Abstract:
Disclosed is a method of manufacturing a lead frame, which comprises the steps of: providing an electrically-conductive base material having first and second planar sides; forming a plurality of conductive contact points on the first planar side of the base material; providing a non-conductive filling material over the first planar side of the base material so that the filling material fills spaces in-between the plurality of contact points to a form a layer comprising the filling material and the plurality of contact points; and etching the second planar side of the base material to expose a pattern of the filling material from the second planar side of the base material and to thereby form a plurality of isolated conductive regions on the second planar side of the base material, each isolated conductive region being connected with at least a respective one of the plurality of contact points on the first planar side of the base material. A lead frame structure is also disclosed.
