| titleOfInvention | A neutralizing reducing agent for post-treatment of PCB degumming |
| abstract | The invention discloses a neutralizing reducing agent for post-treatment of PCB degumming, which belongs to the field of printed circuit boards and is used in the degumming process of printed circuit boards. The neutralizing reducing agent in the post-treatment of PCB degumming contains sulfuric acid 20‑100g/L, hydrogen peroxide 5‑30g/L, hydrogen peroxide stabilizer 0.1‑1g/L, corrosion inhibitor 0.01‑0.1g/L, surfactant 0.1‑2g/L L; The advantage of the present invention is that the neutralizing agent has strong neutralizing and reducing ability, can effectively remove permanganate, manganate, manganese dioxide and other residues in blind holes and through holes, and at the same time has a negative effect on the charge of the hole wall. With pre-adjustment function, it can be used for horizontal and vertical degumming lines, with extremely low copper corrosion rate, low ammonia nitrogen content in wastewater, and easy sewage treatment. |
