Plated Gold Spring-loaded Pogo Pin

Plated gold Spring-loaded pogo pin

The pogo pin material is mainly made of copper, and the surface is required to be treated to make it have corrosion resistance and friction resistance. The typical surface treatment is gold plating after nickel plating and tin plating after copper plating. Below we will conduct a simple analysis on the surface treatment process of the connectors such as the electroplating process, equipment, products to be plated, and electroplating layer.

The pogo pin electroplating process is the same as the general electroplating process, but the operation time of each process is significantly shorter than that of general electroplating. Therefore, each treatment solution and plating solution must be adjusted accordingly to meet the requirements of short operating time.

Degreasing: Different from the general electroplating process, the degreasing time of the pogo pin is 2~5 seconds, so multi-stage electrolytic degreasing under high current density is used.

Pickling: Due to the size requirements of the metal to be plated, the pogo pin usually uses chemical or electrochemical polishing instead of self-dissolution of the metal.
