Abstract
Description
Die Erfindung beschreibt ein Verpackungsbehältnis mit Leistungshalbleitermodulen zu deren inner- und / oder außerbetrieblichen Transport. Moderne Leistungshalbleitermodule, speziell mit Leistungstransistoren wie IGBT (insulated gate bipolar transistor) oder MOS-FET (metal oxid semiconductor field effect transistor) sind sehr empfindliche gegenüber Berührungen durch die menschliche Hand, weil sich hierdurch elektrostatische Felder auf die Kontaktelemente entladen können und die Leistungstransistoren vorschädigen oder zerstören können. Weiterhin sind jegliche Art von Verschmutzungen beispielhaft der Kontaktelemente oder speziell bei grundplattenlosen Leistungshalbleitermodulen auch der Substratunterseite nachteilig. Hierbei wird die elektrische Kontaktsicherheit im späteren Betrieb beeinträchtigt. Substratunterseiten, speziell wenn sie bereits vor dem Transport mit einer pastösen wärmeleitfähigen Schicht versehen sind, bedürfen ebenfalls eines Schutzes vor Berührung und / oder Verunreinigung.The invention describes a packaging container with power semiconductor modules for their internal and / or external transport. Modern power semiconductor modules, especially with power transistors such as IGBT (insulated gate bipolar transistor) or MOS-FET (metal oxide semiconductor field effect transistor) are very sensitive to touch by the human hand, because this can discharge electrostatic fields on the contact elements and damage the power transistors or destroy. Furthermore, any type of contamination by way of example of the contact elements or, especially in the case of baseplate-free power semiconductor modules, also of the underside of the substrate is disadvantageous. In this case, the electrical contact safety is impaired in later operation. Substrate surfaces, especially if they are already provided with a pasty thermally conductive layer before transport, also require protection against contact and / or contamination.

Die vorliegende Erfindung hat die Aufgabe ein Verpackungsbehältnis mit mindestens einem Leistungshalbleitermodul für deren inner- und / oder außerbetrieblichen Transport zu schaffen, das gegen Verunreinigungen empfindliche Oberflächen und / oder sonstige Teile des Leistungshalbleitermoduls und / oder gegen elektrostatische Felder empfindliche Kontaktelemente des Leistungshalbleitermoduls schützt sowie eine mehrfache Nutzung dieses Verpackungsbehältnisses erlaubt.The object of the present invention is to provide a packaging container with at least one power semiconductor module for its internal and / or external transport which protects surfaces sensitive to contamination and / or other parts of the power semiconductor module and / or contact elements of the power semiconductor module which are sensitive to electrostatic fields and a multiple Use of this packaging container allowed.
Die Aufgabe wird gelöst durch ein Verpackungsbehältnis mit den Merkmalen des Anspruchs 1. Bevorzugte Weiterbildungen finden sich in den Unteransprüchen.The object is achieved by a packaging container with the features of claim 1. Preferred developments can be found in the dependent claims.
Der Grundgedanke des erfindungsgemäßen Verpackungsbehältnisses mit mindestens einem Leistungshalbleitermodul geht aus von mindestens einem Formkörper. Dieser Formkörper weist eine Wandung sowie eine vorzugsweise vollständig geschlossene Deckfläche auf. Die Wandung ist in mehrere Wandungsabschnitte unterteilt. An mindestens zwei gegenüberliegenden Wandungsabschnitten ist je eine Abstützkante oder an mindestens drei Stellen der Wandung je eine Abstützfläche angeordnet. Diese Abstützkanten oder Abstützflächen bilden eine Auflage für bestimmte Teile des Leistungshalbleitermoduls derart, dass eine Berührung des Leistungshalbleitermoduls mit der Deckfläche des Formkörpers verhindert ist. Weiterhin liegt das Leistungshalbleitermodul zumindest teilweise an Wandungsabschnitten an, oder ist zumindest eng benachbart hierzu angeordnet, was hier synonym verwendet wird. Alternativ und zusätzlich weist das Verpackungsbehältnis an der Deckfläche des Formkörpers mindestens eine Stütze auf. Diese Stütze erstreckt sich von der Deckfläche in das Innere des Formkörpers, wobei es sich von der Deckfläche aus ins Innere hinein verjüngt und sich teilweise in eine Aussparung des Leistungshalbleitermoduls hinein erstreckt und hierdurch eine Berührung des Leistungshalbleitermoduls mit der Deckfläche verhindert.The basic idea of the packaging container according to the invention with at least one power semiconductor module is based on at least one molded body. This shaped body has a wall and a preferably completely closed cover surface. The wall is divided into several wall sections. At least two opposite wall sections each have a support edge or arranged at least three locations of the wall depending on a support surface. This support edges or support surfaces form a support for certain parts of the power semiconductor module such that contact of the power semiconductor module is prevented with the top surface of the molding. Furthermore, the power semiconductor module is at least partially at wall sections, or at least closely adjacent thereto arranged what is used synonymously here. Alternatively and additionally, the packaging container has at least one support on the top surface of the shaped body. This support extends from the top surface into the interior of the molded body, wherein it tapers from the top surface into the interior and partially extends into a recess of the power semiconductor module and thereby prevents contact of the power semiconductor module with the top surface.
Nachfolgend werden die Merkmale und Ausgestaltungen der Erfindung anhand der
Die Wandung des Bodenteils (100a) besteht aus vier rechteckig angeordneten Wandungsabschnitten (110a). Hierbei weisen zwei einander gegenüberliegende Wandungsabschnitte (110a) je eine Abstützkante (112) auf. Weiterhin weist das Bodenteil (100a) eine geschlossene Deckfläche, den Boden (120a), auf. Die gegenüberliegende Seite ist offen gestaltet um ein Leistungshalbleitermodul (200) in dieses Bodenteil (110a) einlegen zu können. Dieses Leistungshalbleitermodul (200) besteht aus einem Kunststoffgehäuse (202) und weist auf der dem Boden (120a) zugewandten Seite (220) metallische Anschlusselemente (222) auf. Diese Anschlusselemente (222) sollen zu ihrem Schutz nicht mit dem Verpackurigsbehältnis in Berührung kommen. Daher liegt das Leistungshalbleitermodul (200) mit einem Teil seines Gehäuses (202) auf den Abstützkanten (112a) auf. Weiterhin liegt das Gehäuse (202) des Leistungshalbleitermoduls (200) teilweise an den Wandungsabschnitten (110a) an oder weist nur einen geringen Abstand hiervon auf, was hier als synonym betrachtet wird. Die Abstützkanten (112) müssen in ihrer Flächenausdehnung folglich derart ausgebildet sein, dass durch eine geringfügige horizontale Lageänderung auf Grund des Abstandes des Leistungshalbleitermoduls (200) zu den Wandungsabschnitten (110a) ein Abrutschen des Leistungshalbleitermoduls (200) von den Abstützkanten (112) nicht möglich ist. Somit ist ein Kontakt der Anschlusselemente (222) des Leistungshalbleitermodul (200) mit dem Verpackungsbehältnis wirksam verhindert. Ein Verpackungsbehältnis wie bisher beschrieben ist in den meisten Fällen für den innerbetrieblichen Transport ausreichend.The wall of the bottom part (100a) consists of four rectangularly arranged wall sections (110a). Here, two mutually opposite wall sections (110a) each have a supporting edge (112). Furthermore, the bottom part (100a) has a closed cover surface, the bottom (120a). The opposite side is designed to be open to insert a power semiconductor module (200) in this bottom part (110a) can. This power semiconductor module (200) consists of a plastic housing (202) and has metallic connection elements (222) on the side (220) facing the bottom (120a). These connection elements (222) should not come into contact with the Verpackurigsbehältnis for their protection. Therefore, the power semiconductor module (200) rests with a part of its housing (202) on the supporting edges (112a). Furthermore, the housing (202) of the power semiconductor module (200) partly rests on the wall sections (110a) or has only a slight distance therefrom, what is considered synonymous here. The support edges (112) must therefore be formed in their surface extent such that slipping of the power semiconductor module (200) from the supporting edges (112) is not possible by a slight horizontal change in position due to the distance of the power semiconductor module (200) to the wall sections (110a) is. Thus, contact of the connection elements (222) of the power semiconductor module (200) with the packaging container is effectively prevented. A packaging container as described so far is sufficient in most cases for in-house transport.
Für den außerbetrieblichen Transport weist das Verpackungsbehältnis vorzugsweise noch ein zweites Formteil (100b), das Deckelteil, auf. Dieses Deckelteil besteht ebenfalls aus vier rechteckig angeordneten Wandungsabschnitten (110b). Weiterhin weist das Deckelteil (100b) eine geschlossene Deckfläche, den Deckel (120b), auf. Das hier beschriebene Leistungshalbleitermodul (200) weist eine zentral gelegene Ausnehmung (214), eine Befestigungbohrung (vgl.
Das dargestellte Leistungshalbleitermodul (200) weist auf seiner dem Deckel (110b) zugewandten Seite, also auf dem Substrat (210) eine wärmeleitfähige pastöse Schicht auf, eine Wärmeleitpaste (212) nach dem Stand der Technik. Diese muss vor Berührungen und Verschmutzung geschützt sein. Dies wird ebenfalls mit dem hier vorgestellten Deckelteil (100b) erreicht. Das Deckelteil (100b) liegt nur mit der geringen Fläche der in ihm ausgebildeten Stütze (122) am Leistungshalbleitermodul (200) an und somit auch nur dort an der Wärmeleitpaste (212) an. Das Deckelteil (100b) schützt in Verbindung mit dem Bodenteil (100a) die Anschlusselemente (222) und die Wärmeleitpaste (212) und somit das gesamte Leistungshalbleitermodul (200) für inner- und außerbetrieblichen Transport ausreichend.The illustrated power semiconductor module (200) has on its side facing the cover (110b), ie on the substrate (210), a thermally conductive pasty layer, a thermal paste (212) according to the prior art. This must be protected against contact and contamination. This is also achieved with the cover part (100b) presented here. The cover part (100b) rests against the power semiconductor module (200) only with the small area of the support (122) formed in it, and thus only against the thermal compound (212) there. The cover part (100b) in conjunction with the bottom part (100a) sufficiently protects the connection elements (222) and the thermal compound (212) and thus the entire power semiconductor module (200) for internal and external transport.
Der Schutz gegen Verunreinigungen des gesamten Leistungshalbleitermoduls (200) wird sichergestellt, indem das Verpackungsbehältnis ein Deckelteil (100b) aufweist, das mit dem Bodenteil (100a) über ein weiteres Formteil (300) einstückig verbunden ist. Es ergibt sich somit ein Verpackungsbehältnis das durch das weitere als Scharnier, mit einer Drehachse in Richtung der Zeichenebene, wirkende Formteil (300) einfach zu verwenden ist. Vorteilhaft an dieser Ausgestaltung des Verpackungsbehältnis ist, dass es durch eine umlaufende Versiegelung gasdicht verschlossen werden kann und somit einen idealen Schutz für den außerbetrieblichen Transport eines Leistungshalbleitermoduls (200) darstellt.The protection against contamination of the entire power semiconductor module (200) is ensured by the packaging container having a lid part (100b) which is integrally connected to the bottom part (100a) via another mold part (300). This results in a packaging container which is easy to use due to the further shaped part (300) acting as a hinge with a rotation axis in the direction of the plane of the drawing. An advantage of this embodiment of the packaging container is that it can be closed gas-tight by a peripheral seal and thus represents an ideal protection for the external transport of a power semiconductor module (200).
Das Deckelteil (100b) ist ausgestaltet mit einer rechteckigen Wandung, wobei hier alle vier Wandungsabschnitte (110b) Abstützkanten (112) aufweisen und das Leistungshalbleitermodul (200) im Bereich zwischen den Abstützkanten (112) und der Öffnung des Deckelteils (100b) an den Wandungsabschnitten (110b) anliegt. Die Abstützkanten (112) gewährleisten, dass der Deckel (110b) keine Kontaktstellen mit den Anschlusselementen (222) des Leistungshalbleitermoduls (200) aufweist.The cover part (100b) is configured with a rectangular wall, wherein here all four wall sections (110b) have support edges (112) and the power semiconductor module (200) in the area between the support edges (112) and the opening of the cover part (100b) at the wall sections (110b) is present. The support edges (112) ensure that the cover (110b) has no contact points with the connection elements (222) of the power semiconductor module (200).
Das Deckelteil (100b) des Verpackungsbehältnisses ist wiederum wie in
Ein nicht dargestelltes Verpackungsbehältnis für als Scheibenzelle ausgebildetes Leistungshalbleitermodul (200) weist mindestens drei vorzugweise in einem gleichseitigen Dreieck an einer kreisförmigen Wandung (110a) angeordnete Abstandsflächen (114) auf, auf denen das Gehäuse der Scheibenzelle aufliegt.A packaging container (not shown) for a power semiconductor module (200) designed as a disk cell has at least three spacer surfaces (114) preferably arranged in an equilateral triangle on a circular wall (110a), on which the housing of the disk cell rests.
