Hard gold PCB, also called hard gold electroplated PCB, is a special type of PCB board. It uses a hard gold plating process to cover the PCB surface with a layer of hard gold (Gold) to enhance its conductivity and corrosion resistance.
The main components of hard gold plating are pure gold and other alloying elements, which make hard gold PCB have high hardness, high wear resistance and good electrical conductivity. It can prevent oxidation and corrosion on the PCB surface, provide good soldering performance, and is suitable for circuit boards that require frequent maintenance and disassembly.
Hard gold PCB is often used in high-end electronic products, such as communication equipment, military equipment, etc., and has excellent performance in electrical performance and reliability. At the same time, hard gold PCB is also often used in parts that need to withstand friction and pressure, such as contact points in motor control boards.
In short, hard gold PCB is a special type of PCB board made by hard gold plating process. It has high hardness, high wear resistance and good electrical conductivity. It is suitable for high-end electronic products and parts that need to withstand friction and pressure.
