1. because the crystal structure formed by gold and gold plating is not the same, gold will be gold more yellow than gold plating, customers are more satisfied.

2. because the crystal structure formed by gold plating and gold plating is not the same, gold plating is easier to weld, will not cause poor welding, cause customer complaints.

3. because the gold plate only has nickel gold on the pad, the signal transmission in the skin effect is in the copper layer will not affect the signal.

4. because the crystal structure is denser than that of gold plating, it is not easy to produce oxidation.

5. because the gold plate only has nickel gold on the pad, it will not be produced into gold wire caused by short.

6. because the gold plate only has nickel gold on the pad, the welding resistance on the line is more firmly combined with the copper layer.

7. the project will not affect the spacing when making compensation.

8. because the crystal structure formed by gold plating and gold plating is not the same, the stress of the gold plating plate is easier to control, and it is more conducive to the processing of the

Bonding products. At the same time, because the sinking gold is softer than the gilding, the sinking gold plate is not wear-resistant to the goldfinger.

9. the flatness and service life of the gold plate is as good as that of the gold plate
