  • Patent number: 11955402
    Abstract: A power semiconductor component is specified, having a power semiconductor device arranged within a housing, wherein a heat sink is exposed on a first surface of the housing; a wiring substrate which receives the housing with the power semiconductor device and which has a first main surface and a second main surface. A heat dissipation region with increased thermal conductivity is arranged on the second main surface. The housing is arranged on the wiring substrate in such a way that the heat sink is connected to the heat dissipation region via a solder layer. A number of spacers which are arranged between the heat sink and the heat dissipation region are embedded in the solder layer. Furthermore, a method for producing a power semiconductor component is specified.

  • Publication number: 20240096738
    Abstract: A power semiconductor component includes at least one power semiconductor device disposed within a housing and a heat sink having an area a exposed on a first surface of the housing. A wiring substrate has a first main surface and a second main surface. A heat dissipation region with increased thermal conductivity is disposed on the second main surface. The heat dissipation region has an area A on the second main surface, and a<A. The housing with the power semiconductor device is disposed on the second main surface of the wiring substrate in such a way that the heat sink is disposed completely on the heat dissipation region and is connected thereto by way of a solder layer. A method for producing a power semiconductor component is also provided.

  • Patent number: 6244740
    Abstract: A mixer is used for producing multi-component pastes at a mixing ratio other than 1:1. A deviating channel 20 is provided between the inlet opening 16 for the component of the larger volume proportion and the mixing chamber, to delay the feed of this component with respect to the other component. The presence of this deviating channel 20 causes all components to enter the mixing chamber simultaneously, thereby obtaining a paste which has the desired mixing ratio from the start.
