Ink jet printhead nozzle plates

A method for making an inkjet printhead nozzle plate from a composite strip containing a nozzle layer (10) and an adhesive layer (24) is disclosed. The adhesive layer (24) is coated with a polymeric sacrificial layer (28) prior to laser ablating the flow features (16,18,20) in the composite strip. A...

Zusammenfassung:	A method for making an inkjet printhead nozzle plate from a composite strip containing a nozzle layer (10) and an adhesive layer (24) is disclosed. The adhesive layer (24) is coated with a polymeric sacrificial layer (28) prior to laser ablating the flow features (16,18,20) in the composite strip. A method is also provided form improving adhesion between the adhesive layer (24) and the sacrificial layer (28). Once the composite strip containing the sacrificial layer (28) is prepared, the coated composite strip is then laser abated to form flow features (16,18,20) in the strip in order to form the nozzle plates. After forming the flow features, the sacrificial layer (28) is removed. Individual inkjet printhead nozzle plates are separated from the composite strip by singulating the nozzle plates with a laser.
