  • Publication number: 20210021179
    Abstract: A circuit arrangement is disclosed herein. The circuit arrangement includes a circuit carrier board, a power semiconductor arranged on the underside of the circuit carrier board, and a wiring carrier board arranged underneath the power semiconductor. The circuit arrangement further includes a metallic first spacer element arranged between the circuit carrier board and the wiring carrier board and via which an electric load current from the power semiconductor flows, wherein the first spacer element acts as a shunt through which current flows. The circuit arrangement further includes a voltage measuring unit, by which a voltage drop across the first spacer element, produced by the load current flow, may be determined. A converter having such a circuit arrangement, an aircraft having a converter, and a method for current measurement in power semiconductors are likewise specified.

  • Publication number: 20200152532
    Abstract: Various embodiments include an electronic assembly comprising: a first substrate; a second substrate; and a component located between the first substrate and the second substrate. The component is in contact with the first substrate and the second substrate. A gap between the first substrate and the component is bridged with an auxiliary joining material. The first substrate defines a through-hole opening into the gap and sealed by the auxiliary joining material. The first substrate and the second substrate define a cavity closed against the environment.

  • Patent number: 9888559
    Abstract: A method for producing or disassembling an electronic assembly are provided. The assembly may have a heating device integrated into a substrate. The heating device can be heated via an external power supply during the assembly process so that, for example, solder connections of an electric component can be melted. The heating device can also be used when operating the electronic assembly, and the heating device can then be directly actuated by the component. For this purpose, an electric connection is then established between the component and the heating device, the connection not yet being provided during the thermal assembly process in order to protect the electronic components of the circuit from being damaged.
