Conformal coating is a thin transparent polymeric coating applied to PCB’s to provide protection from the end-use environment. Common types of conformal coatings include acrylics, urethanes, epoxies, silicones and polyparaxylylene. They are typically applied at 1-5 mil thickness. Conformal coatings have many common functions, such as inhibiting current leakage due to environmental contamination, inhibiting corrosion, improving fatigue resistance of solder joints, inhibiting arcing and corona, providing mechanical support. Meanwhile GOLOHO
conformal coating products can meet the critical demands with the reduction in component size, pitch, circuitry spacing, and laminate thickness.
