Conformal Coating

Esprit can offer various methods and materials for conformal coating PCB assemblies. Meeting the requirements of material specifications IPC-CC-830B and Mil-I-46058C, using guidance from IPC-HDBK-830. Our primary materials are Acrylics, these being Humiseal 1B31 and IB73.

Application methods we can offer are :-

Brush coating works by flow coating the material onto the board and is suitable for low volume application, finishing and repair.

Spray application coating can be completed with a spray aerosol or dedicated spray gun in our dedicated spray booth is suitable for low and medium volume processing. “shield” than “barrier” since the penetration is less effective. However, the lack of penetration can be an issue where coating is desired to penetrate under devices.

Selective processes involves needle & atomised spray applicator that can move above the circuit board and dispense / spray the coating material in selective areas. Flow rates and material viscosity are programmed into the computer system controlling the applicator so that the desired coating thickness is maintained.

This method is highly effective at large volumes.
