| titleOfInvention | A kind of cyanide-free gold electroplating formula applied to wafer level packaging and its gold electroplating process |
| abstract | The invention discloses a cyanide-free gold electroplating formula for wafer level packaging and a gold electroplating process, including the preparation, formulation and electroplating process of gold salt. The formula includes components with the following mass concentrations: gold salt 1-20g/L, accelerator 10-15mg/L, composite complexing agent 4-24g/L, composite stabilizer 30-90mg/L, antioxidant 15-45mg/L L, dispersant 30-60mg/L, and plating agent 10-60mg/L. The gold coating obtained by the invention not only has bright gold, no chromatic aberration, the coating is dense and smooth, but also has excellent stability of the gold cylinder, which can prevent turbidity and discoloration within half a year, and the substances used in this product are all environmentally friendly chemical reagents. |
