A printhead assembly includes a carrier including a substrate and a substructure joined to a first surface of the substrate, and a plurality of printhead dies each mounted on a second surface of the substrate. The first surface of the substrate includes a surface deformation and the substructure is joined to the first surface by an adhesive. As such, the adhesive conforms to the surface deformation.

A carrier for a plurality of fluid ejection devices includes a substrate and a substructure. The substrate includes a first material and has a first side adapted to receive the fluid ejection devices and a second side opposite the first side, and the substructure is formed of a second material and joined to the second side of the substrate with a lap joint. The lap joint includes a first portion formed by a portion of one of the substrate and the substructure, a second portion formed by a portion of the other of the substrate and the substructure, and a third material interposed between the first portion and the second portion.

An inkjet printhead assembly includes a carrier and a plurality of printhead dies. The carrier includes a substrate and an electrical circuit. The substrate has a first side and a second side such that the electrical circuit is disposed on the second side of the substrate. The printhead dies are each mounted on the first side of the substrate and electrically coupled to the electrical circuit Thus, the substrate provides support for the printhead dies while the substrate and the electrical circuit together accommodate fluidic and electrical routing to the printhead dies.

An inkjet printing system includes a mounting assembly and an inkjet printhead assembly. The mounting assembly includes a plurality of datums and the inkjet printhead assembly includes a carrier and a plurality of printhead dies each mounted on the carrier. The inkjet printhead assembly is mounted in the mounting assembly such that the carrier contacts at least one of the datums. Thus, positioning of the carrier relative to the mounting assembly is established.

A wide-array inkjet printhead assembly includes a carrier having a first side and a second side contiguous with the first side, and a plurality of printhead dies each mounted on the first side of the carrier. An electrical circuit is disposed on the first side and the second side of the carrier. As such, a plurality of electrical connectors are each electrically coupled to the electrical circuit and one of the printhead dies.

An inkjet printhead assembly includes a substrate having a non-planar surface and a plurality of adhesive quantities each disposed on the non-planar surface of the substrate. As such, a plurality of printhead dies are each adhered to the non-planar surface of the substrate by one of the adhesive quantities. A thickness of at least one of the adhesive quantities varies from the thickness of another of the adhesive quantities such that the thickness of the adhesive quantities compensates for the non-planar surface of the substrate. Thus, the adhesive quantities support the printhead dies and establish a substantially coplanar relationship among the printhead dies.
