Electronic device composite plating
Composite plating development background: In the connector industry, pogo pin connection is a unique connector technology. This reliable technology is widely used in many electronic products, such as electronic cigarettes, mobile phones, chargers, antennas, POS machines, notebooks, headphones, magnetic interfaces, medical equipment, communication equipment, wearable devices, etc.
Pogo Pin Composite Plating
Especially sportswear products, which have wide application prospects and great demand, and often come into contact with the skin, will be exposed to a lot of sweat, and the fast charging current is large, which puts forward new requirements for the electrical performance and corrosion resistance of the products. At present, the traditional nickel plating gold process is increasingly unable to meet the development needs of customers, so a new electroplating process - a composite electroplating process that can meet the needs of customers has been developed.

Advantages and disadvantages of traditional nickel-gold plating and composite plating
Representative composite plating_The outermost layer is rhodium-plated ruthenium/platinum-plated
Reasons for choosing rhodium-plated ruthenium and platinum: Rhodium-ruthenium and platinum metals have high hardness, good wear resistance, and superior electrical conductivity. They are commonly used precious metal gold plating metals for contact plug-in connector plating, and platinum-based metals themselves are extremely high. Electrochemical corrosion resistance, this type of plating is more and more used in consumer products that require electrolytic corrosion.
