Abstract:
A leadframe comprising:a plurality of metal leads, each lead including an inner end segment beginning at an inner end of the lead; a nonconductive layer on the inner end segment of at least one of the leads; and an electrically conductive layer on a surface of the nonconductive layer and generally parallel to a longitudinal direction of the inner end segment, wherein the nonconductive layer electrically isolates the electrically conductive layer from the respective lead upon which the nonconductive layer is positioned; wherein the inner end segment of each of a first subset of the leads extends further toward a center of the lead frame than the inner end segment of each of a second subset of the leads; and wherein a width of the inner end segment of the first subset of the leads is greater than a width of the inner end segments of the second subset of the leads.
