Besonders bevorzugt ist es, wenn beide elastische Druckkörper aus dem gleichen Werkstoff bestehen.The main body can consist of an insulating material, preferably a high-temperature resistant, preferably thermoplastic, plastic, in particular polyphenylene sulfide. Alternatively, the base body may also consist of a metal molding. The elastic pressure bodies may consist of an elastomer, preferably a silicone elastomer, in particular a crosslinked liquid silicone. It is particularly preferred if both elastic pressure bodies consist of the same material.
Es ist besonders bevorzugt, wenn der erste elastische Druckkörper eine größere wirksame Höhe aufweist als der zweite elastische Druckkörper. Unter der wirksamen Höhe soll diejenige verstanden werden in die für die Deformation des elastischen Druckkörpers zur Verfügung steht. Dies ist insbesondere diejenige Höhe die über die umgebende Oberfläche des Grundkörpers hervorsteht, bzw. aus dem Grundkörper herausragt.It is particularly preferred if the first elastic pressure body has a greater effective height than the second elastic pressure body. The effective height should be understood to mean that in which there is available for the deformation of the elastic pressure body. This is in particular that height which projects beyond the surrounding surface of the main body, or protrudes from the main body.
Es kann auch vorteilhaft sein, wenn das Gehäuse erste Führungselemente und die Druckeinrichtung zweite Führungselemente aufweist, wobei diese ersten und zweiten Führungselemente zueinander korrespondierend angeordnet und dazu ausgebildet sind eine Bewegung der Druckeinrichtung zum Gehäuse in Normalenrichtung zu führen.It can also be advantageous if the housing has first guide elements and the pressure device has second guide elements, wherein these first and second guide elements are arranged corresponding to one another and designed to move the pressure device toward the housing in the normal direction.
Die erfindungsgemäße Anordnung ist ausgebildet mit einem oben beschriebenen Leistungshalbleitermodul, mit einer Kühleinrichtung und mit einem Befestigungsmittel, wobei das Befestigungsmittel in die Befestigungseinrichtung, die Teil des Gehäuses ist, eingreift und somit das Leistungshalbleitermodul auf der Kühleinrichtung fixiert und das Gehäuse einen ersten Druck auf den ersten elastischen Druckkörper ausübt, der zweite elastischer Druckkörper diesen Druck als zweiten Druck auf das Substrat überträgt und somit schließlich das Substrat mittels eines dritten Drucks auf die Kühleinrichtung gedrückt wird.The inventive arrangement is formed with a power semiconductor module described above, with a cooling device and with a fastening means, wherein the fastening means engages in the fastening device which is part of the housing, and thus fixes the power semiconductor module on the cooling device and the housing a first pressure on the first elastic pressure body exerts, the second elastic pressure body transmits this pressure as a second pressure on the substrate and thus finally the substrate is pressed by means of a third pressure on the cooling device.
Hierbei kann der Druck des zweiten elastischen Druckkörpers auf das Substrat mittelbar ausgeübt werden, indem der Druck auf Verbindungseinrichtung ausgeübt wird.In this case, the pressure of the second elastic pressure body can be exerted indirectly on the substrate by the pressure is exerted on connecting means.
Es kann aber auch der Druck des zweiten elastischen Druckkörpers auf das Substrat unmittelbar ausgeübt werden.However, it is also possible for the pressure of the second elastic pressure body to be exerted directly on the substrate.
Bevorzugt ist es, wenn zwischen Substrat und der Kühleinrichtung eine Wärmeleitpaste mit einer Dicke von weniger als 20µm, insbesondere von weniger als 10µm, insbesondere von weniger als 5µm angeordnet ist.It is preferred if between the substrate and the cooling device, a thermal paste with a thickness of less than 20 .mu.m, in particular less than 10 .mu.m, in particular less than 5 .mu.m is arranged.
Bevorzugt ist es weiterhin, wenn das Gehäuse des Leistungshalbleitermoduls mindesten einen Zapfen aufweist, der in einer zugeordneten Ausnehmung der Kühleinrichtung hineinragt und dazu ausgebildet ist ein Verdrehen des Gehäuses gegen die Kühleinrichtung zu verhindern.It is furthermore preferred if the housing of the power semiconductor module has at least one pin which projects into an associated recess of the cooling device and is designed to prevent the housing from rotating against the cooling device.
