  • Patent number: 5465899
    Abstract: An wire bonding apparatus for forming ball and stitch bonds includes a bond head (42) having a shaved capillary (20), a carrier (43) for holding the bond head (42), a bearing (44) on which the carrier (43) is mounted, and a bearing table (46) on which the bearing (44) is mounted. The bearing table (46) and bearing (44) provide rotary movement about a z axis for the capillary (20). An x-y table (48) on which the carrier bearing table (46) is mounted provides movement in x and y directions for the capillary (20). A fixed work holder (50) supports a semiconductor die (11) and a leadframe (52) adjacent the capillary (20). The relative rotation provided between shaved capillary (20) and work holder (50) provides proper orientation of the capillary (20) with respect to leadframe (52) to form high quality stitch bonds on leadframe (52) while permitting fine pitch ball bonds to be formed on the semiconductor die (11).
