What Does Printed Circuit Board (PCB) Mean?
A printed circuit board (PCB) is an electronic circuit used in devices to provide mechanical support and a pathway to its electronic components. It is made by combining different sheets of non-conductive material, such as fiberglass or plastic, that easily holds copper circuitry.
Techopedia Explains Printed Circuit Board (PCB)
A PCB works on the copper films/assembly/circuit that are placed inside of it to provide a pathway for the flow of current. A PCB can hold various electronic components that may be soldered without using visible wires, which facilitates its use.
