What should I do if the board-to-board connector is worn out after a long time of use?

Board to board connector connector life depends on the insertion and extraction, which inserted and pulled out of the two sides of the force under the interaction of improper operation can easily lead to board to board connector wear, time will result in the internal pin components will cause wear and tear to the rear leading to damage, then how to go to reduce the wear of the board to board connectors? In fact, the general board-to-board connector end pin to reduce wear and tear, on the one hand, to improve the strength of the contact surface of the gold-plated layer, which can effectively reduce friction. On the other hand, the inner end pin of the board-to-board connector contact nickel layer is thicker, the gold-plated layer of wear resistance is stronger, but also because the smoother the surface, the lower its roughness, the smaller the friction, but the connector's material, the general price will be relatively high, so the user can choose a more suitable board-to-board connector to use according to their own needs. 1. The current will generate heat at the contact point, resulting in temperature rise, so the operating temperature of the board-to-board connector should be equal to the ambient temperature and the temperature rise of the contact point and the sum of the board-to-board connector. 2. Board-to-board connector is wet, moisture invasion will affect the insulation properties, metal parts parts will be rusted, so you need to specify the test conditions, relative humidity of 90% ~ 95%, the temperature of +40 ± 20 ° C. 3. Board-to-board connector in the containing salt spray When the board-to-board connector works in the environment containing salt spray, the contact surface and metal structural parts may produce galvanic corrosion, thus affecting the electrical performance of the board-to-board connector, and can not be used directly.
