Abstract: A carrier having a plurality of leads extending from the lateral sides thereof. The leads extend along the lateral side and over protuberances into depressions in the bottom of the carrier. Each of the depressions is separated by ribs from the other depressions. The ends of the leads disposed in the depressions are prevented from substantial movement by the rib to prevent contact with adjacent leads. At least some of the leads are provided with holes disposed adjacent to the exit of the leads from the enclosure of the carrier. The holes in the leads allow the leads greater flexibility at their portions close to the entrance of the leads into the enclosure. The leads are tapered along their length toward the protuberances. Further, the leads are separated by a width along the lateral side which is within the range of substantially the width of the leads to less than the width of the leads to prevent nesting.
