The electroplating process refers to the whole process of applying the principle of electrolysis to deposit a layer of other metal materials or aluminum alloys on some metal surfaces. The processing technology has the functions of preventing air oxidation of metal materials (such as rust), improving wear resistance, electrical conductivity, light reflectivity, corrosion resistance (copper sulfate, etc.), and improving appearance.
The common surface coating types of pogo pins are: electroplating, nickel electroplating, gold plating, stainless steel, hot-dip galvanizing, barrel plating, etc.; different electroplating materials can consider different application requirements, just like comparing the current amount High ones are usually solved by surface plating. As we all know, the conductivity of gold at room temperature is the best metal material, followed by gold plating; in addition, some products will always be in contact with the skin (such as smart sports bracelets, wireless Bluetooth headsets), and must also be sweat-proof. There are special requirements such as corrosion, not very sensitive to the skin, etc., which imposes higher requirements on the electroplating process layer. In this way, the production cost of the pogo pin RF connector will be higher.
Some products will also choose to use basic electroplating materials such as electroplating nickel, gold plating, stainless steel, hot-dip galvanizing, etc. This product usually has a large volume, the current regulation is not particularly high, and the cost is relatively low, and such raw materials are usually selected. .
Finally, let's talk about plating. The raw materials for the production and processing of pogo pins are usually red copper, mainly because copper has good conductivity and suitable production and processing strength. And there are some unique products that use the key production and processing raw materials in stainless steel.
