There are the main features of the PCB using the gold-plated board.
Why use Immersion Gold
The crystal structure formed by immersion gold and gold board is different. Immersion gold will be golden yellow and yellower than gold board.The customers are more satisfied.
Immersion gold is easier to weld.It will not cause poor welding and cause customer complaints. The stress of the gold sink plate is easier to control.Because the gold sink is soft, the gold finger of the gold sink board is not wear-resistant.
Immersion gold board only has nickel gold on the pad, the signal transmission in the skin effect is in the copper layer and will not affect the signal.
Therefore, it will not produce gold wire and cause shortness. The combination of solder mask and copper layer on the circuit is stronger.
Immersion gold has a dense crystal structure and is not easy to produce oxidation.The flatness and service life of the immersion gold board are as good as the gold-plated plate.
Therefore, at present, most factories use the gold sinking process to produce gold board .
However, the immersion gold process is more expensive than the gold plating process, so there are still a large number of low-cost products that use gold board processes, such as remote control boards and toy boards.
