Due to the high electrical performance requirements of the contact pair, the gold plating process holds an important place in the electroplating of spring loaded pin connections.

What issues should be addressed in spring loaded pin electroplating?

1. Surface treatment, such as electroplating, is often necessary to stabilize the functioning of spring loaded pins. Gold, platinum, rhodium ruthenium, palladium, nickel, silver, and other common electroplating metals include:

2. The gold-plating current density is too high: because the total area of the plating tank parts was incorrectly calculated, the value is greater than the actual surface area, causing the gold-plating current to be too high, or the amplitude of the gold-plating vibration is too small, causing all or part of the plating parts in the tank to fail. The gold plating layer's crystallization is rough, and the gold layer appears reddish.

3. The impact of impurities in gold-plating raw materials: When the impurities introduced by the chemical materials supplied to the plating solution exceed the tolerance of the gold-plating solution, the color and brightness of the gold layer are quickly affected. The gold coating will darken and bloom if it is contaminated with organic contaminants. The Hall cell test piece phenomena are black, and the flower's position is not fixed.

Analysis of potential issues in spring loaded pin connector electroplating

1. The gold layer's hue is unusual.

The color of the spring loaded pin connector's gold-plated layer differs from the color of the standard gold layer, or the color of the gold layer of different parts in the same supporting product differs.

2. The current density of gold plating is excessively high.

Because the total area of the parts in the plating tank was incorrectly calculated, the value is greater than the actual surface area, causing the gold plating current to be too large or the amplitude of the gold plating to be too small when vibration electroplating is used, causing all or part of the gold plating in the tank to be rough and visually impaired—redness in layers.
