Conformal Coating and Potting PCBA Service Outdoor, marine and automotive electronics fail at the surface long before the circuit does. This service adds a controlled conformal coating or full potting layer to a finished PCBA so the board resists moisture, salt spray, dust and thermal cycling, reaching IP65 to IP67 depending on the enclosure and material chosen.
