PCBÜ

abbreviation (Science and Technology) Short for printed circuit board, a flat sheet carrying the printed circuits and microchips in a microcomputer or other microelectronic device. Etymology: The initial letters of Printed Circuit Board. History and Usage: A common abbreviation in writing on computing and electronics since the seventies; it is now sometimes used in less technical sources and is included here to distinguish it from the commoner use above. If you look inside its workings, you will find the PCB (printed circuit board), with all the chips or ICs (integrated circuits), neatly plugged into it. Observer 3 Oct. 1982, p. 21
