ABSTRACT:
A leadframe of a conductive material includes a central region to accommodate a chip and a plurality of connecting fingers extending at least from one side in the direction of the central region, a contact region being provided adjacent to the central region on at least some of the connecting fingers. The course of the connecting fingers is such that a sectional face in an arbitrary imaginary cross-section at right angles to the main face of the leadframe has leadframe material. In such a case, it is attempted to keep cross-sections in a component without leadframe material as small as possible.
