Plating Issues Of Hot Runner Sockets And Connectors

Heavy Duty Connector The color of the gold layer is inconsistent with the normal color of the gold layer, heavy duty connector 6 pin or the color of the gold layer in different parts of the same accessory product is different. The reason for this problem is:

1.heavy duty electrical contacts The influence of impurities in the gold plating raw materials

heavy duty industrial connector When the impurities brought in by the chemical substances added to the plating solution exceed the tolerance of the plating solution, heavy duty male female connector will soon affect the color and brightness of the gold layer. heavy duty multi pin connectors If affected by organic impurities, heavy connector will appear darkening and haloing of the gold layer, and the position of darkening and haloing is not fixed on the Hall slot test piece. heavy duty cable connectors If metal impurities interfere, the effective range of current density will be narrowed. The Hall slot test shows that the current density of the sample is not bright at the low end or the high end is not bright, and the low end is not plated. It is reflected in the redness or even blackening of the plating layer, and the color change in the hole is obvious.

2. The current density of gold plating is too high

Due to the calculation error of the total area of ​​the parts in the plating tank, its value is greater than the actual surface area, making the gold plating current too large, or the amplitude is too small when using vibration gold plating, making the gold plating layer in the tank all or partly crystallized and rough, and the gold layer is visually red.
