1, gold layer connector color is not normal and normal color gold plating layer of gold color is inconsistent, or different parts of the same color appears gold layer ancillary products difference occurs because of this problem are:

2, impurities affect gilded raw materials when incorporated into a chemical bath impurities than gold plating solution will soon bear extent affect the color and brightness of the gold layer. If the organic impurities on the gold layer will appear dark and Flooding phenomenon, Hao Seoul groove specimen inspection dark and blur position is not fixed. if the interference is caused by metallic impurities current density effective range narrows, Hao Er cell test specimens show is not on the low end of the current density or high-end galvanized bright plating is not on the low end. is reflected in the red or black coating on the plating, the color change which bore obvious.

3, the current density is too large gilt plating tank parts total area calculation error value is greater than its actual surface area, so that excessive current gold-plated or gold plating when using vibration amplitude is too small, so that all or part of the plating bath gold plating crystallization rough visually gold layer red.
