All signals are transmitted through the gold finger. Because its surface is gold-plated and the conductive contacts are arranged like fingers, it is called "gold finger". The gold finger board needs to be gold-plated or immersing gold; because gold has extremely strong oxidation resistance and strong conductivity; Application No. CN202021837132.7 proposes a gold-plating device for gold fingers of a printed plug circuit board. By adjusting the voltage coarse adjustment switch and the voltage fine adjustment switch, the voltage of the gold-plating pen and the negative pole is adjusted, thereby adjusting the gold plating thickness of the gold-plating pen on the gold finger, which is used to save the cost of materials and make the use of materials more controllable; however, the spacing distribution of different gold fingers is different, and the spacing of several gold-plated pens of the above-mentioned gold-plating device is not adjustable, and it cannot be suitable for gold plating of gold fingers with different spacing sizes; therefore, a gold-plating device for a printed circuit board plug is proposed.
