Abstract

A printed circuit board is provided with a pair of parallel foil conductive strips on one side thereof coupled by means of a conductive foil jumper adjacent and generally parallel to an edge of the circuit board. In this configuration, the two conductive strips are coupled in circuit by means of the foil jumper. An inner portion of the circuit board is provided with an aperture positioned interiorly on the circuit board relative to the foil jumper and adjacent thereto. The portion of the circuit located between the parallel foil conductive strips and between the aperture and the edge of the circuit board and upon which the foil jumper is positioned is detached from the circuit board electrically decoupling the parallel foil conductive strips. With the foil jumper thus removed, a connector may then be positioned on the edge of the circuit board in contact with the foil conductors for coupling an associated electronic device in circuit therebetween for processing of the signal carried by the foil conductors. The aperture includes a first pair of spaced stress concentrators directed toward the edge of the circuit board. A second pair of spaced stress concentrators aligned with the first pair in the form of slots are provided on a second side of the foil jumper on the edge of the circuit board to facilitate the breaking away and removal of that portion of the circuit board between the foil conductive strips and upon which the foil jumper is positioned.
