Today let’s talk about the advantages of immersion gold.
1.The use of immersion gold manufacture PCB surface colour is very bright, good colour.
2.Immersion gold PCB formed by the crystal structure than other surface treatment of the PCB is easier to weld, can have a better performance, to ensure the quality of the PCB.
3. Because the immersed gold PCB only in the pad with nickel gold, will not have an impact on the signal, because the skin effect in the transmission of the signal is in the copper layer.
4. The metal properties of gold is more stable, the crystal structure is more dense, not easy to oxidation reaction.
5. Because the immersed gold plate only pads on the nickel gold, so the line solder resist and copper layer of the combination of more solid, but also not easy to cause micro-short circuit.
6. The project will not have an impact on the pitch when making compensation.
7.The use of immersion gold manufacture of the PCB stress is easier to control.
