Conformal coating in the process of use, due to process problems, there will be the following phenomena:
Bubbles: Large bubbles, small bubbles or large and small bubbles appear simultaneously
White: the film contains water or other liquid, the color of the film is lighter than the original, and the film shows a white fog.
Layering: The phenomenon of layering in the three anti-paint is mainly in the components and welding layers.
Orange grain: The scene of orange grain in the three anti-paint is caused by forced drying.
Cracks and scratches: the cracks of the three anti-paint are mainly due to the thickness of the film, where the surface tension is too large, such as the pin and the edge of the component.
Capillary phenomenon: The capillary phenomenon of the three anti-paint comes from the following aspects: affected by the following problems:
board design: small-pitch tube leg connector; Excessive coating requirements; Three anti-adhesive viscosity is too low; Three anti-glue flow is too large; The surface tension between the substrate and the three adhesive is inappropriate.
Sharp coating three anti-paint series features: insulation, flame retardant, moisture, corrosion, salt spray, temperature change and so on; Three anti-paint products have UL, RoHS, REACH, TS16949 and other certificates, with product carbon footprint certificate.
Widely used in PCBA/BMS/LED/ electronic appliances and so on.
