A housing body, which encloses the power unit and the control unit. Two conductor bars which are led parallel to the substrate of the power unit and the carrier of the control unit and out through the housing body for the power supply to the circuit arrangement of the power unit. Connecting bars, which are led out of the housing body and connected to the circuit arrangement of the power unit and/or the semiconductor components of the control unit, for the application of control signals for the control of the power module and/or to tap off output signals from the power module.
摘要:
In an electronic assembly whose components or circuit components are combined into at least two sub-assemblies or function units, one or more of the sub-assemblies or function units are disposed on a first substrate comprising a first substrate material. The first substrate is in its turn disposed with one or more further sub-assemblies or function units on a second substrate comprising a second substrate material.

A circuit board has a plurality of circuit board layers that are arranged one over the other, and that each include an electrically insulating base material having a glass transition temperature greater than or equal to 170° C. The circuit board layers each further have at least one thermally conductive layer applied to the base material. Several vias extend through respective ones of the circuit board layers to connect thermally conductive layers of different circuit board layers, such that the vias and the thermally conductive layers form a thermally conductive bridge from a topmost circuit board layer to a bottommost circuit board layer.

摘要:
A method for the automated production of circuit carriers, comprising providing a substrate for accommodating electronic components, applying an electrically conductive, metal-containing base structure on the substrate. Electronic components are also provided on the substrate and are connected to each other by the structure. Electrically conductive, metal-containing conductive adhesive structures are applied onto the substrate, and the electronic components are connected to the base structure in an electrically conductive way by the structures. The conductive adhesive structures are optically differentiated from the base structure by a colored electrically conductive, metal-containing conductive adhesive applied onto the substrate in order to produce the conductive adhesive structure. A contrast, which is necessary for the automated optical monitoring of the conductive adhesive structures and the base structure, is established between the conductive adhesive structures and the base structure.

An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.
