Conformal coating helps protect your valuable, finished electronics assemblies.
A conformal coating material is a thin, protective barrier that shields sensitive electronic components. Typically applied at 25-250 μm (micrometers), it is applied to electronic circuitry to protect them from harsh environments that may contain moisture, debris, or chemical contaminants. If a board is uncoated (non-protected), environmental conditions can damage the electronics and cause failure.
The coating provides a barrier to air-borne contaminants (such as salt spray) from the operating environment. This prevents corrosion. Conformal coatings are breathable – the coating layer protects against many environmental hazards but allows any moisture trapped in the coated circuit board to escape.
