Definitions
- the invention relates to a power semiconductor module with a circuit arrangement on a substrate of a Base plate, at least one provided on the substrate Acceptance device for electric current and a Housing element.
- an electrical variable preferably one Electricity, as far as possible loss and / or trouble-free to tap or transmit. Furthermore, should with her electrical quality also a good mechanical Be assured handling and stability.
- band, area or plate-like prepared power take-off devices used.
- These known current collection devices e.g. in Shape of a band, surface or plate-like terminal lug or tab, are also used to seal them e.g. to a To contact current and / or -abstagedes substrate.
- To have these known acceptance devices for electrical Strom a first contact area, with which the Take-off device to a stromzu- or stromablocationder Area is mechanically and electrically contacted.
- a second contact area which is then in use, i. also in the finished product, is electrically connected to a power source or sink.
- For transmitting the electric current between the first Contact area and the second contact area is on Transmission range in the known acceptance devices designed for electric power.
- Switching, transmission or acceptance modules - which hereinafter simply referred to as modules and also So-called diode modules or uncontrolled modules include should - for high currents known Acceptance devices on a flat and planar formed conductor substrate, in particular a DCB / AlN substrate, so soldered that they are essentially project vertically from the conductor substrate.
- the appropriate housing must be suitable Having slots through which the known Threaded electrical power takeoff devices become. Due to its band or plate-like structure can damage the case when the case is slipped on Arrangement of the band or area-like acceptance devices for electric power of the conventional form e.g. by Kink or cancel.
- US-A-5,984,692 discloses a compound chip for stacked circuit boards described which inserted between metallizations of these circuit boards is.
- This connection chip is in its to the level of Circuit boards vertical direction slightly curved so as to intervene between the circuit boards to be provided that a reliable electrical Contact with the metallization is guaranteed.
- the invention has for its object to provide a power semiconductor module, which can be used for the transmission and switching of high currents or load currents and which thereby has an increased mechanical stability.
