  • Patent number: 8557099
    Abstract: An electrically conductive protective coating or film is provided over the surface of a reflective coating of a solar mirror by flowing or directing a cation containing liquid and an anion containing liquid onto the conductive surface. The cation and the anion containing liquids are spaced from, and preferably out of contact with one another on the surface of the reflective coating as an electric current is moved through the anion containing liquid, the conductive surface between the liquids and the cation containing liquid to coat the conductive surface with the electrically conductive coating.

  • Patent number: 8551313
    Abstract: An electroplating apparatus and method for depositing a metallic layer on the surface of a wafer is provided wherein said apparatus and method do not require physical attachment of an electrode to the wafer. The surface of the wafer to be plated is positioned to face the anode and a plating fluid is provided between the wafer and the electrodes to create localized metallic plating. The wafer may be positioned to physically separate and lie between the anode and cathode so that one side of the wafer facing the anode contains a catholyte solution and the other side of the wafer facing the cathode contains an anolyte solution. Alternatively, the anode and cathode may exist on the same side of the wafer in the same plating fluid. In one example, the anode and cathode are separated by a semi permeable membrane.

  • Publication number: 20130240366
    Abstract: Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on top and bottom sides of a monolithic structure can facilitate the formation of wrap-around plated terminations.

  • Publication number: 20130233719
    Abstract: Methods and systems for masking interior surfaces of a part from exposure to a subsequent process. In some embodiments the interior surfaces are threaded. Methods include forming a plugged insert by overmolding a masking plug material into an opening in the insert, the plug being substantially impervious to exposure to a subsequent process. The plugged insert can then be assembled in the part and the part is exposed to the process. Processes can include anodizing, cleaning, machining and laser etch processes. After the process is complete, the plug is removed from the insert, leaving the insert in the part without the plug. The described embodiments describe methods for optimizing masking methods in a production setting. More specifically, embodiments describe methods for automatic insertion and removal of plugs in a part before and after exposure of the part to a process such as anodization.

  • Patent number: 8523966
    Abstract: The surface of cutters for dentistry is rendered passive to electroplating by immersion in a concentrated aqueous solution of nitric acid for a certain period of time. This is followed by painting a length including the surface marked out by the slots, the surface inside the slots and the surface at the tip, using an electrically insulating paint resistant to acids. Each cutter is then ground using a grinding wheel with rotating disk having an abrasive edge shaped like the continuous profile of the painted surface. Grinding removes the paint together with a micrometric layer of metal from the surface except for that inside the slots. The shank is ground and painted for a length adjacent to the slots.

  • Patent number: 8512578
    Abstract: Multi-layer structures are electrochemically fabricated from at least one structural material (e.g. nickel), that is configured to define a desired structure and which may be attached to a substrate, and from at least one sacrificial material (e.g. copper) that surrounds the desired structure. After structure formation, the sacrificial material is removed by a multi-stage etching operation. In some embodiments sacrificial material to be removed may be located within passages or the like on a substrate or within an add-on component. The multi-stage etching operations may be separated by intermediate post processing activities, they may be separated by cleaning operations, or barrier material removal operations, or the like. Barriers may be fixed in position by contact with structural material or with a substrate or they may be solely fixed in position by sacrificial material and are thus free to be removed after all retaining sacrificial material is etched.

    Abstract: A method of forming a nano-structure (100?) involves forming a multi-layered structure (10) including an oxidizable material layer (14) established on a substrate (12), and another oxidizable material layer (16) established on the oxidizable material layer (14). The oxidizable material layer (14) is an oxidizable material having an expansion coefficient, during oxidation, that is more than 1. Anodizing the other oxidizable material layer (16) forms a porous anodic structure (16?), and anodizing the oxidizable material layer (14) forms a dense oxidized layer (14?) and nano-pillars (20) which grow through the porous anodic structure (16?) into pores (18) thereof. The porous structure (16?) is selectively removed to expose the nano-pillars (20). A surface (I) between the dense oxidized layer (14?) and a remaining portion of the oxidizable material layer (14) is anodized to consume a substantially cone-shaped portion (32) of the nano-pillars (20) to form cylindrical nano-pillars (20?).
