INKJET PRINTHEAD ASSEMBLY HAVING ELECTRICAL CONNECTIONS VIA CONNECTOR RODS EXTENDING THROUGH PRINTHEAD INTEGRATED CIRCUITS

摘要

An inkjet printhead assembly includes: an ink supply manifold; printhead integrated circuits attached to the ink supply manifold, each printhead integrated circuit having a frontside including drive circuitry and a plurality of inkjet nozzle assemblies disposed on the drive circuitry; and a connector film for supplying power to the drive circuitry. An integrated circuit contact positioned in a backside recessed portion of each printhead integrated circuit is connected to the connector film. The integrated circuit contact is electrically connected to the drive circuitry via a connector rod extending through the printhead integrated circuit.
