The invention relates to a power module. The power module has at least one power semiconductor and at least one further electronic component. The power module has a housing which is formed by a shaped body and is formed by an encapsulation compound. According to the invention, the housing is formed in at least two levels. At least one power semiconductor component is arranged in a first level and the at least one further electronic component is arranged in the second level. At least one electrically conductive layer, which forms an electrically conductive connecting structure, is formed on a surface of an inner boundary of the power module which extends between the levels. The connecting structure is applied directly to the surface. The at least one further electronic component is electrically conductively connected, in particular soldered or sintered, to the wiring structure. The power semiconductor  component in the first level is electrically connected to the further component in the second level by means of the connecting structure.

Power module comprising a housing which is formed in levels

An electrical device includes an electrical component that is at least partially covered by a covering material that includes a cement material. The covering material also includes particles having a first material and fibers having a second material. The first material and the second material each possess a higher coefficient of thermal conductivity than the cement of the cement material.

Electrical device having a covering material

The invention relates to an electronic module (), in particular a power module, having at least one electrical/electronic component () and having a housing (), which at least partly extends around the component (), wherein the housing () is made of cement composite (), and wherein the cement composite () has at least one particulate filler (). According to the invention, the particulate filler () has aluminum nitride particles (), which each have a coating only of aluminum oxide ().

Electronic module, method

An abrasive particle includes at most three surfaces and at least one edge which has a corner at at least one end. The abrasive particle may contain a ceramic material, particularly polycrystalline &#x3b1;-AlO. Abrasive particles as a whole, methods for producing abrasive particles, moulds, abrasive articles, methods for producing abrasive articles, and methods for abrading a surface are also disclosed.

Abrasive particle with at most three surfaces and one corner

An abrasive grain includes a surface having at least a first face with a first outline, and at least one second face with a second outline. The first outline does not contain any vertices, but the second outline contains at least one vertex. The abrasive grain may include a ceramic material, especially polycrystalline &#x3b1;-AlO.

Abrasive grain with main surfaces and subsidiary surfaces

An abrasive member includes an abrasive member base and a plurality of abrasive particles applied to the abrasive member base. At least a large proportion of the abrasive particles form an abrasive edge unit with an abrasive edge inclined at an angle between 0&#xb0; and 90&#xb0; relative to a defined working direction.

Abrasive means

An abrasive particle includes at most three surfaces and at least one edge which has a corner at least one end. The abrasive particle may contain a ceramic material, particularly polycrystalline &#x3b1;-AlO. Abrasive particles as a whole, methods for producing abrasive particles, moulds, abrasive articles, methods for producing abrasive articles, and methods for abrading a surface are also disclosed.

Abrasive grain containing a first face without vertices and a second face with vertices

A machine tool, for example a hand-held belt grinder, is subjected to high frequencies outside a working plane between an abrasive belt and a workpiece. In particular, the machine tool is subject to high frequencies in a free-running region of the belt, of an excitation actuator, in particular by a piezo element.
