Conformal coating

Both dip-coating and vertical spray coating is available. Protecting non-conductive dielectric layer that is
applied onto the printed circuit board assembly to protect the electronic assembly from damage due to
contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.
When coated, it is clearly visible as a clear and shiny material.
