Conformal Coating ensures the long-term reliability of electronic assemblies, especially in safety-critical applications. Applied to printed circuit boards (PCBs), the protective coating shields sensitive electronics from dust, contamination, humidity, condensation and temperature fluctuations.

As PCB densities increase and components become smaller, conformal coating becomes essential. Its insulating properties allow reduced spacing between conductors while maintaining electrical reliability and improving device performance.

Conformal Coating Inspection (CCI) uses automated optical inspection (AOI) to ensure consistent coating quality during electronics manufacturing. Inline inspection systems verify coating presence, uniform coverage and surface quality in real time.

Viscom’s CCI systems support a wide range of coating materials, including silicone, acrylic and hybrid coatings. Using UV illumination and advanced camera technology, coating defects such as scratches, bubbles, orange peel surfaces, excess coating or missing coating areas are detected with high precision, even in complex PCB assemblies.
