Why We Use Immersion Gold Board Process for PCB Board

Why We Use Immersion Gold Board Process for PCB Board
In order to solve the above problems of gold-plated boards, PCB using gold-plated boards mainly have the following characteristics.

1. Because the crystal structure formed by immersion gold and gold plating is different, immersion gold will be golden yellower than gold plating, and customers will be more satisfied.

2. Because the crystal structure formed by immersion gold and gold plating is different, immersion gold is easier to weld than gold plating, and will not cause poor welding and cause customer complaints.

3. Because the immersion gold board only has nickel and gold on the pad, the signal transmission in the skin effect is on the copper layer and will not affect the signal quality.

4. Because immersion gold has a denser crystal structure than gold plating, it is not easy to produce oxidation.

5. Because the immersion gold board only has nickel and gold on the pads, it will not produce gold wires and cause slight shortness.

6. 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 combined.

7. The project will not affect the distance during compensation.

8. Because the crystal structure formed by immersion gold and gold plating is different, the stress of the immersion gold plate is easier to control, and for products with bonding, it is more conducive to bonding processing. At the same time, it is precisely because the immersion gold is softer than the gilding, so the immersion gold plate is not wear-resistant as the gold finger.

9. The flatness and stand-by life of the immersion gold board are as good as the gold-plated board.
