Abstract: A thin conductive sheet having elongated openings extending inward from the edges to define a connecting arm extending from one end of one connecting surface to the diagonally opposite end of a second connecting surface. In one embodiment, the connecting arm extends directly from one corner to the diagonally opposite corner. In a second embodiment, the connecting arm changes direction to define a generally Z-shaped, reverse diagonal connecting path. Ties are provided across the elongated openings to hold the interconnector together during assembly, but which later break to permit the elongated openings to open up to define the connecting arm. One or more slits may be provided in the connecting arm to reduce buckling out of plane. The interconnector may be chrome plated in the central area to keep solder from flowing into the elongated openings and slits. To minimize the stress transition from the plated to the unplated portion, the plating terminates in a sine-wave-like wavy line which is 180.degree.
