What causes the board-to-board connector failure?

Board - to - board connector is an electronic component in electronic products that can be connected to power and signals. Its own advantages decide to better accustomed to the development trend of electronic products miniaturization, play the best function. Board-to-board connectors have the following advantages in applications:



connector

1. Can improve the assembly process of electronic products and simplify the mass production process;

2, with good touch resistance and mechanical impact resistance;

3, salt spray resistance, aging resistance, UV resistance, can get used to harsh environment;

4, easy to repair, parts can be quickly replaced when the fault;

5, the components can be updated at any time, the old can be directly replaced with new, simple and convenient operation;

6, the electric transmission function is strong, the connection is stable and reliable.



The metal conductor in the board-to-board connector is the faulty or missing core component. The metal conductor is the PIN pin/terminal used to transmit data signals and current connected to the external wire or cable. The initial touch force and stress release are very important in the planning of board-to-board connectors, because the touch portion transforms to plastic deformation after elastic deformation, then reduces the touch force, and its function decreases below the horizontal value when the touch force decreases. Will lose. Therefore, stress relief is related to the robustness of plate-to-plate connectors. In the planning and material selection requirements have excellent structure and stable and reliable function.



The quality of a board-to-board connector has an important relationship with appearance and function. Once the fault occurs, it is necessary to consider whether the touch part of the board-to-board connector is unreasonable, or whether the material selection is not in place, resulting in unstable function. Then check whether the quality is not good. For example, the tolerance value from the product to the plug size is unreasonable, resulting in poor touch of the board-to-board connector. In addition, peeling or oxidizing metal surface coatings can cause defects in plat - to - plate connectors.



If the board to board is faulty in use, it may be because of broken wires and loose connector terminals resulting in poor touch. When viewing, you should carefully check the wire of the sensor and the connecting part, and consider other reasons. If the board-to-board connector is opened due to poor touch, impurities and external contaminants may enter the connector terminals and cause rust, then the touch pressure is reduced. In these cases, you need to remove the board-to-board connector and reinstall it to change its connection condition so that the touch returns to normal.



In operation, it is necessary to protect the board - to - board connector. Improper protection is easy to form local damage or corrosion. It is not only difficult to protect, but also difficult to replace. Only reasonable use can make the function of board to board connector more stable.
