Connector application process
In wearable and mobile devices, charging speed and durability are important performance factors. However, gold-plated connectors can corrode when current flows while in contact with water or sweat containing minerals. To meet the high demands of the market, Yumicore proposes PLATUNA N 1. PLATUNA N 1 is a pure gold plating solution that produces a high-gloss, white appearance coating. The coating has excellent electrical properties, high wear resistance, and outstanding corrosion resistance.

Gold-plated connectors corrode when electric current flows while in contact with water or sweat containing minerals. Therefore, we propose PLATUNA N1 as a process for connector applications. Given the current market prices of metals, switching from other precious metals to platinum offers significant cost advantages. We also offer PLATUNA PT, which can be applied in thicker layers. We will suggest the most suitable platinum plating solution according to your application.
