  • Patent number: 10672690
    Abstract: A method for manufacturing an electronic assembly features a semiconductor device with a first side and a second side opposite the first side to facilitate enhanced thermal dissipation. The first side has a first conductive pad. The second side has a primary metallic surface. By heating the assembly once, a first substrate (e.g. lead frame) is bonded to a first conductive pad via first metallic bonding layer; and second substrate (e.g., heat sinking circuit board) is bonded to a primary metallic surface via a second metallic bonding layer. In one configuration the second metallic bonding layer is composed of solder and copper, for example.
    Type: Grant
    Filed: September 24, 2019
    Date of Patent: June 2, 2020
    Assignee: DEERE & COMPANY

  • Patent number: 10356926
    Abstract: An electronic assembly comprises a gate drive module comprising multiple circuit board layers sandwiched together, where each layer has a central opening that is aligned with the other layers. A switching circuit chipset is positioned in the central opening. The switching circuit chipset has lead frames for providing electrical connections to the switching circuit chipset. The lead frames are alignable with pockets in two or more of the layers to facilitate alignment of the contact portions of the lead frames with corresponding conductive pads on the circuit board.

  • Patent number: 8545237
    Abstract: A connector comprises a generally cylindrical dielectric body with a central bore in the dielectric body. The dielectric body has a first end and second end opposite the first end. Conductors extend axially through the cylindrical dielectric body and are spaced apart from each other in a generally circular or elliptical arrangement. Each conductor comprises an embedded portion in the dielectric body and mating portions extending from the first end and the second end.
