1. The gilded circuit board is golden yellow, more yellow and more beautiful than the gilded circuit board;
2. Gold plated circuit board is more compact than gold plated crystal structure and is not easy to be oxidized;
3. Only the bonding pad of the gold plated PCB has nickel gold, which will not produce gold wire and cause slight shortness;
4. Only the pad of the gold plated PCB has nickel gold, and the bonding between the solder mask and the copper layer on the circuit is more firm;
5. Gold plating is softer than gold plating, so its abrasion resistance is not as good as gold plating. For gold finger board, the gold plating effect will be better.
6. Only the pad of the gold plated PCB has nickel gold, and the signal transmission in the skin effect will not affect the signal in the copper layer;
7. The crystal structure formed by gold deposition is different from that formed by gold plating, and the gold plated circuit board is easier to weld than the gold plated board, which will not cause poor welding;
