The main use of hard gold PCBs is to provide contact points and PCB edge connectors. It is often used in high-end electronic products, such as communication equipment and military equipment, and can provide excellent electrical performance and reliability. In addition, hard gold PCBs are often used in areas that need to withstand friction and pressure, such as contact points in motor control boards.
Because hard gold PCB has high hardness, high wear resistance and good electrical conductivity, it can prevent oxidation and corrosion on the PCB surface and is suitable for circuit boards that require frequent maintenance and disassembly. At the same time, hard gold PCB also has good welding performance and is suitable for circuit boards that require frequent repair and disassembly.
In short, hard gold PCB has high hardness, high wear resistance, good electrical conductivity and welding performance. It is mainly used in high-end electronic products and parts that need to withstand friction and pressure.
