3). Gold is applied to the circuit board surface treatment, because of the strong conductivity of gold, good oxidation resistance, long life, general application such as button plate, goldfinger plate, etc., and the most fundamental difference between gold-plated plate and sink gold plate is th...
Gold-plated PCB boards are made by electroplating a layer of gold on the surface of PCB circuit board pads, which are made of hard gold. The principle is to dissolve nickel and gold in a chemical solution,immerse the circuit board in an electroplating cylinder, and connect an electric curren...
Gold plating refers either to the thin layer of gold that covers the surface of gold-plated items or to the process through which this coating is applied. The core of such pieces can be made of a variety of non-gold metals, and the gold with which they are covered can be of different...

“Gold Plate,”“Gold Plated,”“Gold Overlay,”“Rolled Gold Plate,”“Rolled Gold Plated,” or an adequate abbreviation, when such plating constitutes at least 1/40th of the weight of the metal in the entire article and when the term is immediately preceded by a designation of the karat...
An item labeled "G.P" is gold-plated. Similarly, jewelry labeled "G.F" is gold filled, which essentially means that it has a thicker layer of gold-plating. In some cases markings are followed by the name of a country. For example, "750 Italy". This indicates the gold item's ...
Good Conductivity: Gold is an excellent conductive material with low resistance and high conductivity. By plating gold on the surface of the metal connectors and pads of the circuit board, the contact resistance can be significantly reduced and the electrical conductivity of the circuit can be impro...
