Jan 16, 2020· Gold plating is the process of adding a thin layer of gold to another metal in order to give that metal a gold-like appearance. In most cases, the layer of gold is very thin, just enough to cover all exposed surfaces of the other metal. It is commonly used in decorations and in jewelry plating.
Quality control for hard gold finishes include thickness and tape adhesion tests. As you may expect, the price of gold requires solid process controls as the cost for errors are significant. The calculation to determine the amount of gold required is a function of the plating time.
With selective spot plating, Precious Plate will engineer gold, palladium, or silver plating processes to your specific plating needs, achieving significant savings over standard selective plating processes. We utilize the unique selective spot plating equipment designs provided by our sister company, Precision Process .
sulfite plating in the gold electroplating bin on the shelves. 2.2.3.1. Mergasin, et al (see citation at top of SOP) found the optimal process 2conditions for low stress to be 3.5 mA/cm and 58 oC. Stress was found to vary strongly with both parameters. You may need to experiment with the process parameters to achieve best results. 2.3. Gold plating
