How to Mask for Conformal Coating

Posted by Sean Horn on Fri, Jan 12, 2018

Liquid conformal coatings provide inexpensive, easily-applied insulative protection for printed circuit boards (PCBs) and similar electronics. However, the films’ otherwise desirable insulative qualities can interfere with operation of the assemblies’ electrical components, items like capacitors, connectors, diodes, resistors, or transistors, if these are coated. Liquid coatings are designed t

Operationally, conformal coatings are applied to the surface of PCBs and related electrical components, to insulate and protect them during use. Coatings improve PCBs’ performance under any circumstances, but are especially valuable for their functional tolerance to harsher working environments.
