Ruggedization and Conformal Coating

Posted by Sean Horn on Fri, Jan 5, 2018

Conformal coatings are non-conductive dielectric film-coverings applied over printed circuit boards (PCBs) to protect them from damage caused by chemical incursion, corrosion, current-leakage, dirt/dust, extreme temperatures, fungus, moisture, rain, salt-spray, wind and persistent, intensive vibrations both within and external to the device. These failure mechanisms can soon lead to PCB malfuncti

Military Conformal Coatings: Acrylic vs Urethane vs Parylene

Posted by Sean Horn on Fri, Nov 24, 2017

Conformal Coatings For Military Electronics Military electronics need to operate without fail under conditions of extreme duress. The role of conformal coatings — acrylic, urethane, and parylene — as protective insulators of the printed circuit board (PCB) assemblies that guide automated military systems is well-documented, and continually under review to develop enhanced performance p

Available in five basic material types, conformal coatings can be readily adapted as protective, insulating films for electronics. However, there can be some confusion about which type is best-suited for a specific use. Clearly defining the performance parameters for the component[s] to-be-coated helps coordinate the conformal film material with a unit’s functional requirements. Accurate assessm
