Method for manufacturing leadframe, packaging method for using the leadframe and semiconductor package product
Abstract:
A leadframe package includes a die pad with four unitary, outwardly extending slender bars; a plurality of leads arranged along periphery of the die pad; a separate pad segment separated from the die pad and isolated from the plurality of leads; a semiconductor die mounted on an upper side of the die pad, wherein the semiconductor die contains first bond pads wire-bonded to respective the plurality of leads and a second bond pad wire-bonded to the separate pad segment; and a molding compound encapsulating the semiconductor die, the upper side of the die pad, the first suspended pad segment and inner portions of the plurality of leads.
