Porous Enclosure Patents (Class 204/297.11)
  • Patent number: 7828945
    Abstract: The present invention can provide 1 which barrel plating apparatus where a plating barrel has permeable holes and slits in a size of order of micrometers on the wall thereof. The plating barrel is fabricated with porous plastic materials which have permeable holes and slits to the plating liquid and no piece materials to be plated are dropped thereof. Further advantage of the present invention is to provide a drain tool to drain the plating liquid L staying in the plating barrel.

  • Patent number: 6673218
    Abstract: A cathode cartridge (N) for an electroplating tester includes a cathode conductor (10) that conducts electricity to a surface (Wa) to be plated of a silicon wafer (W) as an object to be plated, a first insulator (20) that covers a front side of the silicon wafer (W) and holds the cathode conductor (10), and a second insulator (30) that covers a back side of the silicon wafer (W) and holds the silicon wafer (W). Negative portions other than the surface (Wa) to be plated of the silicon wafer (W) are insulated from plating solution with a first O-ring (22) fitted in the first insulator (20) and a second O-ring (32) fitted in the second insulator (30).

  • Publication number: 20030102212
    Abstract: In a cable system for connecting to an electrical apparatus, an earthing electrode assembly includes an earthing electrode, a mechanism for attaching the electrode to the cable while maintaining electrical insulation from the cable, and an electrical connection of the electrode to the electrical apparatus, the connection being long enough that the electrode is located at a distance from the apparatus such that the apparatus is substantially protected from the electrochemical effects resulting from operation of the electrode. The earthing electrode may include a titanium core which is coated with platinum or a mixed metal oxide of tantalum and iridium. Methods of attachment are also disclosed.

  • Patent number: 6569299
    Abstract: An anode includes an anode cup, a membrane and ion source material, the anode cup and membrane forming an enclosure in which the ion source material is located. The anode cup includes a base section having a central aperture and the membrane also has a central aperture. A jet is passed through the central apertures of the base section of the anode cup and through the membrane allowing plating solution to be directed at the center of a wafer being electroplated.
