What are the common faults of board-to-board connectors?

In the design of board-to-board connectors, the initial contact force and stress relief are very important, because the elastic deformation of the contacts is transformed into plastic deformation, and the stress relief reduces the contact force, but when the contact force is lower than the horizontal value, its function will fail. Therefore, stress relief is related to the reliability of the board-to-board connector, which requires the design and material selection to be reasonable in structure and stable and reliable in performance.

If the board-to-board fails in use, it may be due to broken wires and poor contact from loose connector terminals. When checking, carefully check the wires and connection parts of the sensor, and consider other reasons when the lines are tightly connected. If a board-to-board connector breaks due to poor contact, impurities and external contaminants may enter the connector terminals, causing corrosion and reducing contact pressure.

The quality of a board-to-board connector has an important relationship with its appearance and performance. In the event of a failure, the first thing to consider is whether the design of the contact part of the board-to-board connector is unreasonable or the material selection is inappropriate, resulting in unstable performance. Then check whether it is caused by poor quality, such as the unreasonable insertion dimension tolerance value of the product, resulting in poor contact of the board-to-board connector. Additionally, board-to-board connectors can fail due to peeling or oxidation of the metal surface coating.

In use, the board-to-board connector needs to be protected. Improper protection can easily cause partial damage or corrosion of the connector, which is not only difficult to maintain, but also troublesome to replace. Only reasonable use can make the performance of the board-to-board connector more stable.
