Abstract
Abstract A printed circuit board contains a plurality of component contacts for receipt of electronic components and a plurality of electrically conductive traces, each trace being electrically connected to a corresponding one of the component contacts. A corresponding plurality of interconnect holes is formed on a selected portion of the printed circuit board with each interconnect hole contacting uniquely a corresponding one of the plurality of electrically conductive traces. A multiplicity of custom conductive traces are then formed in the interconnect region such that each of the multiplicity of conductive traces interconnects at least one of the interconnect holes to at least one other interconnect hole thereby to form an electrically conductive path between each of the interconnect holes interconnected by the custom conductive traces. A user is thus able to achieve a desired electrical function from the electronic components to be connected to the printed circuit board.
