why do we need the immersion gold pcb board

In order to solve the above problems of gold-plated plate, PCB with sinkboard has the following characteristics:

1. Unlike the crystal structure formed by gold and gold plating, heavy gold is more yellow than gold, and customers are more satisfied.

2. Unlike the crystal structure formed by gold plating and gold plating, heavy gold is easier to weld than gold plating, which does not cause welding problems and causes customer complaints.

3. The transfer of signal in the skin effect is not affected by the signal in the copper layer.

4. The crystal structure is more compact and less prone to oxidation due to gold plating.

5. Because the sink plate only has nickel gold on the solder plate, it will not produce gold wire for short.

6. Because the gold plate only has nickel in the welding plate, the resistance welding on the line is stronger than the copper layer.

7. The engineering will not affect the spacing when making compensation.

8. Due to the different crystal structure formed by the gold and gold plating, the stress of the gold plate is easier to control, which is more conducive to bonding process for the products of the state.It is also because the gold is softer than the gold plating, so the gold finger is not wear-resistant.

9. The flatness of the sunken gold plate is as good as the gold-plated plate.
