UV Conformal Coating for PCB & PCBA
Conformal coating is a thin protective film that is applied to electronic components and printed circuit boards (PCBs) to protect them from environmental factors such as moisture, dust, and temperature fluctuations. The coating conforms to the contours of the component, providing a uniform layer of protection.
UV conformal coating is a transparent solvent-free, one-component, high-performance coating material that meets the latest requirements of the electronics industry. Fast curing by UV light and moisture curing, it still has good electrical insulation properties in harsh environments. This series of UV conformal coatings has a complete range and a full range of products with different viscosities to meet customers' various process requirements from thin film to thick film. The coating thickness range is 20~500 microns. Good reputation and high market share in the field of electronics and home appliances.
Conformal coatings can be applied using various methods, including spraying, dipping, brushing, and selective coating. Spraying is a common method because it can be used to coat large areas quickly and efficiently. Dipping is useful for coating components with complex geometries, while brushing and selective coating can be used for precise application of the coating.
