FAQ’s
PCB conformal coating is a thin protective layer applied to a circuit board and selected components. It helps protect electronics from moisture, dust, corrosion, chemicals, and other environmental contaminants.
Common types include acrylic, silicone, polyurethane, epoxy, and UV curable conformal coating. Each type offers different combinations of flexibility, environmental resistance, curing characteristics, and reworkability.
The coating should be selected according to operating temperature, moisture exposure, chemical conditions, flexibility, thickness, and curing requirements. PCB design, component compatibility, production method, and required service life should also be considered.
Depending on the PCB and production requirement, coating may be applied by spraying, brushing, dipping, selective coating, or another controlled method. Before application, the board should be properly prepared, and required connectors, test points, and other areas should be protected from unwanted coating.
The coating creates a protective barrier between sensitive electronic surfaces and external environmental contaminants. When the correct material and coverage are used, it can help reduce moisture ingress, contamination, chemical exposure, and corrosion-related damage.
