Method of fabricating printheads having multiple nozzle assemblies
First Claim
Patent Images
1. A method of fabricating printheads each having a plurality of nozzle assemblies positioned on a substrate from a plurality of sets of the nozzle assemblies positioned on the substrate, the method comprising the steps of:
- applying a guard defining a plurality of recesses to the substrate so that each set is located within a respective recess;
segmenting the substrate into discrete parts;
bonding an adhesive layer to a back side of the substrate, the adhesive layer being curable in the presence of ultraviolet light;
segmenting the guard into discrete parts corresponding to the discrete parts of the substrate thereby forming individual printheads; and
selectively exposing the adhesive layer to ultraviolet light allowing removal of individual printheads.
