  • Patent number: 8344270
    Abstract: A combination of a main carrier and a printed circuit board. Light and heavy electrical and/or electronic components are fixed on the printed circuit board, wherein at least one heavy component is mechanically fixedly connected to the main carrier and electrically conductively connected to conductor tracks of a first section of the printed circuit board. The first section of the printed circuit board is electrically conductively connected to a second section of the printed circuit board and decoupled from the second section of the printed circuit board with regard to mechanical vibrations by means of a decoupling device. The decoupling device may be, for example, a flexible section or a recess formed in said printed circuit board.

  • Patent number: 8338942
    Abstract: A power semiconductor module, for placement on a cooling component. The module includes a substrate, at least two power semiconductor components arranged on the substrate, a housing and outwardly routed load and control connections. The substrate has an insulator body with a first main area that faces the interior of the power semiconductor module, and has interconnects at load potential arranged thereon. Each load connection is formed as a shaped metal body with outer contacts, a strip-like section and with inner contacts extending from the strip-like section to the substrate and making circuit-compliant contact therewith. In addition, the load connections are substantially completely encased by insulation except in the vicinity of the outer and inner contacts and accordingly are electrically insulated from one another.

  • Patent number: 8324717
    Abstract: A power semiconductor module comprising a substrate, a circuit formed thereon and having a plurality of conductor tracks that are electrically insulated from one another and power semiconductor components arranged on the conductor tracks. The latter are connected in a circuit-conforming manner by a connection device, which has an alternating layer sequence of at least two electrically conductive layers with at least one electrically insulating layer between them. In this case, the substrate has a first sealing area, which uninterruptedly encloses the circuit. Furthermore, this sealing area is connected to an assigned second sealing area on a layer of the connection device by a connection layer. According to the invention, this power semiconductor module is produced by applying pressure to the substrate, to the power semiconductor components and to the connection device.

  • Patent number: 8283784
    Abstract: A method for making a power semiconductor module and a module produced by that method, wherein the module includes a substrate, a connection device and load terminal elements, wherein power semiconductor components are arranged on a conductor track of the substrate and connected to one of the load terminal element by the connection device. The power semiconductor module has auxiliary contact pads which can be connected to an external printed circuit board. The primary production step in this case is cohesively connecting respective first contact areas of the first conductor tracks to at least one second contact area of a power semiconductor component and at least one third contact area of a load terminal element; afterwards, the assemblage composed of at least one power semiconductor component of a connection device and load terminal elements is arranged to form a housing of the power semiconductor module.

  • Patent number: 8264071
    Abstract: A power semiconductor module having at least one fuse. The power semiconductor module comprises a housing, load terminal elements that lead outside of the housing, and a substrate disposed inside the housing with a plurality of metal connecting tracks of different polarity electrically insulated from one another. On at least one of these connecting tracks, at least one power semiconductor component is disposed and is connected correctly in terms of circuitry to first connecting elements that have a first line cross section. The fuse comprises a second connecting element that has a second line cross section, less than the first, and is disposed between two connecting tracks and/or between a connecting track and a load terminal element. The second connecting element is sheathed in one portion by an explosion protection means.
