Abstract: An inkjet printhead includes: a rigid elongate manifold having ink supply channels extending along its length and a plurality of ink outlets defined therein; a shim attached to the manifold, the shim having a plurality of shim apertures for receiving ink from the ink outlets; and a plurality of printhead chips adhesively bonded directly to the shim, each printhead chip receiving ink from one or more of the ink outlets. The shim is formed of a metal alloy having a CTE of 5 ppm/° C. or less and includes an adhesion-promoting surface film layer.

Abstract: A method of forming an inkjet printhead. The method includes the steps of: providing a metal alloy shim having a plurality of shim apertures; nitriding a surface of the shim; bonding the shim to a rigid elongate manifold having ink supply channels, such that each shim aperture is in fluid communication with a respective ink supply channel; and bonding printhead chips to the shim, thereby forming the inkjet printhead.
