PCBs using immersion gold boards have the following main features [Copy link]

1. Due to the different crystal structures formed by immersion gold and gold plating, immersion gold will be golden yellow, which is yellower than gold plating, and customers are more satisfied. 2. Due to the different crystal structures formed by immersion gold and gold plating, immersion gold is easier to weld than gold plating, and will not cause poor welding and cause customer complaints. 3. Since there is only nickel gold on the pad of the immersion gold board, the signal transmission in the skin effect is on the copper layer and will not affect the signal. 4. Since the crystal structure of immersion gold is denser than that of gold plating, it is not easy to produce oxidation. 5. Since there is only nickel gold on the pad of the immersion gold board, it will not produce gold wire to cause micro short. 6. Since there is only nickel gold on the pad of the immersion gold board, the solder mask on the circuit is more firmly combined with the copper layer. 7. The project will not affect the spacing when making compensation. 8. Due to the different crystal structures formed by immersion gold and gold plating, the stress of the immersion gold board is easier to control, which is more conducive to the bonding process for products with bonding. At the same time, because immersion gold is softer than gold plating, the immersion gold board is not wear-resistant for gold fingers. 9. The flatness and service life of the immersion gold board are as good as those of the gold-plated board.
