A printed wire board is a board that houses circuit components with wires embedded on the surface of the board rather than discrete wires connecting individual circuit components. The original patent filers of the printed wire board imagined a future where wires would be able to be easily printed on the surface of circuit boards. This idea never came to fruition on a large scale.
