electroplating nickel copper tin is to treat the surface of the substrate before electroplating to provide good adhesion and corrosion resistance. The following is the general pre-plating treatment workflow:
1, surface cleaning: cleaning the dirt, grease, oxide and other substances on the surface of the substrate. Commonly used cleaning methods include alkali washing, acid washing, solvent cleaning, etc. Alkaline washing can remove grease and dirt, acid washing can remove oxides and oxide layers on metal surfaces, and solvent cleaning can remove some organic pollutants.
2. Surface activation: The activation treatment is to increase the reactivity of the substrate surface and improve the adhesion of the plating solution to the substrate. Commonly used activation methods include pickling activation, electrolytic activation, and the like. Acid wash activation is treated with an acidic solution, and electrolytic activation is treated with an electrolytic solution.
3, pre-plating treatment: according to the needs of electroplating nickel copper tin for appropriate pre-plating treatment. For example, a layer of nickel may be pre-plated prior to copper electroplating to increase the adhesion and corrosion resistance of the copper layer.
4. Rinse with clean water: Rinse the surface of the pretreated substrate with clean water to remove residual treatment agent and ions.
5. Drying: dry the surface of the rinsed substrate to avoid the influence of moisture on the electroplating process.

above is the general pre-plating workflow of electroplating nickel, copper and tin. The specific steps and methods may vary due to different processes and requirements. When pre-plating, it is necessary to strictly control the process parameters of each step to ensure the treatment effect and consistency to obtain good coating quality and performance.
