MCCB Highlights
Advantages for MCCB Electronic type
Welding process flow of hardware parts
1. Copper material-punching and forming-pickling-surface treatment/electroplating of copper parts-welding
2. Our after-sales rate of copper electroplating does not exceed 3 in 7 years
After degreasing agent, pickling, cleaning, silver plating (the printing plate is converted into silver molecules by electrolysis, and then adsorbed on the copper by electrodes), cleaning, drying, drying at 100 ℃ and other processes, the following parts are obtained
3. Our copper electroplating silver content is up to 99.9999999%.
4. Through 7.5% potassium sulfide experiment, the time can be as long as 15 minutes, it solves the defects of unstable welding and discoloration of copper parts in the same welding process. The function is to ensure that the electroplated coating does not blacken and discolor within the specified time
