An inkjet printhead assembly comprising an ink supply manifold: printhead integrated circuits and a connector film for supplying power to drive circuits in the printhead integrated circuits. Each prithead integrated circuit has a frontside comprising the drive e circuitry and inkjet nozzle assemblies, a backside attached to the ink supply manifold, and ink supply channels providing fluid communication between the backside and the inkjet nozzle assemblies. A connection end of the connector film is sandwiched between part of the ink supply manifold and the printhead integrated circuits.
