Selective plating of Winding Wheel in Circuit Board

                          Selective plating of Winding Wheel in Circuit Board


          The pins and pins of electronic components, such as connectors, integrated circuits, transistors and flexible printed circuits, are selected to obtain good contact resistance and corrosion resistance.


          This kind of electroplating method can adopt the manual electroplating production line or the automatic electroplating equipment. It is very expensive to choose the plating for each pin individually so the batch welding must be adopted. In electroplating, the two ends of the metal foil that is rolled flat to the required thickness are usually punched and cleaned chemically or mechanically, and then selectively made of nickel, gold, silver, rhodium, knobs, or tin nickel alloys. Copper-nickel alloy, nickel-lead alloy and so on carry on the continuous electroplating.
