　　1. Generally, the thickness of the gold is much thicker than the gold plating. The Shenjin Club is golden yellow than golden plating. It is more satisfied with Shen Jin on the surface customers. The crystal structure formed by the two is different.

　　2. Because the crystal structure formed by Shen Jin and the gold plating is different, Shen Jin is more likely to welded than gold plating, which will not cause poor welding and cause customer complaints. At the same time, because of the softering gold plating, the golden fingerboard is generally selected for gold, hard gold and wear -resistant.

　　3. Sinking golden board only has nickel gold on the pad, and the transmission of signals in the skin -tech effect will not affect the signal in the copper layer.

　　4. Sinking gold is more dense than gold plating, and it is not easy to produce oxidation.

　　5. As the wiring becomes more and more dense, the width and spacing have reached 3-4mil. Gold plating is prone to golden silk short circuit. The Shen Jin board only has nickel gold on the pad, so it will not produce gold silk short circuit.

　　6, the golden board only has nickel gold on the pad, so the combination of welding resistance on the line and the copper layer is stronger. The project will not affect the spacing when compensation.

　　7. It is generally used for relatively high -demanding boards. The flatness is better. Generally, Shen Jin is used. Shen Jin generally does not have the black pads after assembly. The flatness of the Shen Jin board is as good as the life -long life.

　　The above is the difference between Shen Jin board and gold -plated board. Now the price of gold on the market is expensive. In order to save costs, many manufacturers are no longer willing to produce gold -plated boards. A lot cheap. I hope this introduction will provide reference and help to everyone.

　　1. Shen Gold Board and Chemical Gold Board are the same process products. Electric gold boards and flash gold boards are also the same process products. In fact, they are just different names of different people in the PCB industry. The mainland peers are titled, and the golden board and the glittering gold board are more common in Taiwan.

　　2. Sinking gold board/chemical board is generally relatively formal name is chemical nickel gold board or nickel -moc -immersed gold board. The growth of the nickel/gold layer is plated in a chemical deposition; gold and gold board/flash gold The plate is generally relatively formal called nickel -plated golden board or flash gold -plated board. The growth of the nickel/gold layer is plated on the way of DC electroplating.
