Copper plated circuit board is a circuit board that is coated with a layer of copper on a substrate to form a circuit pattern. Copper plating process is one of the key steps in manufacturing PCBs, which forms fine circuit patterns on the substrate to achieve electrical connections between electronic components.

　　In the copper plating process, electroplating or chemical plating methods are usually used. Electroplating is the process of depositing copper ions onto a substrate through an electrolytic cell, while chemical plating utilizes chemical reactions to form a copper layer on the surface of the substrate. Regardless of the method, precise control of process parameters is required to ensure the uniformity of the copper layer and the accuracy of the circuit.

　　Copper plated circuit boards are widely used in various electronic devices, including computers, communication equipment, consumer electronics products, and automotive electronic systems. Its superior conductivity and mechanical properties make it one of the fundamental materials in modern electronic industry.
