Background

The printed circuit board is a basic component of various electronic products, and an important part in the production process is to etch away the extra copper (generally 60-70%) except for the circuit requirement on the copper foil plate by a chemical etching method. The acidic copper chloride and alkaline copper chloride etching solution are the most used etching agents at present, wherein the acidic copper chloride etching solution is particularly suitable for printed circuit board products with high etching precision requirements due to the characteristics of small side etching and the like, and is increasingly used by a large number of printed circuit board factories. The chemical reaction during etching is that one bivalent copper ion in the etching solution oxidizes one metal copper atom on the copper foil plate to generate two univalent copper ions. Therefore, as the etching proceeds, the total copper and monovalent copper ion concentration in the etching solution increases, which will cause the etching capability to gradually decrease. In order to maintain the desired etching capacity, it is common practice to chemically regenerate a portion of the etching solution by adding a chemical oxidizing agent to the etching solution to oxidize monovalent copper to divalent copper. The chemical reaction equation of the etching solution after chemical regeneration repeatedly using the etching reaction principle is as follows: CuCl2+ Cu → 2CuCl, the chemical reaction equation of the regeneration reaction principle is: 2CuCl +2HCl + H2O2 → 2CuCl2+2H 2O.
