Joining of different materials of carrier for fluid ejection devices

摘要

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.
