TWS Pogo pin charging contacts
TWS Pogo Pin Charging Contacts is the abbreviation of “True Wireless Stereo”. Intuitively, TWS earphones 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 Pogo pin 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 the 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 the TWS pogo pin charging contacts:
1. Silverplating
Color: silver white
Good conductivity, low cost, no nickel release, long-term contact with the skin, commonly used for bracelets and smart watches.
2. Gold plating
Color: golden
It has strong corrosion resistance, wear resistance, electrical conductivity, high temperature resistance, and a beautiful appearance.
3.Platinumplating
Color: pure white
It has strong corrosion resistance, wear resistance, electrical conductivity, and 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 that is stronger than gold; the appearance is beautiful, matching the surface of the mechanism.
