Abstract

This method is for adding circuit wiring to printed circuit cards and printed circuit boards in the form of wire jumpering. The predetermined wiring pattern information is prepared in automated data form and introduced into a printed wiring generator or the like which functions to produce the circuit pattern artwork. The artwork is then used to expose a copper foil which resides on a thin flexible film or material. The latter can have wiring on one or both sides with circuit lands and plated through-holes as required by the predetermined pattern. The wiring surfaces are then covered with a coating of insulation except where the lands and plated through-holes occur.

Adding Circuit Wiring to Circuit Cards and Boards

This method is for adding circuit wiring to printed circuit cards and printed circuit boards in the form of wire jumpering. The predetermined wiring pattern information is prepared in automated data form and introduced into a printed wiring generator or the like which functions to produce the circuit pattern artwork. The artwork is then used to expose a copper foil which resides on a thin flexible film or material. The latter can have wiring on one or both sides with circuit lands and plated through-holes as required by the predetermined pattern. The wiring surfaces are then covered with a coating of insulation except where the lands and plated through-holes occur. The finished product provides an insulated, flexible and thin, eight to ten mils, printed wiring element which is usable to replace the commonly used individual wire jumpers.
