Special Round Head Step Screw Production Flow
In addition, there are different roles depending on various plating needs. Examples are as follows:
1. Copper plating: used as a primer to improve the adhesion of the plating layer and the ability to resist corrosion. (Copper is easily oxidized. After oxidation, copper is no longer conductive, so copper-plated products must be protected by copper.)
2. Nickel plating: base or appearance, improve corrosion resistance and wear resistance, (where chemical nickel is more resistant to chrome plating in modern processes). (Note that many electronic products, such as DIN heads, N heads, no longer use nickel to make the base, mainly because nickel is magnetic, which will affect the passive intermodulation in the electrical performance)
3. Gold plating: Improve the conductive contact resistance and improve signal transmission. (Gold is the most stable and expensive.)
4. Palladium-plated nickel: Improve the conductive contact resistance, improve signal transmission, and wear resistance higher than gold.
5. Tin-plated lead: Improve the welding ability, and be replaced by other substitutes (because lead is mostly changed to bright tin and matte tin).
6. Silver plating: Improve the conductive contact resistance and improve signal transmission. (Silver has the best performance, is easy to oxidize, and is also conductive after oxidation)
Electroplating is a method of laying a metal layer on a conductor using the principle of electrolysis.
