Abstract:
1. A method for making an inkjet head, comprising: forming a groove on a channel plate comprising a piezoelectric material; adhering a cover plate, on the channel plate having the groove, to form an ink chamber; cutting the channel plate to form plural head chips, each head chip of the plural head chips having the ink chamber; forming a metallic layer on a surface of the each head chip including a surface of the ink chamber; irradiating a laser beam on the metallic layer to remove a part of the metallic layer, to form an independent electrode pattern for each of the ink chamber; adhering a nozzle plate on a first plane of the each head chip, the first plane contacting one end of the ink chamber; adhering a print circuit, connected to a drive control substrate, on a second plane of the head chips such that the print circuit contacts the electrode pattern formed on the each head chip; wherein the laser beam is emitted from a solid laser and has a wavelength of not longer than 355 nm.
