PRINTED CIRCUIT BOARD IEEE PAPER 2022


A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. PCB is a blank circuit board with no electronic components attached, while a PCBA is a completed assembly that contains all of the components required for the board to function as needed for the desired application. A PCB is not yet functional, while a PCBA is ready to be used in an electronic device.
