printed circuit - Computer Definition
An electrical circuit, generally of copper foil, printed on a substrate dielectric material. A sheet of copper foil is adhered to the substrate, and the unwanted portions of the foil are then removed by a process of silk screen printing, photoengraving, or mechanical milling.The remaining traces of copper foil form the circuit that connects components such as silicon chips mounted on the board. See also printed circuit board.
The interconnection of transistors and other electronic components via pathways made of copper or some other conductive material that is etched or laminated onto a rigid or flexible surface. The "printed" means that the material is deposited onto the substrate and that discrete wires are not used. The printed circuit stems back to the 1940s. See printed circuit board.
