  • Patent number: 10388464
    Abstract: A method for manufacturing an electrolyte capacitor including at least the following steps: placing a valve-metal anode slug with its lower side on a substrate with a non-conductive epoxy target area without solder mask, curing the non-conductive epoxy, depositing a first conductive layer on the first end-face of the valve-metal anode slug and curing the first conductive layer, forming a dielectric on the valve-metal material of the valve-metal anode slug by anodization, depositing and curing a first non-conductive layer to cover an exposed surface of the first conductive layer, depositing a MnO2 layer and an electrically conductive coating, depositing a second conductive layer on the second end-face of the valve-metal anode slug and curing the second conductive layer, overmolding, and singulating of each single capacitor and the assembled substrate.

  • Publication number: 20160084771
    Abstract: The present invention refers to a sensor unit (10, 10?) for an electronic module (1) which is small and lightweight comprising at least one exposed component (5, 5 a, 5b) containing a chemical element and/or a chemical compound at its surface which is adapted to undergo a color change observed in visible light due to presence of a corrosive, the exposed component preferably containing elementary copper. The invention further refers to a respective electronic module (1) and a procedure to calculate the level of corrosive exposure of such an electronic module (1).

  • Patent number: 8801809
    Abstract: An aluminum slug anode usable in capacitors is produced from multiple-stacked layers of aluminum foils. The foils are stacked (possibly after cutting them to have an area similar to the area desired for the anode), hot-pressed, sintered, and anodized to generate the anode. A contact in electrical communication with the foils is formed, as by welding a contact across at least some of the foils. A capacitor casing be formed by situating the anode within a casing which serves as a cathode, with the anode being wrapped in a dielectric such as separator paper.

  • Patent number: 8659912
    Abstract: A shielding device for shielding an electronic component (102) to be mounted on a printed circuit board (132). The shielding device exhibiting a top shielding (110) and a bottom shielding (120; 140; 160; 180) separable from each other, wherein the top shielding includes an electrically and/or magnetically conductive material and the bottom shielding is multilayered. The bottom shielding exhibits at least one electrically and/or magnetically conductive metal sheet layer (122; 162; 164) embedded between at least two insulating layers (126; 124) and includes at least two electrically conductive transmission lines (172; 174; 176) for conducting electric current to the electronic component. The top shielding and the conductive metal sheet layer are electrically isolated from the electronic component. The bottom shielding integrated into the printed circuit board and the top shielding and the bottom shielding designed such when they are attached to each other, they completely envelope the electronic component.
