Abstract:
Methods and resulting devices are disclosed related to attaching a die to a leadframe. One such method includes initially bonding a carrier pad which is pre-coated with a thermosetting first adhesive to the leadframe. The carrier pad can be electrically non-conductive. The first adhesive can be raised to its thermosetting cure temperature by heating the leadframe to a temperature just above the thermosetting cure temperature of the first adhesive. A thermosetting second adhesive which is liquid at room temperature can be applied to a second major surface of the carrier pad, and the die can be placed on the second adhesive and aligned with the leadframe. The second adhesive can be raised to its thermosetting cure temperature to bond the die to the carrier pad, and in turn form a bonded assembly.
