Printed board manufacturers have a lot of surface treatments when they produce PCB boards. What is the difference between your science and gold plating?
1. When printed circuit board manufacturers produce PCB circuit boards, the crystal structure formed by immersion gold and gold plating is different. The thickness of gold plating is much thicker than that of immersion gold. The gold plating will be yellower than gold, and the customer will be more yellow. satisfaction.
2. PCB board produced by printed board manufacturers is easier to solder than gold plating, which will not cause poor soldering and cause customer complaints. The stress of the immersion gold plate is easier to control, and it is more conducive to the processing of the bond for the bonded products. At the same time, because Shenjin is softer than gold plating, the gold plate is not wearable.3. The PCB board produced by the printed board manufacturer has only nickel gold on the pad. The signal transmission in the skin effect is not affected by the signal in the copper layer.
The difference between the gold plate and the gold plating of printed board manufacturers
In the previous section, the first three points of the difference between the surface of the PCB board and the gold-plated board produced by the printed board manufacturers, today we will look at the following points.
1. PCB board produced by printed board manufacturers is more dense than gold plating, and it is not easy to produce oxidation.2. The PCB board produced by the printed board manufacturer has only nickel gold on the pad, so the solder joint on the line is more firmly combined with the copper layer. The project does not affect the spacing when making compensation.
3. PCB boards produced by printed board manufacturers are getting denser and denser, and the line width and spacing have reached 3-4 MIL. Gold plating is prone to shorts in gold wire. The gold plate has only nickel gold on the pad, so it will not produce a gold wire short circuit.
4, printed circuit board manufacturers of PCB circuit boards are generally used for relatively high requirements of the board, flatness is better, generally use Shen Jin, Shen Jin generally does not appear after the black pad phenomenon. The flatness and standby life of the immersion gold plate are as good as the gold plate.
