In order to solve the above problems of gold -plated boards, the PCB of the Shen Golden Board mainly has the following characteristics:
1. Different from the crystal structure formed by Shen Jin and gold plating, Shenjin will be more yellowish than golden plating, and customers are more satisfied.
2. Different from the crystal structure formed by Shen Jin and gold -plated, Shen Jin is more likely to welded than gold plating, which will not cause poor welding and cause customer complaints.
3. Because there is only nickel gold on the pad on the pad, the transmission of the signal in the skin -tech effect will not affect the signal in the copper layer.
4. Because Shen Jin is more dense than gold plating, it is not easy to produce oxidation.
5. Because the golden board only has nickel gold on the pad, it will not produce golden wires and cause slight shortness.
6. Because the sinking gold board only has nickel gold on the pad, the combination of welding resistance and copper layer on the line is stronger.
7. The project will not affect the spacing when compensation.
8. Different from the crystal structure formed by Shen Jin and gold -plated, the stress of the Shen Jin board is easier to control, and it is more conducive to the processing of the state. At the same time, it is because Shen Jin is softer -plated, so Shen Jinban does golden fingers is not abrasion.
9. The flatness of the Shen Jin board is as good as the life expectancy.
