Das Verfahren beinhaltet Folgendes: Bereitstellen eines Pin-Fin-Leistungsmoduls und einer Vorrichtung, wobei das Leistungsmodul eine Pin-Fin-Basisplatte, Isoliermaterial, das die Basisplatte und auf dem Isoliermaterial bereitgestellte Leistungschips verbindet, umfasst, die Vorrichtung beinhaltet einen Hauptteil, das eine flache obere Oberfläche und eine flache untere Oberfläche und auf der oberen Oberfläche des Hauptteils vorgesehene Löcher aufweist, wobei die Verteilung der Löcher dieselbe wie die Anordnung der Finnen ist, die Öffnung der Löcher größer als die Abmessung der Finnen ist und die Länge der Löcher nicht kürzer als die der Finnen ist, Einsetzen der Pin-Finnen in die Vorrichtung, so dass sich jede Finne im Inneren des entsprechenden Lochs befindet, Platzieren des mit der Vorrichtung kombinierten Leistungsmoduls in einen Hohlraum zwischen einer oberen Gussform und einer unteren Gussform, während die untere Oberfläche der Vorrichtung auf der oberen Oberfläche dem unteren Gussform platziert wird, Durchführen des Gießprozesses durch Einspritzen von Epoxidharz, Entfernen der Vorrichtung von den Pin-Finnen. Der Druck wird während des Epoxidharzgießens gleichmäßig verteilt, da die flache Oberfläche die untere Gussform kontaktiert, womit das Pin-Fin-Brechen oder -Biegen vermieden werden kann.A method and apparatus for making a pin-fin power module are disclosed. The method includes: providing a pin-fin power module and a device, wherein the power module comprises a pin-fin base plate, insulating material connecting the base plate and power chips provided on the insulating material, the device includes a body that is a flat upper surface and a flat lower surface and having holes provided on the upper surface of the main part, wherein the distribution of the holes is the same as the arrangement of the fins, the opening of the holes is larger than the dimension of the fins and the length of the holes is not shorter than that is, of the fins, inserting the pin fins into the device so that each fin is inside the corresponding hole, placing the power module combined with the device into a cavity between an upper mold and a lower mold, while the lower surface of the fins Device on the upper surface de M is placed in the lower mold, performing the casting process by injecting epoxy resin, removing the device from the pin fins. The pressure is evenly distributed during the epoxy molding because the flat surface contacts the lower mold, thus avoiding pin-fin breaking or bending.

Ausführungsform
Zunächst Bereitstellen eines Pin-Fin-Leistungsmoduls und einer Vorrichtung
Einsetzen des Pin-Fin in die Vorrichtung, wie in
Beziehen wir uns nun auf
Mit der Hilfe der Vorrichtung wird der Druck während des Epoxidharzgießens gleichmäßig verteilt, da eine flache Oberfläche die untere Gussform kontaktiert, womit das DBC-Brechen oder -Biegen vermieden werden kann. Unterdessen werden die Finnen eher unwahrscheinlich unter dem Schutz der Vorrichtung während des Gießprozesses brechen oder biegen.With the aid of the device, the pressure is evenly distributed during epoxy molding because a flat surface contacts the lower mold, thus preventing DBC breakage or bending. Meanwhile, the fins are unlikely to break or bend under the protection of the device during the casting process.
