Method of manufacture of an ink jet printer head

摘要

A manufacturing method for an ink jet printer head, includes the steps of cutting a plurality of channels for forming a plurality of ink chambers, on the upper surface of a substrate including at least one piezoelectric member polarized across its thickness; adsorbing Sn on the upper surface of the substrate including the inner surfaces of the channels; forming a pattern resist film on the upper surface of the substrate on which the Sn has been absorbed adsorbing Pd as a catalyst core for electroless plating on the electrode forming portions and the wiring pattern forming portions; separating the pattern resist film; immersing the substrate from which the pattern resist film has been separated into a plating liquid to deposit plating on the electrode forming portions and the wiring pattern forming portions; and mounting on the substrate a top plate for covering upper openings of the channels and a nozzle plate for covering front openings of the channels to form the above ink chambers.
