Abstract
A local plating apparatus includes a fiber, a laser beam penetrating nozzle or a laser beam penetrating mask through which a laser beam can be directly irradiated on a portion to be plated when plating is conducted on the portion to be plated using a jet of plating solution. The apparatus enables a laser beam to reach the portion to be plated in a stable state, and ensures a high plating speed and uniform plating quality.
Claims5
An apparatus for locally plating a material, said apparatus comprising:
- a plurality of convergingly oriented nozzles for individually applying jets of plating solution to a site on said material to be plated such that the jets converge at the site;
- laser beam generation means for generating a laser beam;
- and
- an optical fiber for introducing the laser beam generated by said laser beam generation means to a vicinity of the site to be plated to directly irradiate the vicinity of the site with the laser beam, wherein the optical fiber is disposed exteriorly of said nozzles with a beam exit end thereof positioned proximate and perpendicular to the material such that the laser beam can irradiate said site independently of said nozzles.
An apparatus for locally plating a material, said apparatus comprising:
- laser beam generation means for generating a laser beam;
- and
- a laser beam penetrating nozzle for applying a jet of plating solution to a portion of said material on which plating is conducted and for transmitting the laser beam generated by said laser beam generation means by total reflection within a wall portion thereof to directly irradiate the portion to be plated with the laser beam.
An apparatus for locally plating a material, said apparatus comprising:
- a nozzle for applying a jet of plating solution to a portion of said material to be plated;
- laser beam generation means for generating a laser beam;
- and
- a laser beam penetrating mask for transmitting the laser beam generated by said laser beam generation means by total reflection within a wall portion thereof to directly irradiate the portion to be plated with the laser beam, said laser beam penetrating mask being disposed on a surface of the material to be plated such that it covers a portion of said material other than the portion to be plated.
An apparatus for locally plating a material, said apparatus comprising:
- a nozzle for applying a jet of plating solution to a portion of said material to be plated;
- laser beam generation means for generating a laser beam;
- and
- a mask disposed on a rear surface of the material to be plated and having an opening through which the laser beam generated by said laser beam generating means is transmitted by being reflected by an inner peripheral surface of said opening so as to irradiate the transmitted laser beam onto the rear surface of the portion to be plated.
