    摘要: A device (100) and method (200) for bonding a ribbon wire (104) to a workpiece (106) comprising feeding the ribbon wire through a passageway (116) of an ultrasonic bond capillary (102) and clamping the ribbon wire against an engagement surface (120) of the bond capillary via a clamping jaw (118) operably coupled to the bond capillary. The ribbon wire (104) is bonded to the workpiece (106) along a bonding surface (112) of the bond capillary (102) and penetrated, at least partially, between the bonding surface and the engagement surface (120) of the bond capillary by a cutting tool (124). The cutting tool (124) may comprise an elongate member (126) positioned between the bonding surface (112) and engagement surface (120), and may have a cutting blade (128) positioned at a distal end (130) thereof. The cutting tool (124) may further comprise a ring cutter (132), wherein the ribbon wire passes through a ring (134) having a cutting surface (138) defined about an inner diameter thereof.

    摘要: A semiconductor device comprising a leadframe (903), which has first (903a) and second (903b) surfaces, a planar pad (910) of a certain size, and a plurality of non-coplanar members (913) adjoining the pad. The device further has a heat spreader (920) with first (920a) and second (920b) surfaces, a planar pad of a size matching the leadframe pad size, and contours (922), into which the leadframe members are inserted so that the first spreader pad surface touches the second leadframe pad surface across the pad size. A semiconductor chip (904) is mounted on the first leadframe pad surface. Encapsulation material (930), preferably molding compound, covers the chip, but leaves the second spreader surface uncovered.
