Why use immersion Gold? | China PCB manufacturing
Why use immersion Gold? | China PCB manufacturingThe use of immersion gold PCB mainly has the following characteristics
1. Due to the immersion gold and gold-plated crystal structure is not the same, the immersion gold will be golden, and It's more yellow than gold-plated. Customers will be more satisfied.
2. Immersion gold is easier to solder than gold-plated, does not cause poor soldering, cause customer complaints.
3. The immersion gold PCB only has nickel gold on the pad. Transmission of signal in skin effect is in the copper layer and it doesn't affect the signal.
4. The crystal structure is more compact and not easy to produce oxidation for immersion gold.
5. Because the immersion gold PCB only has nickel gold on the pad ,so will not produce a golden wire that will cause a little short.
6. The combination of solder mask on circuits and copper layer is more firmly.
7. It does not have an effect on the spacing when making compensation by engineer.
8. The stress of the immersion gold board is easier to control. For bonding products, more conducive to the processing of bonding.
9. The smoothness of the immersion gold PCB and the service life are as good as the gold-plated PCB.
