Shen Golden Board and Gold Placing Board are often used by PCB circuit boards. Many engineers cannot correctly distinguish between the two. Even some engineers believe that there is no difference in the two. This is a very wrong point that must be corrected in time. Next, I will talk about the difference between Shen and plated PCB line board.

     Everyone chooses gold plating, what is gold plating, what we call the whole plate gold plating, generally refers to "electroplating", "electroplating golden plate", "electrolyte", "electric gold", "electric nickel gold plate" The distinction between hard gold (generally hard gold is used for golden fingers). The principle is to dissolve nickel and gold (commonly known as gold salt) in chemistry, immerse the circuit board in the electroplating cylinder The copper foil surface generates nickel gold plating layers. Due to the high hardness of the coating, the abrasion resistance, the advantages of not oxidation are widely used in electronics.

     What is Shen Jin? Shen Jin generates a layer of plating layer through the method of reacting the reaction of chemical oxidation. Generally, the thickness of the chemical nickel gold layer deposition method can achieve a thick gold layer.
