INKJET PRINTHEADS CONTAINING EPOXY ADHESIVES AND METHODS FOR FABRICATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide adhesives to fix plates within a printhead stack that are stable upon exposure to UV inks.SOLUTION: An inkjet printhead comprise a first plate, a second plate, and a cured adhesive composition disposed between and bonding the first plate and the second plate. The cured adhesive composition has a glass transition temperature greater than about 115°C and is stable when exposed to acrylate monomer. Further, the inkjet printhead comprises a first plate, a second plate, and a cured thin film adhesive disposed between and bonding to both of the first plate and the second plate. The cured thin film adhesive contains a polyimide film disposed between a cured first adhesive layer and a cured second adhesive layer.
