Patent ID: 7862678

Claim:
A method of forming a plurality of electromechanical devices comprising: applying an adhesive in a liquid state and not appreciably cured to stainless steel substrate previously attached to a fluid channel substrate at a temperature that is below a cure temperature of the adhesive, wherein the adhesive comprises a liquid at a temperature below the cure temperature of the adhesive; positioning a laminar piezoelectric structure on the adhesive while the adhesive is not appreciably cured, wherein the piezoelectric structure positioned against the stainless steel substrate forms an assembly; heating the assembly at a temperature below the cure temperature of the adhesive while compressing the assembly to squeeze the adhesive into an adhesive layer such that the laminar piezoelectric structure is attached to the stainless steel substrate by an adhesive layer that is not appreciably cured; after heating and compressing the assembly, cooling the assembly to room temperature; individually laser cutting the pre-cured laminar piezoelectric structure being held against the stainless steel substrate by the adhesive layer, the cutting made in alignment with pressure chambers in the fluid channel substrate while the adhesive layer is not appreciably cured to form a plurality of electrically isolated piezoelectric devices; and, curing the adhesive layer of the assembly after laser cutting the laminar piezoelectric structure.
