PCB manufacturer why use heavy gold plate process

by:Rocket PCB     2020-08-01
PCB manufacturer to solve the problem of gold-plated circuit board of the above, the use of gold board PCB basically has the following features: 1. Crystal structure formed by the heavy gold and gold-plated, zedoary will are golden more yellow than a gold-plated, customers more satisfied. 2. Crystal structure formed by the heavy gold and gold-plated, zedoary more easily than a gold-plated welding, won't cause bad welding, cause customer complaints. 3. Because of the heavy gold PCB only nickel gold bonding pad, skin effect in the signal transmission in copper layer will not have an impact on signal quality. 4. Because of the heavy gold crystal structure more compact than a gold-plated, not easy to oxidation. 5. Only because of the heavy gold PCB welding plate nickel and gold, so will not produce micro short into gold. 6. Only because of the heavy gold PCB welding plate nickel and gold, so on a line of resistance welding and copper layer combining with stronger. 7. Engineering did not compensate on impact on spacing. 8. Of crystal structure formed by the heavy gold and gold-plated, its stress is easier to control heavy gold plate, with the state of products, is more advantageous to the state of processing. At the same time, it is because of heavy gold than gold plated soft, so heavy gold plate do gold finger not wear-resisting. 9. Heavy gold plate of smoothness and inactive life just as good as gold plated board.
are present in just about every facet of modern life.
