ABSTRACT:
A leadframe includes a first longitudinal side band, a second longitudinal side band integrally connected to the first band by transverse sectioning bars spaced longitudinally of the leadframe, a plurality of first leads located closer to the first side band between the respective sectioning bars, and a plurality of second leads integrally connected to the second side band between the respective sectioning bars. The first leads are integrally connected to the respective sectioning bars only via twistably slenderized segments. Each first lead can be turned over toward a corresponding second lead by torsioning the twistable segments.
