METHOD FOR MANUFACTURING INK JET PRINT HEAD

摘要

PROBLEM TO BE SOLVED: To provide an economical method for manufacturing an ink jet print head having a high nozzle density per array and comprising nozzles and chambers associated with respective nozzles wherein each member is provided with means for supplying ink from each chamber to a belonging nozzle and ejecting ink therefrom. SOLUTION: The method for manufacturing an ink jet print head comprises a step for machining a plate simultaneously in parallel at the time of making the through holes of all members, a step for specially machining a member forming a chamber, a step for coupling a discrete member with at least one module and heat treating it consecutively, a step for fixing a piezoelectric element and bonding it to an already fixed conductor, and a step for assembling a print head.
