Board to board connectors play an important role in the electronic communication industry. Components such as mobile phone batteries, displays, touch screens, cameras, etc. require board to board connectors, which are essential for high-speed transmission capabilities in cameras, tablets, laptops, and wearable devices. In order to adapt to lighter and thinner electronic products, board to board connectors with narrow spacing and high current have become the mainstream in the market.

Board to board connectors, also known as connectors, can be divided into male and female sockets to provide a stable connection. The terminal part serves as a conductor and is used to transmit current or signals. Narrow spacing board to board connectors need to ensure reliable connection and stable transmission, and enhance their conductivity. Therefore, in production, board to board connectors are usually coated with a layer of metal coating, including gold plating, silver plating, tin plating, etc. The plating process is of great help to the performance of board to board connectors, which can maintain stable connections, have strong corrosion resistance, and improve the durability and wear resistance of connectors.

Board to board connectors are used in conjunction with male and female connectors. When inserted and removed, due to the interaction of forces, it is easy to cause damage to the board to board connectors. Improving the gold plating strength of the contact surface of the connector during plating can greatly reduce the losses caused by friction, thereby improving the wear resistance of the board to board connector. When plating, there are also considerations in the process. Nickel plating is better than gold plating, and the thicker the nickel layer, the better. The smoother the surface of the board to board connector, the lower the friction force and the better its performance. In addition to the plating process, board to board connectors also need to be maintained during operation, which can reduce the loss of board to board connectors.
