Abstract:
An inkjet printhead assembly, comprising:a carrier having a first face and a second face and including a plurality of conductive layers, a plurality of conductive vias, and a plurality of insulative layers, the plurality of conductive layers including: a first interface layer disposed on the first face of the carrier, a second interface layer disposed on the second face of the carrier, and at least one power layer, at least one data layer, and at least one ground layer each interposed between the first interface layer and the second interface layer, each conductive via providing a conductive path through at least one of the insulative layers to provide electrical coupling between selected ones of the conductive layers; and a plurality of printhead dies each mounted on the first face of the carrier, each of the printhead dies electrically coupled to the first interface layer.
