What are the usual causes of poor board-to-board connector contact?

There are many reasons for poor board-to-board contact, poor board-to-board contact can be caused by board-to-board connector disconnection and failure, usually because the connector end of the corrosion, outside dirt into the terminal or connection socket inside, resulting in a reduction in contact pressure. At this time we should remove the board to board connector, and then re-inserted to change its connection status, so that normal contact can be restored.

In addition, the board-to-board connector failure may also be caused by poor contact with the board's wires, board-to-board connector disconnection failure, because the wire breaks in the use of the wire in the middle of the disconnection failure is very rare, most of the connector is disconnected, therefore, usually we need to check carefully when checking the connection to the wire at the Shun, whether there is also a phenomenon of poor contact, and at the same time, pay attention to avoiding the board-to-board connector is subject to moisture and dust intrusion, etc.. Board connectors are subject to moisture and dust invasion.
