According to IPC-T-50: Printed Circuit Board - A printed board that provides both point-to-point connections and printed components in a predetermined arrangement on a common base. ( See also "Printed Wiring Board.")
Printed Wiring Board - A printed board that provides both point-to-point connections, but not printed components, in a predetermined arrangement on a common base. ( See also "Printed Circuit Board.") Printed Circuit Board Assembly - An assembly that uses a printed circuit board for component mounting and interconnecting purposes. Printed Wiring Board Assembly - An assembly that uses a printed wiring board for component mounting and interconnecting purposes. Therefore, according to the above, what most of us call pc boards are actually pw boards. Regards, Steve Smith Product Engineer Staco Energy Products Co.
