In the surface treatment of circuit boards, there is a very common process called gold deposition. The gold deposition process involves depositing a nickel gold coating with stable color, good brightness, flat coating, and good solderability on the surface of PCB printed circuits. PCB also has a golden yellow color after gold deposition, which is closer to gold because the color of gold deposition is brighter and more beautiful than that of gold plating. Next, Shenzhen Fusheng Yuncheng Technology Co., Ltd. will introduce the four major characteristics of PCB sinking technology to everyone.

Four Characteristics of PCB Gold Deposition Process

1. The sunken gold plate has a bright and beautiful color, which enhances its appeal to customers.

2.Compared with other surface treatments, the crystal structure formed by gold deposition is easier to weld, has better performance, and ensures quality.

3. Since there are only nickel and gold on the pad of the gold plated plate, the signal of skin effect is transmitted in the copper layer, so it will not affect the signal.

4. Due to the fact that there is only nickel and gold on the solder pad of the sinking gold plate, the solder resistance layer of the circuit is tightly bonded to the copper layer, making it less prone to micro short circuits.

The flatness and atmospheric life of PCB gilded plates are the same as that of gilded plates, so most factories now use the gilded process to produce gilded plates.
