Embodiment 1
[0023] The electroplating process of the automobile central control in this embodiment, the electroplating process includes the following steps:
[0024] (1) Pre-treatment: degreasing, roughening, reduction, pre-soaking, activation, degumming and electroless nickel plating are performed on the injection-molded automotive central control in sequence;
[0025] (2) Pre-nickel plating: Send the pre-treated automobile central control into the pre-nickel plating tank for pre-nickel plating treatment, and then put it into the cleaning tank and rinse it with pure water; the pre-plating solution in the pre-nickel plating tank It is a mixed solution of 250g / L nickel sulfate, 40g / L nickel chloride and 40g / L sulfuric acid, the pH value of the pre-plating solution is controlled at 4.4, the temperature is 60°C, and the pre-plating time is 3.5min;
[0026] (3) Copper replacement: Send the pre-nickel-plated car central control into the copper replacement tank for copper replacement. The coppe...
