Printed circuit boards (PCBs) shape the backbone of all significant electronics. These miraculous inventions pop up in almost all computational electronics, including less difficult devices such as digital clocks. For the uninitiated, a PCB routes electrical signals through your electronics, which fulfills the device's electrical and mechanical circuit necessities. In short, PCBs tell the electricity where to go, breathing life into your electronics. PCBs are most often green but they can come in any color.
A printed circuit board (PCB) is a thin board made by joining different sheets of non-conductive material like fiberglass, composite epoxy, plastic or other laminate material that easily holds copper circuitry. The conductive pathways are etched or “printed” onto the board, connecting different surface-mounted and socketed components on the PCB, such as transistors, resistors, and integrated circuits (IC).
PCBs manufacturing first requires designing the board with CAD tools and then fabricating it through several chemical operations.
The PCB manufacturing process can be accomplished in a variety of ways and there are various variations. In spite of the numerous little varieties, the main stages in the PCB manufacturing process are the same.
