Detailed explanation of pogopin connector electroplating process

Pogopin connector is a common precision connector, which is often used in lightweight and small portable electronic devices. Electroplating process is often used for its surface coating treatment.
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of some metals by using the principle of electrolysis. It can prevent oxidation (such as corrosion), improve wear resistance, conductivity, reflection, corrosion resistance and beauty for metal products.
The common surface coatings of pogopin connectors include: gold plating, nickel plating, silver plating, chromium plating, zinc plating, copper plating, etc; Different electroplating materials can meet different application needs.
For those with high current requirements, gold plating is generally used because gold is the metal with the best conductivity at room temperature. Silver plating is also very common. Some products are in direct contact with the skin (such as smart bracelets and Bluetooth headsets). They also need special requirements such as anti sweat corrosion and non sensitization to the skin. The product cost of pogopin connector will also be higher. Some products will choose to use conventional electroplating materials such as nickel plating, silver plating, chromium plating and zinc plating. These products are generally large in volume, not very high in current requirements and relatively low in cost.
