PCB also has a golden color after gold plating, which is closer to gold, because gold is brighter and more beautiful than gold plating. For our customers, that is, what we provide to customers is a high-quality and comfortable feeling, and customers will be more satisfied with our products.
Therefore, its characteristics are summarized as follows.
1. Immersion gold plate has bright color, good color and beautiful appearance, which increases the attractiveness to customers.
2. The crystal structure formed by immersion gold is easier to weld than other surface treatments, with better performance and quality assurance.
3. Because there are only nickel and gold on the immersion gold board pad, the skin effect signal is transmitted on the copper layer, so it does not affect the signal.
4. Since there are only nickel and gold on the pads of the immersion gold board, the solder resist layer and the copper layer of the circuit are more closely combined, and micro-short circuit is not easy to occur.
Most manufacturers do not process immersion gold, so the welding is not good, so there are many complaints from customers. The flatness and atmospheric life of PCB circuit board immersion gold plate are as good as that of gold plate, so now most factories use immersion gold process to produce gold plate.
