A flexible asymmetrical jumper assembly is used to electrically join to circuit boards together where the geometry requires that the jumper be bent, often in a tight loop, so that the pads which form the ends of the jumper are parallel to each other. The jumper assembly contains two sets of wires, each set containing an array of foil fingers terminated in pads. The upper set of wires is bonded to the upper side of a central insulating sheet, while the lower set is bonded to the lower side of the central insulating sheet. An upper insulating sheet is bonded to the upper side of the upper set of wires, leaving the pads exposed for later soldering. A lower insulating sheet is likewise bonded to the lower side of the lower set of wires, with the pads also exposed. A hole is drilled through each upper pad, through the center insulating sheet, and into the corresponding lower pad. The holes are then through plated. The pads are of two different types, a major, or larger pad, and a minor, or smaller pad. The pads are disposed on the fingers such that each upper major pad is adjacent to a corresponding lower minor pad, and vice versa. As a result, the stress raisers created at the line where the upper insulator is bonded to the upper set of wires is offset from the stress raiser created at the line where the lower insulator is bonded to the lower set of wires.
