Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of forming an inkjet printhead, said method comprising 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 one or more ink supply channels, such that each shim aperture is in fluid communication with a respective ink supply channel; and bonding one or more printhead chips to the shim, thereby forming the inkjet printhead. 2. The method of claim 1 , wherein the shim is comprised of a metal alloy having a coefficient of thermal expansion (CTE) of 5 ppm/° C. or less. 3. The method of claim 1 , wherein the shim is comprised of an alloy of iron and at least one other metal selected from the group consisting of: nickel, cobalt and chromium. 4. The method of claim 1 , wherein the shim is comprised of Invar 36. 5. The method of claim 1 , wherein the manifold is a one-piece structure. 6. The method of claim 1 , wherein the manifold is comprised of a same metal alloy as the shim. 7. The method of claim 6 comprising the further step of nitriding the manifold. 8. The method of claim 1 , wherein the shim has a thickness in the range of 100 to 1000 microns.
