1. Because the crystal structure of sunken gold and gold plating is different, sunken gold will be more yellow than gold plating, and customers are more satisfied. 2. The project will not have an impact on the spacing when making compensation. 3. The flatness and life expectancy of the sunken gold circuit board is as good as that of the gold-plated board.

What checks need to be done during the production of Circuit Boards to reassure customers? Many customers in the selection of suppliers, will be worried about the quality of the problem. Today Wei Fu circuit board editor will share with you in the entire circuit board production proces

About the production of multilayer circuit boards, first of all, according to the functions that need to be achieved by electronic products, drawing circuit schematics, there are special drawing tools, it is like understanding the individual components with wires. Then, the PCB circuit board design software will generate a physical connection file based on the circuit schematic to connect all the components, the connection is very thin and thin copper skin in the actual producti
