Method for facilitating assembly of a printhead having a polymer layer

A method for assembling an inkjet jet print head enables piezoelectric transducers to be bonded to an inkjet ejector without closing inlets to a pressure chamber within the inkjet ejector. The method includes bonding a polymer layer to a diaphragm layer having a plurality of openings, bonding piezoe...

Zusammenfassung:	A method for assembling an inkjet jet print head enables piezoelectric transducers to be bonded to an inkjet ejector without closing inlets to a pressure chamber within the inkjet ejector. The method includes bonding a polymer layer to a diaphragm layer having a plurality of openings, bonding piezoelectric transducers to the diaphragm layer with a thermoset adhesive, placing thermoset polymer in areas between the piezoelectric transducers on the diaphragm layer, and drilling inlets through the thermoset polymer and the diaphragm at the openings in the diaphragm.
