Surface coating treatment technology of spring Pogo Pin
What is a pogo pin? I believe everyone already knows that. It is a connector whose function is to connect current or signals. Today, we will mainly introduce the surface coating treatment technology of pogo pins.
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is the process of attaching a layer of the metal film to the surface of metal or other materials using electrolysis to prevent metal oxidation (such as corrosion), improve wear resistance, electrical conductivity, light reflection, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.
Common types of surface coatings for pogo pins include gold plating, nickel plating, silver plating, chrome plating, zinc plating, copper plating, etc. Different plating materials can meet different application requirements. For example, gold plating is often used where current requirements are high. Gold is known to have good electrical conductivity at room temperature, followed by silver plating. At the same time, some products are in direct contact with the skin (such as smart bracelets and Bluetooth earphones), and also require special requirements, such as anti-sweat corrosion and skin insensitivity. We have mastered this technology and have successfully applied it to a variety of products. Higher requirements are placed on the electroplating layer. However, the relative product cost of the pogo pin connector is also relatively high.
Other products will choose to use conventional plating materials, such as nickel plating, silver plating, chrome plating, zinc plating, etc. These products are generally large in size, with low requirements and relatively low cost, and this material is generally selected.
Copper-plated, the processing material of the spring thimble is usually brass. Brass has good electrical conductivity and moderate machining hardness. However, some special products use stainless steel as the main processing material, and copper plating is relatively rare, so it will not be described in detail here.
