Funzjoni: All kinds of coatings have a common benefit: they can prevent corrosion (increase antioxidant capacity) and play a decorative role.
Ram nikil plating: After electroplating, it has good chemical stability when working in the atmosphere and alkali solutions. It not easy to change color. It is oxidized above 600 degrees Celsius. It has high hardness and is easy to polish. The disadvantage is porosity. The surface of nickel plating looks brighter. Use It feels smooth to the touch. It has relatively strong adhesion and wear resistance.
Ram landa plating: It has high chemical stability, is kważi insolubbli in dilute solutions of sulfuric acid, nitric acid, nitric acid, and hydrochloric acid, and has good welding performance. Tin plating can prevent electromagnetic interference. Tin-plated ones look white and not that nice, and there be a layer of dark gray tin foam when touched by hand.
Usage occasions: Depending on the usage occasion, choose nickel plating or tin plating process. 1. If it is an exterior component, nickel plating is generally chosen, as it is smooth and beautiful and will not discolor after high-temperature testing. 2. If strong conductivity is required, the surface of the copper bar should be tin-plated. 3. If it is an internal komponent, tali bħal the EMI shield on the PCB board, tin plating (barrel plating) is magħżula, u xi wħud even have the bottom layer plated with nickel first and then tin plating.
