We respond to the new demands of wearable and mobile devices.
In wearable and mobile devices, the required performance is becoming increasingly demanding, including durability and fast charging. The performance required for charging terminals and connectors (such as USB-C and pogo pins) cannot be met by conventional gold plating. When gold-plated terminals come into contact with seawater, pool water, sweat, or beverages during charging, corrosion occurs. By plating the contact terminals with RHODUNA-ALLOY 1, high resistance to corrosion can be achieved. This plating film is also compatible with fast charging of devices.
