Why do PCB manufacturers use immersion gold plate technology

In order to solve the above problems of gold-plated circuit boards, PCB manufacturers using gold-plated PCBs 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 there is only nickel and gold on the immersion gold circuit board, the signal transmission in the skin effect is on the copper layer and will not affect the signal quality.
4. Because the crystal structure of immersion gold is denser than that of gold plating, it is not easy to produce oxidation.
5. Because the immersion gold pcb board only has nickel and gold on the pads, it will not produce gold wires and cause slight shortness.
6. Because the immersion gold pcb board only has nickel and gold on the pads, the solder mask on the circuit and the copper layer are more firmly bonded.
7. The project will not affect the spacing when making 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.
