Abstract:
A heat treatment method for actuators of an ink jet printer head comprising the steps of:preparing an actuator comprising an ink pump section made by integrally firing a spacer plate with a plurality of window portions formed therein, a closure plate stacked on one side of the spacer plate for covering the window portions, and a connection plate stacked on the other side of the spacer plate for covering the window portions, each formed respectively of ceramic green sheets, and a piezoelectric/electrostrictive operating section composed of electrodes and a piezoelectric/electrostrictive layer formed on the outer surface of the closure plate;thereafter pasting the actuator onto a holding adhesive film;stripping the holding adhesive film from the actuator; andsubsequently heat-treating the actuator to remove adhesive, originating from the holding adhesive film, remaining on the actuator after stripping.
