Conformal Coatings

Conformal coatings are materials applied in thin layers (typically 0.1 to 0.3mm) onto printed circuit boards or other electronic substrates. They provide environmental and mechanical protection to significantly extend the life of the assembly.

Conformal Coatings

Description

Conformal coatings are traditionally applied by dipping, spraying or simple brushing, and increasingly by select coating or robotic dispensing.

Conformal coatings protect PCB’s from moisture and contaminants, preventing short circuits and corrosion of conductors and solder joints. They also minimise dendritic growth and the electromigration of metal between conductors. The use of conformal coatings protects circuits and components from abrasion and solvents. Stress relief can be provided, as well as protection of the insulation resistance of the circuit.
