In order to solve the above problems of the gold -plated circuit board, PCB manufacturers use the PCB of the golden board mainly to have the following characteristics:

1. Different from the crystal structure formed by Shen Jin and gold -plated, Shenjin will be golden yellow 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 the golden line board only has nickel gold on the pad, the transmission of the signal in the skin -tech effect is that the copper layer will not affect the signal quality.

4. Because Shen Jin is more dense than gold plating, it is not easy to produce oxidation.

5. Because the Shenjin PCB board only has nickel gold on the pad, it will not produce golden wires.

6. Because the Shenjin PCB board only has nickel gold on the pad, the combination of welding resistance and the 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. For the products with Bangding, it is more conducive to the processing of the state. At the same time, because Shen Jin is softer, Shen Jinban does not wear golden fingers.

9. The flatness of the golden board is as good as the life expectancy.
