摘要:
Methods and systems of protecting substrates that are intended for use in fluidic devices are described. In accordance with one embodiment, sealant material is applied over one or more edges of at least one multi-chip module substrate that is intended for use in a fluidic device. At least one edge has an exposed electrical interconnect and the sealant material is applied over less than an entirety of the substrate and sufficiently to cover the exposed electrical interconnect. The sealant material is exposed to conditions effective to seal the one or more edges.

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 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.
