A printed circuit board, or PCB, is used to mechanicallysupport and electrically connect electronic componentsusing conductive pathways,tracks or signal traces etchedfrom copper sheets laminated onto a non-conductivesubstrate. It is also referred to as printed wiring board(PWB) or etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA). Printed circuit boards are used in virtually all but the simplest commercially-produced electronic devices.
