PRINTHEAD INTEGRATED CIRCUIT HAVING COMMON CONDUCTIVE TRACK FUSED TO NOZZLE PLATE

摘要

An inkjet printhead integrated circuit (IC) includes: a substrate having a drive circuitry layer; a plurality of nozzle assemblies disposed on an upper surface of the substrate and arranged in one or more nozzle rows extending longitudinally along the printhead IC; a nozzle plate extending across the printhead IC; and a conductive track fused to the nozzle plate which extends longitudinally along the printhead IC and parallel with the nozzle rows. The conductive track is connected to a common reference plane in the drive circuitry layer via a plurality of conductor posts extending between the drive circuitry layer and the conductive track.
