Definitions
- Power semiconductor modules and relates to a semiconductor module with a housing and with a metallic base plate.
- one or more power semiconductor chips are usually arranged on a substrate and contacted on the back.
- the underside of the substrate is copper-clad and functions as a heat dissipation contact surface in order to be able to dissipate any power losses that occur in the form of heat during operation of the semiconductor components.
- it is equipped with areally connected by soldering.
- This arrangement is surrounded by a frame or (plastic) module housing and can e.g. be pressed onto a heat sink by means of screw connections.
- the generalized term housing is to be understood in the following as meaning both a frame, which can also be part of a multi-part housing, and a module housing.
- the object is achieved in particular by a semiconductor module with a housing and with a metallic base plate in that a mechanically pressure-resistant counterpart is incorporated into the housing, which forms a fixed connection with a pressure-resistant connecting element on the base plate side, and in that the connection is a through opening for fastening the Has semiconductor module on a heat sink.
- an essential aspect of the invention is that the elements used for the connection (counterpart in the housing and base plate-side connection element) are made of mechanically pressure-resistant, preferably metallic material and therefore also absorb the forces generated by the continuous screw connection and can introduce them into the housing without significant material deformation or material flow.
- a preferred embodiment of the semiconductor module according to the invention provides that the base element-side connection element is a rivet element and forms a rivet connection with the counterpart. Rivet connections are easy to handle in terms of production technology and are inexpensive.
- Another embodiment of the semiconductor module according to the invention that is preferred in terms of production engineering provides that the rivet element is formed as an integral component from the base plate material. This can be done particularly advantageously immediately when the base plate is punched out.
- an advantageous development of the invention provides that the counterpart has form-locking elements, in particular knurling, in its peripheral region. As a result, a firm fit of the counterpart is ensured in a particularly simple manner, the counterpart advantageously being able to be injected directly into a housing produced by the injection molding process.
- Figure 2 shows the detail of Figure 1 after forming a riveted joint.
- the semiconductor module shown enlarged in a side view in FIG. 1 is a known arrangement with a large number of individual power semiconductors, not shown, each of which is electrically conductively connected to a conductive layer of a substrate by its rear side.
- the substrate and semiconductor components are surrounded by a frame 1, which is part of a plastic housing 2.
- the housing 2 is screwed to a cooling element (not shown) or a heat sink by means of screw connections in order to dissipate heat loss that occurs during operation from the substrate via a base plate 3 to the heat sink.
- a mechanically pressure-resistant counterpart 4 is embedded, which has been injected with the manufacture of the housing s 2 made of plastic.
- the counterpart like the base plate 3, is preferably made of metal and has 5 form-locking elements 6 in the form of a knurling in its peripheral region. Through this, the counterpart is particularly firmly anchored in the housing 2.
- the base plate 3 has a mechanical pressure and tensile strength
- Connection learning t 10 on This is designed as a pull-through and dimensioned so that it pulls through the counterpart sufficiently to establish a firm connection.
- This connection could basically be formed by the fact that a screw nut which is firmly supported on the counterpart is screwed onto a corresponding external thread on the jacket of the passage 10. It is also conceivable to provide a firm non-positive or material connection between the counterpart and the passage.
- the connection has a through opening 12 for the (screw) fastening of the semiconductor module on a heat sink.
- connection is designed as a fixed rivet connection 14, as shown in FIG.
- the base plate-side connecting element 10 is designed as a rivet element 15, which is formed as an integral part from the base plate material.
- the rivet element forms, with the counterpart 4 designed as a pressure piece, the rivet connection 14.
- the rivet punch 16 used for producing the rivet connection is shown in FIG of the counterpart 4 has pressed.
- this embodiment has the essential advantage that the underside 18 of the base plate remains completely unaffected by the riveting process and remains undeformed and thus, as desired, flat. This has a favorable effect on the heat transfer to the cooling element.
