Abstract
A processing method of electroless plating in which a catalyst layer is absorbed on a surface of a substrate, a laser beam is selectively applied to the catalyst layer, processing of electroless plating is applied to the substrate, thereby a plating layer is not formed on a part to which the laser beam has been applied, and a plating layer is formed on a part to which laser beam has not been applied.
Claims9
A method for producing an ink-jet print head in which ink is jetted from an ink channel by applying an electric voltage to an electrode and a wiring thereof for use in driving a piezoelectric body, the method comprising the steps of:
- (a) forming the ink channel by a member including the piezoelectric body;
- (b) absorbing an activated catalyst layer on an entire surface of the piezoelectric body;
- (c) selectively radiating a laser beam to the catalyst layer to remove a selectively radiated portion of the catalyst layer;
- and
- (d) electroless-plating on the piezoelectric body, thereby not forming the electrode and the wiring on a portion of the piezoelectric body to which the laser beam has selectively radiated, and forming the electrode and the wiring on a portion to which the laser beam has not radiated.
A method for producing an ink-jet print head in which ink is jetted from an ink channel by applying an electric voltage to an electrode and a wiring thereof for use in driving a piezoelectric body, the method comprising the steps of:
- (a) forming the ink channel by a member including the piezoelectric body;
- (b) absorbing an activated catalyst layer on an entire surface of the piezoelectric body;
- (c) selectively making a photochemical reaction to occur in the catalyst layer to inactivate a selectively photochemical reacted portion of the catalyst layer;
- and
- (d) electroless-plating on the piezoelectric body, thereby not forming the electrode and the wiring on a portion of the piezoelectric body where the photochemical reaction has selectively occurred, and forming the electrode and the lead wiring on a portion where the photochemical reaction has not occurred.
