  • Patent number: 4556145
    Abstract: A one piece carrier for flatpack chips capable of accommodating chips of varying size. The carrier includes a pair of cantilever arms each having a tapered head for holding chips of varying thicknesses. The arms extend into the carrier's central aperture, one from the top and one from the bottom side of the aperture. Longitudinally offset stops are mounted on the arms to both laterally and longitudinally stabilize a small chip whose length is insufficient to reach the conventional stops mounted on the top and bottom sides of the central aperture. A recess is provided in the lateral sides of the central aperture to accommodate motion of the cantilever arms so that chips of varying widths may be held between the heads of the arms up to the width of the central aperture. A step of lower elevation is formed in the body of the carrier between the lead support channels adjacent the lateral sides of the central aperture to accommodate the formed leads of a chip.
