Ancham PM7005: An efficient invisible barrier for selective three-proof coating

As electronic products become increasingly sophisticated and miniaturized, and are widely used in harsh environments such as high humidity, high dust, and high corrosion, the-proof coating process has become a critical link to ensure the long-term reliability of PCBs. However, not all areas on the board need or can be coated. For example if connectors, battery holders, switches, debugging interfaces, optical sensors, and other parts are covered with three-proof paint, it will lead to functional failure or performance degradation.
