The crystal structure of immersion gold and gold plating is not a chemical structure, they are the structural form of a metal alloy. Both immersion gold and gold plating are processes that create crystal structures by depositing a layer of metal on a metal surface. These metal layers can be alloys composed of different metals, or they can be pure metal layers of a single metal.

The crystal structure of immersion gold and gold plating is formed by the interaction between metal atoms deposited on the surface of the substrate. These interactions can be achieved through overlapping electron clouds of the metals and chemical bonds between the metals. Therefore, the crystal structure of immersion gold and gold plating can be considered as a physical structure rather than a chemical structure.

The crystal structure of immersion gold and gold plating is a physical structure formed by the interaction between metal atoms, rather than a chemical structure.

1. The crystal structures formed by immersion gold and gold plating are different. The thickness of gold for immersion gold is much thicker than gold plating. Immersion gold will be golden yellow, which is more yellow than gold plating (this is one of the methods to distinguish gold plating and immersion gold). 1), the gold-plated one will be slightly white (the color of nickel).
2. The crystal structures formed by immersion gold and gold plating are different. Immersion gold is easier to weld than gold plating and will not cause poor welding. The stress of the immersed gold plate is easier to control, and for products with bonding, it is more conducive to bonding processing. At the same time, because immersed gold is softer than gold plating, gold fingers made of immersed gold plates are not wear-resistant (disadvantages of immersed gold plates).
