  • Patent number: 10112234
    Abstract: A self-aligning swaging punch is provided for adjoining together a pin and a workpiece having a pinhole. The swaging punch comprises a shaft and a tip having an open-ended cavity. The shaft transfers an axial force from a press or hammer to the tip. The tip transfers the axial force from the shaft to a top surface of the workpiece near the pinhole. The tip may be spherical in shape for evenly deforming the workpiece near the upper edge of the pinhole. The open-ended cavity receives the pin therein and allows the pin to extend at least partially into the open-ended cavity while the tip contacts the workpiece. The open-ended cavity also ensures that the swaging punch is aligned with the pinhole and perpendicular to the surface of the workpiece when the pin is inserted into the pinhole such that the workpiece evenly deforms and presses against the pin.

The first and second depositions may be of the blanket or selective type. The repetition of the formation process for forming successive layers may be repeated with or without variations (e.g. variations in: patterns; numbers or existence of or parameters associated with depositions, etchings, and or planarization operations; the order of operations, or the materials deposited). Other embodiments form multi-layer structures using operations that interlace material deposited in association with some layers with material deposited in association with other layers.

    Abstract: Focused Electric Field Imprinting (FEFI) provides a focused electric field to guide an unplating operation and/or a plating operation to form very fine-pitched metal patterns on a substrate. The process is a variation of the electrochemical unplating process, wherein the process is modified for imprinting range of patterns of around 2000 microns to 20 microns or less in width, and from about 0.1 microns or less to 10 microns or more in depth. Some embodiments curve a proton-exchange membrane whose shape is varied using suction on a backing fluid through a support mask. Other embodiments use a curved electrode. Mask-membrane interaction parameters and process settings vary the feature size, which can generate sub-100-nm features. The feature-generation process is parallelized, and a stepped sequence of such FEFI operations, can generate sub-100-nm lines with sub-100-nm spacing. The described FEFI process is implemented on copper substrate, and also works well on other conductors.

  • Patent number: 7815784
    Abstract: An electro-composite tribological coating for coating a flexible or compliant structure, for example a structural seal, includes a cobalt and cobalt alloy base containing a fine dispersion of tribologically suitable particles such as chromium carbide (Cr3C2), silicon carbide (SiC), carbon graphite, and the like, which can be deposited directly on the outer surface of the seal as a near-net shape coating requiring little or no mechanical polishing or grinding. The coating is deposited on the seal in one embodiment by an electrolytic bath. In this manner, a near-net shape coating of a desirable thickness, for example having a thickness of about 0.005? and a desirable surface finish can be achieved in the as-plated condition with little or no additional polishing or grinding after coating.

  • Publication number: 20100193364
    Abstract: In some embodiments, a workpiece-surface-influencing device preferentially contacts the top surface of the workpiece, to chemically modify the surface at desired field areas of the workpiece without affecting the surfaces of cavities or recesses in the field areas. The device includes a substance which is chemically reactive with material forming the workpiece surface. The substance can be in the form of a thin film or coating which contacts the surface of the workpiece to chemically modify that surface. The workpiece-surface-influencing device can be in the form of a solid state applicator such as a roller or a semi-permeable membrane. In some other embodiments, the cavities are filled with material that prevents surface modification of the cavity surfaces while allowing modification of the field areas, or which encourages surface modification of the cavity surfaces while preventing modification of the field areas. The modified surface facilitates selective deposition of materials on the workpiece.

  • Publication number: 20100147795
    Abstract: A method for the selective surface treatment of a first workpiece on at least one of the metalized areas of the upper and/or underside, the first workpiece being releasably jointed to at least one additional workpiece on one of its faces so as to be sealed from the exterior in at least one partial area and the selective surface treatment of the areas not covered by the joined section being carried out in a treatment phase. Cooling and distribution of the metalized areas is made easier because the first workpiece is not flat and has on at east one face identically or different metalized areas or cavities across a whole or part of a surface. It also has at least one additional metallic protective layer or an additional metallic coating applied during the selective surface treatment.

  • Publication number: 20100032302
    Abstract: A microscopic metallic structure is produced by creating or exposing a patterned region of increased conductivity and then forming a conductor on the region using electrodeposition. In some embodiments, a microscopic metallic structure is formed on a substrate, and then the substrate is etched to remove the structure from the substrate. In some embodiments, a focused beam of gallium ion without a deposition precursor gas scans a pattern on a silicon substrate, to produce a conductive pattern on which a copper structure is then formed by electrochemical deposition of one or more metals. The structure can be freed from the substrate by etching, or can used in place. A beam can be used to access an active layer of a transistor, and then a conductor can be electrodeposited to provide a lead for sensing or modifying the transistor operation while it is functioning.

  • Patent number: 7655126
    Abstract: A method for making a gasket (32) for an internal combustion engine (20) includes forming a generally annual stopper (38) on a metallic gasket body (40) through the process of electrochemical deposition. An electrolytic cell is completed with the gasket body (40) forming a cathode. The stopper (38) is formed with a contoured compression surface (42) by selectively varying the electrical energy delivered to selected electrodes (70) over time. Electrolyte (48) rich with metallic ions is pumped at high speed through the inter-electrode gap. A PC controller (82) switches selected electrodes (70) ON at certain times, for certain durations, which cause metallic ions in the electrolyte (48) to reduce or deposit onto the gasket body (40), which are built in columns or layers into a three-dimensional formation approximating the target surface profile (106) for the compression surface (42). The subject method for building a three-dimensional formation can be applied to work parts other than cylinder head gaskets (32).

  • Patent number: 7628902
    Abstract: A method of electrochemical deposition uses microdroplets of electrolytic solution over a targeted small circuit element. Only the targeted circuit element is electrically biased so that deposition occurs on the surface of that element, underneath the microdroplet, and nowhere else unless it is under other microdroplet(s). The invented method achieves extremely accurate and selective electrochemical deposition with a tiny amount of electrolytic solution, compared to conventional submersive and/or immersive methods, and eliminates the need for masking or etching, reducing the costs of manufacture and amount of waste electrolytic solution produced.
