Ulrich SAGEBAUM has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10665562
    Abstract: A power electronics method and assembly produced by the method. The assembly has a substrate, having a power semiconductor element, and an adhesion layer disposed therebetween, wherein the substrate has a first surface that faces a power semiconductor element, a power semiconductor element has a third surface that faces the substrate, the adhesion layer has a second surface which, preferably across the full area, contacts the third surface and has a first consistent surface contour having a first roughness, and wherein a fourth surface of the power semiconductor element that is opposite the third surface has a second surface contour having a second roughness, said second surface contour following the first surface contour.
    Type: Grant

  • Patent number: 10603741
    Abstract: A pressing ram having an elastic cushion element and intended for the material-bonded press-sintering connection of a first connection partner to a second connection partner of a power-electronics component. The elastic cushion element of the pressing ram is enclosed by a dimensionally stable frame, within which the cushion element and a guide part of the pressing ram are guided for linear movement such that the dimensionally stable frame lowers onto the first connection partner, or a workpiece carrier with the first connection partner arranged therein, and, following abutment against the same, the pressing ram together with the elastic cushion element is lowered onto the second connection partner and the elastic cushion exerts a pressure necessary for connecting the first connection partner to the second connection partner.
