Method of producing printer head using piezoelectric member

摘要

Disclosed herein is a method of producing a printer head. A substrate including at least one piezoelectric member polarized in its thickness direction is formed. A plurality of grooves and a plurality of posts are alternately defined in the substrate. A pre-processing solution is allowed to flow along the grooves at the following relative velocity so as to effect pre-processing when the velocity of the pre-processing solution for electroless plating relative to an object to be plated is V, the height of each of electrodes formed on the internal surfaces of the grooves is H, the width of each groove is W and a contact angle at which the pre-processing solution is brought into contact with the internal surfaces of the grooves is theta . $Thereafter,\; the\; substrate\; is\; immersed\; in\; an\; electroless\; plating\; solution\; to\; form\; the\; electrodes.\; A\; roof\; is\; joined\; to\; the\; surface\; of\; the\; substrate\; so\; as\; to\; close\; the\; top\; opening\; surfaces\; of\; the\; grooves,\; thereby\; defining\; a\; plurality\; of\; pressure\; chambers.\mathop{\mathrm{image}}$
