Immersion gold uses a chemical deposition method, which generates a layer of plating through a chemical oxidation-reduction reaction method. It is a kind of chemical nickel-gold layer deposition method, which can reach a thicker gold layer.
There are the advantages of using immersion gold circuit boards.
Immersion gold board is bright in color, good in color and attractive in appearance.
The crystal structure formed by immersion gold is easier to weld than other surface treatments.There is better performance and ensure quality.
Because the immersion gold board only has nickel and gold on the pad, it will not affect the signal. The signal transmission in the skin effect is on the copper layer.
The metal properties of gold are relatively stable, the crystal structure is denser, and oxidation reaction is not easy to occur.
Because the immersion gold board only has nickel and gold on the pads, the solder mask on the circuit and the copper layer are more firmly bonded, and it is not easy to cause micro short circuits.
The project will not affect the distance during compensation.The stress of the immersion gold plate is easier to control.
