Abstract:
An automated method of fabricating electronic packaging units comprising the steps of providing a first substantially planar lead frame defining a first aperture and at least one first lead extending into the aperture; providing a second heat sink lead frame segment defining a second aperture and including at least one second lead extending into said second lead frame aperture, wherein the second lead is provided with at least one hole extending therethrough; overlaying the first lead frame segment and the second heat sink lead frame segment and positioning the first and second leads apart from each other by a distance defining a space; and riveting the first and second lead frame segments together with a deposit of flowable molding material into the space defined by the predetermined distance between the first lead and the second heat sink lead, the molding material flowing though the at least one hole in the second heat sink lead frame portion, thereby forming said molded body, wherein the molded body is structured to expose contact surfaces for each of the first lead and second lead.
