| titleOfInvention | Arsenic-contained sulfite cyanide-free plated gold electroplating liquid and electroplating method |
| abstract | The invention discloses arsenic-contained sulfite cyanide-free plated gold electroplating liquid and an electroplating method. The electroplating liquid comprises 10-15 g/L of gold trichloride calculated by gold, 78-94 g/L of sulfite calculated by sulfurous acid radical, 9-16 g/L of nitrophenol and 0.16-0.48 g/L of arsenic trichloride. The electroplating liquid uses the sulfite as a main coordination agent, the nitrophenol as a stable positioning agent, the arsenic trichloride as a brightening agent and the gold trichloride as gold main salt, so that the electroplating liquid is better in dispersibility and deep plating capacity, high in cathode current efficiency and excellent in plating liquid performance. A plating layer electroplated by the plating liquid under the alkaline condition is low in porosity, high in brightness and excellent in plating layer quality. |
