AC-1 Single Component Acid Copper Brightener Electroplated thick copper Electroformed copper
Properties
AC-1 single component acid copper brightener is a high-performance single component acid copper plating brightener developed by our company for continuous copper plating on electroformed copper, coil to coil, and high acid low copper electroplating processes. Its leveling, throwing, and temperature resistance performance have reached the highest level of similar products. Its process characteristics are as follows:
1. Good leveling and excellent dispersion performance in low current density areas;
2. It does not contain organic dyes and has low internal stress in the coating;
3. High current density areas are not easy to ignite;
4. All imported intermediates are used, with high purity, few decomposition products, and stable plating solution;
5. Suitable for various processes such as electroforming copper, continuous copper plating on coils, high acid and low copper electroplating, etc;
6. Single component formula, low consumption, and low cost;
7. The process is very stable, easy to operate and maintain, and can last for up to six months without the need for major adjustment.
