Mittels einer derartigen Druckeinrichtung wird das Substrat auf ein Kühlbauteil gedrückt und somit der Wärmeübergang zwischen dem Substrat und dem Kühlbauteil dauerhaft sicher hergestellt. Das elastische Kissenelement dient hierbei der Aufrechterhaltung konstanter Druckverhältnisse bei unterschiedlichen thermischen Belastungen und über den gesamten Lebenszyklus des Leistungshalbleitermoduls.through Such a printing device is the substrate on a cooling member pressed and thus the heat transfer permanently secure between the substrate and the cooling component produced. The elastic cushion element serves to maintain this constant pressure conditions at different thermal Loads and over the entire life cycle of the power semiconductor module.

Nachteilig an den Leistungshalbleitermodulen nach dem bisher genannten Stand der Technik ist, dass dergestalt ausgestalteten Kontaktelemente eine sich aus der Stanzform bedingende vordefinierte Höhe mit einer stumpf-planen Endfläche zur Kontaktierung mit den ihnen zugeordneten Leiterbahnen aufweisen. Die erforderliche Toleranz dern Höhe als auch die jeweils plane Kontaktendfläche bedingen in Verbindung mit der zur Druckkontaktierung dienenden Druckeinrichtung eine geringe Toleranz bezüglich der Druck einleitenden Kräfte, da bei zu hohem Druck die starre Ausformung der Kontaktelemente das Substrat beschädigt werden kann, während bei zu niedrigem Druck die zuverlässige Kontaktierung aller zweiten Kontaktelemente mit der zugeordneten Leiterbahn nicht gewährleistet sein kann.adversely on the power semiconductor modules according to the previously mentioned state The art is that the thus configured contact elements a with predefined height from the die a blunt-plan end face for contacting with the have associated conductor tracks. The required tolerance height as well as the respective flat contact end face condition in connection with the pressure-contacting Pressure device a low tolerance in terms of pressure Introductory forces, because at too high pressure, the rigid shape the contact elements the substrate can be damaged, while at too low pressure the reliable Contacting of all second contact elements with the associated conductor track can not be guaranteed.
Der Erfindung liegt die Aufgabe zugrunde ein Leistungshalbleitermodul in Druckkontaktausführung mit Lastanschlusselementen und ihnen zugeordneten Kontaktelementen zum Substrat vorzustellen, wobei die Kontaktabschnitte der Kontaktelemente weitergebildet sind, um eine Toleranz bezüglich der Druck einleitenden Kräfte zuzulassen als auch die erlaubte Fertigungstoleranz der einzelnen zweiten Kontaktelemente zu erhöhen.Of the Invention is the object of a power semiconductor module in pressure contact design with load connection elements and imagine them associated contact elements to the substrate, wherein the contact portions of the contact elements are further developed to a tolerance to the pressure-inducing forces to allow as well as the allowable manufacturing tolerance of each to increase second contact elements.
Die Aufgabe wird erfindungsgemäß gelöst durch die Maßnahmen der Merkmale des Anspruchs 1. Bevorzugte Ausführungsformen sind in den Unteransprüchen beschrieben.The The object is achieved by the measures of the features of claim 1. Preferred Embodiments are in the subclaims described.
Der erfinderische Gedanke geht aus von einer Anordnung eines Leistungshalbleitermoduls in Druckkontaktausführung auf einem Kühlbauteil mit mindestens einem Substrat, mindestens zwei hierauf angeordneten Leistungshalbleiterbauelementen, einem Gehäuse und nach außen führenden Last- und Steueranschlusselementen. Das Substrat selbst weist einen Grundkörper auf und auf dessen erster, dem Inneren des Leistungshalbleitermoduls zugewandten Hauptfläche Leiterbahnen mit Lastpotential. Weiterhin weist das Substrat vorzugsweise auch mindestens eine Leiterbahn mit Steuerpotential zu Ansteuerung der Leistungshalbleiterbauelemente auf.Of the inventive idea is based on an arrangement of a power semiconductor module in pressure contact design on a cooling component with at least one substrate, at least two arranged thereon Power semiconductor devices, a housing and after outside leading load and control connection elements. The substrate itself has a base body and on the first, facing the interior of the power semiconductor module Main surface tracks with load potential. Further points the substrate preferably also at least one conductor track with control potential for controlling the power semiconductor components.
Das Leistungshalbleitermodul weist weiterhin Lastanschlusselemente mit hoher Stromtragefähigkeit auf, jeweils ausgebildet als Metallformkörper mit einem ersten Kontaktelement, einem bandartigen Abschnitt und mit einer Mehrzahl von diesem ausgehenden zweiten Kontaktelementen auf. Die jeweiligen bandartige Abschnitte sind parallel zur Substratoberfläche und von dieser beabstandet angeordnet. Die zweiten Kontaktelemente, die von dem bandartigen Abschnitt ausgehen, reichen zum Substrat und bilden dort schaltungsgerecht die Kontaktierung der Lastanschlüsse aus. Vorzugsweise kontaktieren sie hierzu auf dem Substrat die Leiterbahnen mit Lastpotential, alternativ auch direkt die Leistungshalbleiterbauelemente.The Power semiconductor module also has load connection elements high current carrying capacity, each formed as Metal shaped body with a first contact element, a band-like section and with a majority of this outgoing second contact elements. The respective band-like sections are parallel to and spaced from the substrate surface arranged. The second contact elements of the band-like Going out section, reach the substrate and form there circuit-oriented contacting the load terminals. Preferably For this purpose, contact the printed circuit boards with load potential on the substrate. alternatively also directly the power semiconductor components.
Erfindungsgemäß weist hierbei das mindestens eine zweite Kontaktelement einen ersten und einen zweiten Kontaktabschnitt auf. In seinem ersten Kontaktabschnitt reicht das Kontaktelement in einem definierten Winkel α zwischen 20 und 80 Grad vom bandartigen Abschnitt an die zugeordnete Leiterbahn. Anschließend an den ersten Kontaktabschnitt weist das Kontaktelement einen zweiten Kontaktabschnitt auf, welcher eine Verformung, weggerichtet vom ersten Kontaktabschnitt, aufweist. Diese Verformung ist vorzugsweise als konvexe Krümmung oder als Falz ausgestaltet. Hierdurch weist das Kontaktelement eine erfindungsgemäß ausgestaltete Kontaktfläche im zweiten Kontaktabschnitt aus, der in Verbindung mit dem ersten Kontaktabschnitt eine Toleranz des zweiten Kontaktelements bezüglich der Druck einleitenden Kräfte ermöglicht und dergestalt eine zuverlässige Kontaktierung ohne Gefahr der Beschädigung des Substrats gestattet.According to the invention In this case, the at least one second contact element has a first and a second contact portion. In his first contact section extends the contact element in a defined angle α between 20 and 80 degrees from the belt-like section to the associated track. Subsequent to the first contact section, the contact element a second contact portion, which a deformation, directed away from first contact portion having. This deformation is preferred designed as a convex curvature or as a fold. hereby the contact element has an inventively designed Contact surface in the second contact portion, which in conjunction with the first contact portion a tolerance of the second contact element with respect to the pressure inducing forces and thus a reliable contact without danger the damage of the substrate allowed.
Bevorzugt bilden weiterhin die Lastanschlusselemente einen Stapel, wobei hierbei zwischen jeweils benachbarten Lastanschlusselementen im Bereich der jeweiligen bandartigen Abschnitte eine isolierende Zwischenlage angeordnet ist.Prefers Furthermore, the load connection elements form a stack, in which case between each adjacent load connection elements in the area the respective ribbon-like sections an insulating intermediate layer is arranged.
