Cause of the board-to-board connector failure

Board to board connector is an indispensable electronic component in electronic products. It can connect the power supply and signal. Its own advantages determine that it can better adapt to the development trend of electronic products miniaturization and give play to the best performance. Board-to-board connectors have the following advantages in application:

1. Can improve the assembly process of electronic products and simplify the mass production process;
2. Good contact resistance and mechanical impact resistance;
3. Salt spray resistance, anti-aging, UV resistance, can adapt to the harsh environment;
4. Easy to maintain, and can be replaced quickly when components fail;
5. Can update the meta parts at any time, with the new directly replace the old, easy to operate;
6. With super electric transmission function, stable and reliable connection.

The metal conductor inside the board-to-board connector is the core component of the whole. The metal conductor is the PIN pin/terminal, which is used to transmit the data signal and current of the external connected wire or cable. Both the initial contact force and the release of stress are important in the design of plat - to - plate connectors because the elastic deformation of the contact converts to plastic deformation. The release of stress reduces the contact force, and when the contact force is below the horizontal value, its function will fail. Therefore, the stress release is related to the reliability of the plate-to-plate connector, which requires good structure in the design and material selection, and stable and reliable performance.

The quality of the board-to-board connector has an important relationship with the appearance and performance. Once the fault occurs, the first consideration should be whether the design of the contact parts of the board-to-board connector is unreasonable, or the selection of materials is not in place, which leads to the unstable performance. Then check whether it is caused by poor quality, such as the unreasonable tolerance value of the product plug size, resulting in poor contact of the board to board connector. In addition, the metal surface coating falling off or oxidation and other reasons may cause the failure of the board to board connector.

If the fault occurs in the use of the board to board, it may be due to the poor contact caused by the broken wire and loose connector terminal. When checking, it is necessary to carefully check the wire of the sensor and the connection part, and then consider other reasons when the line is closely connected. If the board-to-board connector is disconnected due to poor contact, it is possible that impurities and external contaminants enter the connector terminals, resulting in rust, which reduces the contact pressure. When this happens, you need to remove and reinstall the board-to-board connector to change its connection status and bring the contact back to normal.
