  • Publication number: 20170207030
    Abstract: The present invention is directed to a method of etching anode foil in a non-uniform manner which minimizes thermal oxidation during foil cutting. Having less oxide improves the ability to cut through aluminum anodes with lower energy rates. In aluminum foils, it has been found that a masking step before etching reduces conversion of boehmite aluminum oxide to alpha-phase corundum during laser cutting of anodes, which increases edge quality and productivity. Additionally, the non-etched anode frame allows for less surface area to form during the aging process. As a result, the leakage current is reduced by the proportion of edge to anode surface area, and the aging process will be faster, leading to higher productivity.

  • Publication number: 20170200560
    Abstract: A capacitor and a method of processing an anode metal foil are presented. The method includes electrochemically etching the metal foil to form a plurality of tunnels. Next, the etched metal foil is disposed within a widening solution to widen the plurality of tunnels. Exposed surfaces of the etched metal foil are then oxidized. The method includes removing a section of the etched metal foil, where the section of the etched metal foil includes exposed metal along an edge. The section of the etched metal foil is placed into a bath comprising water to form a hydration layer over the exposed metal on the section of the etched metal foil. The method also includes assembling the section of the etched metal foil having the hydration layer as an anode within a capacitor.

  • Publication number: 20170191181
    Abstract: Anode foil, preferably aluminum anode foil, is etched using a process of treating the foil in an electrolyte bath composition comprising a sulfate, a halide, an oxidizing agent, and a surface active agent. The anode foil is etched in the electrolyte bath composition by passing a charge through the bath. The etched anode foil is suitable for use in an electrolytic capacitor.

  • Publication number: 20170110255
    Abstract: Device designs are presented that include a cathode subassembly for protecting the device from unwanted discharge, and aiding in alignment of the cathodes and anodes within a device. A device includes a conductive anode, a dielectric material disposed on a surface of the conductive anode, a conductive cathode, and an electrolyte disposed between the anode and the cathode. The conductive cathode is sandwiched between two separator sheets, the two separator sheets being adhered together at a peripheral edge in an area outside of a perimeter of the conductive cathode.

    Abstract: Methods and systems for registering a manipulator assembly and independently positionable surgical table are provided herein. In one aspect, methods include reading a fiducial marker on the surgical table with a sensor associated with the manipulator assembly and localizing the manipulator assembly and surgical table with respect to a common reference frame. Methods may further include translating a 3D configuration of the surgical table to a 2D frame of reference so as to estimate a 3D pose of the surgical table relative the manipulator assembly for use in coordinating movements therebetween.

  • Patent number: 9412525
    Abstract: Anode foils suitable for use in electrolytic capacitors, including those having multiple anode configurations, have improved strength, reduced brittleness, and increased capacitance compared to conventional anode foils for electrolytic capacitors. Exemplary methods of manufacturing an anode foil suitable for use in an electrolytic capacitor include disposing a resist material in a predetermined pattern on an exposed surface of an anode foil substrate such that a first portion of the exposed surface of the anode foil substrate is covered by the resist material, and a second portion of the exposed surface remains uncovered; polymerizing the resist material; exposing at least the second portion of the exposed surface to one or more etchants so as to form a plurality of tunnels; stripping the polymerized resist material; and widening at least a portion of the plurality of tunnels. The resist material may be deposited, for example, by ink-jet printing, stamping or screen printing.

  • Publication number: 20160141109
    Abstract: A method for patterning a metal substrate includes a series of surface treatments to control tunnel initiation at a micron or sub-micron level. In particular, the series of surface treatments include forming a hydration layer which acts as a mask while etching the surface of the metal substrate. The hydration layer mask enables control of the tunnel initiation on a micron or sub-micron level because the etching does not undercut the interface between the metal substrate and the hydration layer. As a result, the tunnels can be initiated in an orthogonal direction and closer together, thereby increasing the tunnel density.
