Conformal Coating

FOVAC® Conformal Coating is a thin polymeric film typically applied at 25-250 μm to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes. The coating ‘conforms’ to the contours of a printed circuit board (PCB) to protect the board’s components. When electronics must withstand harsh environments, most circuit board assembly houses coat assemblies with a layer of transparent conformal coating. In addition, Conformal coatings are being used as a mitigation to reduce the potential of tin and zinc whisker short circuit risk on electronic assemblies using lead-free finishes and solders.
