Pogopin The main function of the connector is to connect, it can keep the device continuous working current, And the size of the current can be customized according to the actual needs of customers. The advantage of the pogo pin connector is that it has good elasticity and contractility, and plays an important role in the connection.

　　 Today I will introduce to you three reasons that cause the poor electroplating of pogo pins:

　　1, the color of the gold layer is abnormal

　　 Because the color of the gold-plated layer of the pogo pin connector is different from the normal gold layer, or because the color of the gold layer of different parts in the same accessory product is different.

　　2, the impact of raw material impurities

　　The impurity doped in the chemical material added to the plating solution will affect the color and brightness of the gold layer when it exceeds the tolerance range of the gold plating solution. If organic impurities still have the phenomenon of darkening and blooming of the gold layer, according to the experiment of the Haul slot test piece, the position of the darkening and blooming is not always the same. If metal impurities interfere, the effective range of current density will be reduced. The Haul tank test shows that the low end of the current density of the test piece is not bright, or the high end is not bright and the low end cannot be plated. Therefore, it is reflected in the plating part that the plating layer is reddish or even black, and the color change in the hole is more obvious.

　　3, the current density is too large

　　 Because there is an error in the calculation of the total area of ​​the plating bath parts, the value is larger than the actual surface area, so the plating current is too large. In addition, there is another reason, because the amplitude of the vibration is If it is too small, the crystals of all or part of the gold plating of the plating parts in the tank will be relatively rough, and the gold layer will appear red.
