Posted by Sean Horn on Fri, Nov 11, 2016

Conformally coated PCBs are expected to work without fail, largely because of the protection the coatings provide them.  In addition to PCB-manufacturing issues, coating problems can trigger failure mechanisms for the assembly.  For instance, Conformal coating applied incorrectly can cause PCB malfunction. Selecting the wrong coating material from among acrylic, epoxy, parylene, silicone or uret
