Abstract:
1. A leadless lead frame electronic package (LLP), comprising: a lead frame of thermally and electrically conductive material encapsulated in an encapsulation of electrically-insulating material to define a planar mounting surface; wherein the lead frame includes an internal planar surface defined by the conductive material and the encapsulating insulating material and an external planar surface also defined by the conductive material and the encapsulating insulating material, the internal planar surface and the external planar surface being parallel to each other, wherein a portion of the lead frame defines a die attach pad, the die attach pad having an internal surface and external surface; wherein the die attach pad internal planar surface is coplanar with the internal planar surface of the lead frame and the die attach pad external surface is coplanar with external planar surface of the lead frame; wherein other portions of the lead frame define a plurality of connection pads electrically isolated from the die attached pad, each connection pad has an internal surface and an external surface; wherein connection pad internal surface is coplanar with internal planar surface of the lead frame and an external surface coplanar with external planar surface of the lead frame; and wherein the external planar surface of the lead frame is coplanar with the planar mounting surface such that the leadless lead frame electronic package (LLP) provides for a coplanar contact areas for the die attach pad and the connection pads whereby need for metal leads extending from the lead frame is eliminated.
