What is the electroplating process?
The pogo pin, or pogo pin, refers to a high-precision radio frequency connector whose function is to connect current or data signals. The following explains the technical aspects of the surface coating of the pogo pin.
The electroplating process refers to the whole process of applying the principle of electrolysis to inlay a layer of other metal materials or aluminum alloys on the surface of some metals. It uses the effect of electrolysis to make the outer surface of metal materials or other raw materials adhere to a layer of ceramic film. The processing technology thus has the functions of preventing air oxidation of metal materials (such as rust), improving wear resistance, electrical conductivity, light reflection, corrosion resistance (copper sulfate, etc.), and improving aesthetics.
The common surface coating types of pogo pins are electroplating, electroplating nickel, gold plating, stainless steel, hot-dip galvanizing, barrel plating, etc.; different electroplating materials can consider different application requirements, just like comparing the current volume regulations High surface plating is usually used to solve it. As we all know, the conductivity of gold at room temperature is the best metal material, followed by gold plating; in addition, some products are always in contact with the skin (such as smart sports bracelets, wireless Bluetooth headsets), and must be protected from sweat. Special requirements such as corrosion, not being very sensitive to the skin, etc., have higher requirements for the electroplating process layer. In this way, the production cost of the pogo pin radio frequency connector will also 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 volume is not particularly high, and the cost is relatively low. Usually, such raw materials are selected.
Finally, I will talk about plating. The raw material for pogo pin production and processing is usually copper, mainly because copper has good electrical conductivity and suitable production and processing strength. And there are some unique products that use key production and processing raw materials among stainless steel plates.
