printed circuit board (PCB)

This term is defined in ECSS-Q-ST-70-08C as
product resulting from the process of selectively etching unwanted copper from one or both surfaces of a copper-clad insulating substrate to form a desired circuitry pattern which is subsequently solder- or gold-plated

This term is defined in ECSS-Q-ST-70-10C as
printed board that provides both point-to-point connections and printed components in a predetermined arrangement on a common base

This term is defined in ECSS-Q-ST-70-12C as
product resulting from the process of selectively etching unwanted copper from surfaces of copper clad insulating substrates to form a desired circuitry pattern which is metal-plated and laminated
