Choice of Pogo Pin Surface Coating for TWS Products

TWS is the abbreviation of "TrueWirelessStereo". Intuitively, TWS headphones have no traditional physical wires. TWS earphones are equipped with a charging box, which can be stored or charged. The core charging component of TWS earphones and charging box is the PogoPin charging pins.

TWS earphones have special requirements for nickel release, sweat resistance, electrolysis resistance and salt spray resistance due to their constant contact with human skin and sweat. CFE has coating development engineers and develops a variety of special coatings, which can meet the special requirements of TWS industry.

The electroplating layer of TWS Pogo pin charging pins usually includes gold plating, silver plating, platinum plating, palladium plating and special composite coating, etc.

Different coating characteristics on the surface of Pogo pin:

1. Silverplating

Color: silver white

Good conductivity, low cost, no nickel release, long-term contact with the skin, commonly used for bracelets, smart watches.

2. Gold plating

Color: golden

It has strong corrosion resistance, wear resistance, electrical conductivity, high temperature resistance and beautiful appearance.

3.Platinumplating

Color: pure white

It has strong corrosion resistance, wear resistance, electrical conductivity, high temperature resistance,

the appearance is white to match the surface of the mechanism.

4. Palladium plating

Color: silver white

It has strong corrosion resistance, electrical conductivity, high temperature resistance, and wear resistance is stronger than gold, the appearance is beautiful match the surface of the mechanism.
