Project Description
PCB (Printed Circuit Board)
According to the circuit design, the electrical wiring connecting the circuit components is formed into a wiring pattern, and then the circuit board formed by recreating the electrical conductor on the insulator is performed by mechanical processing, surface treatment, or the like specified by the design.
The manufacturing process of the circuit board is to use the printing, photographic, etching and electroplating technologies to manufacture precision wiring, and to be an assembly base for supporting electronic parts and circuits between the parts. Therefore, the high-density and multi-layered wiring forming technology has become the mainstream of the development of the printed circuit board manufacturing industry.
It will appear in almost every electronic device. If there are electronic parts in a certain device, they are also mounted on different sizes of PCB.
