3. A method for the production of a lead frame, comprising:
forming first partial insert-moldings on first partial regions of a core element, the core element including a plurality of elongate conductor tracks arranged next to one another;
forming second partial insert-moldings on second partial regions of the core element,
wherein the first partial insert-moldings and the second partial insert-moldings together form a complete insert-molding that completely encases the core element,
wherein adjacent first partial regions are spaced apart from one another, and each of the first partial insert-moldings surrounds only one individual conductor track, and
wherein the first partial insert-moldings are formed on the first partial regions of the core element by local insert molding of a plurality of adjacent conductor tracks and subsequent interruption of a retaining insert-molding formed in such a manner in regions between adjacent conductor tracks.
