Title:
METHOD AND DEVICE FOR MANUFACTURE OF INK JET HEAD
Document Type and Number:
Japanese Patent JP3127748
Kind Code:
B2
Abstract:

PURPOSE: To reduce the manufacturing cost of an ink jet head.
CONSTITUTION: An electrode film up to a side wall section 2a of a flow path channel 2 of a flow path base 1 is formed by an electrode film forming device provided with a deposition position 15 for forming the electrode film, a table positioned away from the source by the given distance and a plurality of mounting jigs to be so retained as to make the relative position of the flow path base to the deposition source all constant. The incidence of a deposition metal to respective mounting jigs is performed from the opposite side of a nozzle plate bonding section 1a in the range of δ=90-180° to a flow path channel forming surface 1b, and the flow path base 1 is retained in the state of inclining to the deposition source 15 by the angle θ relatively so that the incidence of the deposition metal is performed from the end of the side wall section through the flow path channel by a given distance. When the flow path base is mounted on the mounting jig and the incidence of the deposition metal is emitted from the deposition source 15, a thin metal film forming the electrode film is formed on the wall section, and as the thin metal film is not formed on the nozzle plate boring section, a troublesome grinding process forming the cause of damage of the side wall section can be eliminated.
