What does an electroplating factory do?

Electroplating is a process of depositing a thin layer of metal, alloy or composite material on the surface of conductive solid by electrochemical method, which is a special electrolytic process.

Electroplating is to connect the parts or substrate to be plated with the negative electrode of electroplating power supply, connect the metal or insoluble conductor with the positive electrode of electroplating power supply, use the solution containing the metal ions to be plated as electrolyte, and control the appropriate process conditions after turning on the power supply, so that the metal, alloy or composite material to be plated can be deposited and precipitated on the negative electrode.

According to the functional requirements of various electroplating

1, copper plating: used as primer to improve the adhesion and corrosion resistance of electroplated layer.

2. Nickel plating: used as primer or appearance to improve corrosion resistance and wear resistance.

3. Gold plating: improve conductive contact impedance and enhance signal transmission.

4. Pd-Ni plating: improve the conductive contact impedance and enhance the signal transmission, and the wear resistance is higher than that of gold.

5. Tin and lead: improve welding ability.

6. Silver plating: improve conductive contact impedance and enhance signal transmission.
