Description
Die Erfindung betrifft das Gebiet der ultraschallbasierten Fertigungsverfahren, insbesondere Ultraschallschweißen (Bonden). The invention relates to the field of ultrasound-based manufacturing processes, in particular ultrasonic welding (bonding).
Für empfindliche Bauteile, wie dies zum Beispiel für Leistungshalbleitermodule der Fall ist, werden hohe Anforderungen an die eingesetzten Verbindungsprozesse gestellt. Neben einer hohen Wirtschaftlichkeit und damit kurzen Prozesszeiten werden Verfahren eingesetzt, die einen geringen Wärmeeintrag in die Bauteile verursachen. Thermisch empfindliche Bauteile werden dadurch vor Beschädigungen geschützt. Für derart komplexe Anforderungen eignet sich das Ultraschallschweißen, da es sich durch kurze Prozesszeiten und geringen Wärmeeintrag auszeichnet. Die Prozesszeiten können dabei je nach Anwendung auch unter einer Sekunde liegen. Die an der Sonotrode anliegende hochfrequente Schwingung wird auf die Fügepartner übertragen, welche sich anschließend lokal stark erwärmen und sich dadurch verbinden. Die Prozessparameter der heute eingesetzten Ultraschall-Verbindungsprozesse werden im statischen Systemzustand eingestellt. Hierzu zählen im Wesentlichen die Anpresskraft, die normal zur Oberfläche der Fügestelle wirkt, die Amplitude der Ultraschallschwingung und die Prozessdauer. Da die Ultraschallprozesse einer hohen Dynamik unterliegen, ist die Parametereinstellung im statischen Zustand in manchen Anwendungen eine unzureichende Lösung, um reproduzierbare Ergebnisse auch bei komplexen Fügevorgängen zu gewährleisten. Zudem ist eine Anpassung der Prozessparameter, im Speziellen der Anpresskraft, während des Fügeprozesses schwierig. Eine Regelung der Anpresskraft während des Ultraschallprozesses ist nicht möglich. Die Anpresskraft wird in der Folge auch als Prozesskraft bezeichnet. For sensitive components, as is the case, for example, for power semiconductor modules, high demands are placed on the connection processes used. In addition to high efficiency and thus short process times, methods are used which cause a low heat input into the components. Thermally sensitive components are thus protected from damage. For such complex requirements, the ultrasonic welding is suitable, since it is characterized by short process times and low heat input. Depending on the application, the process times can also be under one second. The high-frequency oscillation applied to the sonotrode is transmitted to the joining partners, which then locally heat up strongly and thereby connect. The process parameters of the ultrasound connection processes used today are set in the static system state. These include essentially the contact force, which acts normal to the surface of the joint, the amplitude of the ultrasonic vibration and the duration of the process. Since the ultrasound processes are subject to high dynamics, the static parameter setting is in some applications an insufficient solution to ensure reproducible results even in complex joining processes. In addition, an adaptation of the process parameters, in particular the contact pressure, during the joining process difficult. A regulation of the contact pressure during the ultrasonic process is not possible. The contact force is referred to as process force in the sequence.
Eine der Erfindung zugrunde liegende Aufgabe ist, eine Vorrichtung für einen ultraschallbasierten Fertigungsprozess so zu gestalten, dass Prozessparameter wie z.B. die Anpresskraft besser überwacht und bei Bedarf beeinflusst werden können. An object underlying the invention is to design an apparatus for an ultrasound-based manufacturing process such that process parameters such as e.g. the contact pressure can be better monitored and influenced if necessary.
Diese Aufgabe wird durch eine Vorrichtung gemäß Anspruch 1 oder mit einem Verfahren gemäß dem Anspruch 12 gelöst. Unterschiedliche Ausführungsbeispiele und Weiterentwicklungen der Erfindung sind Gegenstand der abhängigen Ansprüche. This object is achieved by a device according to
