Beschreibung der AusführungsbeispieleDescription of the embodiments

Fig. 1 zeigt in einer Seitenansicht eine als Dick­ schicht-Hybridbaugruppe ausgelegte Hybridbaugruppe mit einigen lediglich angedeuteten Bauelementen 2. Die Hybridbaugruppe 1 ist auf eine als Kühlkörper 3 dienende Unterlage aufgebracht, beispielsweise ge­ klebt. An diese Hybridbaugruppe ist eine flexible Leiterplatte 4 herangeführt, deren an die Hybridbau­ gruppe angrenzende Bereiche ebenfalls mit dem Kühl­ körper 3 verklebt sind. Fig. 1 shows a side view of a hybrid module designed as a thick-layer hybrid assembly with some components 2 only indicated. The hybrid assembly 1 is applied to a base serving as a heat sink 3 , for example ge glued. At this hybrid assembly, a flexible circuit board 4 is introduced, the areas adjacent to the hybrid assembly are also glued to the cooling body 3 .

Die flexible Leiterplatte 4 besteht hier beispiels­ weise aus einer Trägerfolie 5, einer Kupferfolie 6 sowie einer Deckfolie 7.The flexible printed circuit board 4 consists here, for example, of a carrier film 5 , a copper film 6 and a cover film 7 .

In Fig. 1 sind auch zwei von dem Kühlkörper ausge­ hende, durch die Leiterplatte 4 hindurchragende, als Justiereinrichtung dienende Fangstifte 8 erkennbar.In Fig. 1, two of the heat sink starting from, protruding through the circuit board 4 , serving as an adjustment device catch pins 8 can be seen .

Von der flexiblen Leiterplatte 4 gehen Anschlußfah­ nen 9 aus, die auf der Hybridbaugruppe 1 enden.From the flexible printed circuit board 4 , connecting grooves 9 start , which end on the hybrid assembly 1 .

In Fig. 2 sind gleiche Teile mit gleichen Bezugszei­ chen versehen, so daß auf deren Beschreibung verzich­ tet werden kann. In Fig. 2 ist erkennbar, daß die Leiterplatte 4 einen Auschnitt 10 aufweist, in dem die Hybridbaugruppe 1 angeordnet ist. Es sind mehrere Kontaktflächen 11 der Hybridbaugruppe 1 angedeutet, auf denen die Anschlußfahnen 9 der flexbilen Leiter­ platte 4 zu liegen kommen. Aus der Draufsicht ist er­ kennbar, daß die Fangstifte 8 in zugehörige Fanglö­ cher 12 in der flexiblen Leiterplatte passen. Durch die aus Fangstift und Fangloch bestehende Justierein­ richtung werden die Anschlußfahnen 9 der flexiblen Leiterplatte genau auf die Kontaktflächen 11 der Hy­ bridbaugruppe ausgerichtet.In Fig. 2, the same parts are provided with the same reference numerals, so that their description can be waived. In Fig. 2 it can be seen that the circuit board 4 has a cutout 10 in which the hybrid assembly 1 is arranged. There are several contact surfaces 11 of the hybrid assembly 1 indicated, on which the terminal lugs 9 of the flexible printed circuit board 4 come to rest. From the top view, it can be seen that the catch pins 8 fit into associated catch holes 12 in the flexible printed circuit board. Due to the Justierein device consisting of a catch pin and catch hole, the connecting lugs 9 of the flexible printed circuit board are aligned precisely with the contact surfaces 11 of the hybrid assembly.

In Fig. 3 sind eine Anschlußfahne 9 der flexiblen Leiterplatte 4 sowie eine Kontaktfläche 11 der Hybridbaugruppe 1 vergrößert dargestellt. Erkennbar ist hier auch eine Ausnehmung bzw. ein Loch 13 in der Anschlußfahne 9.In Fig. 3, a terminal lug 9 of the flexible circuit board 4 and a contact surface 11 of the hybrid assembly 1 are shown enlarged. A recess or a hole 13 in the connecting lug 9 can also be seen here .

Nachdem die Hybridbaugruppe 1 auf dem Kühlkörper 3 festgeklebt wurde, wird die flexible Leiterplatte auf dem Kühlkörper aufgebracht und durch die Justiereinrichtung bzw. die Fangstifte 8 und -löcher 12 genau ausgerichtet. Dadurch liegen die An­ schlußfahnen 9 so auf den Kontaktflächen 11 der Hy­ bridbaugruppe 1, daß durch ein Bügel-Lötverfahren eine elektrische Verbindung hergestellt werden kann. Dabei werden in einem Arbeitsgang mehrere An­ schlußfahnen 9 mit den zugehörigen Kontaktflächen gleichzeitig verbunden. Anschließend ist eine Sichtkontrolle der Kontaktstellen ohne weiteres mög­ lich, wobei aufgrund der Löcher 13 in den An­ schlußfahnen 9 der Lötfluß an den Kontaktstellen sehr leicht kontrolliert werden kann.After the hybrid assembly 1 has been glued to the heat sink 3 , the flexible printed circuit board is applied to the heat sink and precisely aligned by the adjusting device or the catch pins 8 and holes 12 . As a result, the circuit flags 9 are so on the contact surfaces 11 of the hybrid assembly 1 that an electrical connection can be made by a bracket soldering process. Here, several flags 9 are connected to the associated contact surfaces simultaneously in one operation. Subsequently, a visual inspection of the contact points is easily possible, whereby the soldering flux at the contact points can be checked very easily due to the holes 13 in the connecting flags 9 .

In der Seitenansicht in Fig. 4, in der wiederum gleiche Teile mit gleichen Bezugszeichen versehen sind, ist ein Halterahmen 14 erkennbar, der auf die Fangstifte 8 aufgesetzt und mit diesen beispielsweise durch Verlöten verbunden ist. Der Halterahmen dient einerseits als Schutz der elektrischen Verbindungen bzw. der Hybridbaugruppe und andererseits als Zugent­ lastung der elektrischen Verbindungen. Die Zugentla­ stung kann durch Verkleben des Halterahmens 14 mit der flexiblen Leiterplatte 4 erreicht werden. Es ist jedoch auch möglich, durch Vorsprünge auf dem Hal­ terahmen und entsprechende Ausnehmungen in der flexi­ blen Leiterplatte einen Formschluß und damit eine Zugentlastung zu erreichen. Durch die gestrichelte Linie ist angedeutet, daß ein zusätzlicher Schutz der Hybridbaugruppe und/oder elektrischen Verbindung durch ein Gel 15 erreicht werden kann, das in den In­ nenraum des Halterahmens eingegossen wird. Das Gel verhindert, daß Umwelteinflüsse die elektrischen Ver­ bindungen oder die Bauelemente 2 der Hybridbaugruppe 1 beeinträchtigen.In the side view in FIG. 4, in which the same parts are again provided with the same reference numerals, a holding frame 14 can be seen which is placed on the catch pins 8 and connected to them, for example by soldering. The holding frame serves on the one hand to protect the electrical connections or the hybrid assembly and on the other hand to relieve the strain on the electrical connections. The Zugentla stung can be achieved by gluing the holding frame 14 to the flexible circuit board 4 . However, it is also possible to achieve a positive fit and thus strain relief by means of projections on the hal frame and corresponding recesses in the flexi ble circuit board. The dashed line indicates that additional protection of the hybrid assembly and / or electrical connection can be achieved by a gel 15 , which is poured into the interior of the holding frame. The gel prevents environmental influences from affecting the electrical connections or the components 2 of the hybrid assembly 1 .

In den Fig. 1 und 4 ist die Hybridbaugruppe auf die Oberfläche des Kühlkörpers 3 aufgeklebt. Es ist jedoch auch möglich, eine Vertiefung in den Kühl­ körper, der beispielsweise auch aus Druckguß herge­ stellt werden kann, einzubringen, und die Hybridbau­ gruppe in diese Vertiefung einzukleben.In Figs. 1 and 4, the hybrid module is glued to the surface of the radiator 3. However, it is also possible to introduce a recess in the cooling body, which can also be produced, for example, from die casting, and to glue the hybrid assembly into this recess.

Die in den Figuren gezeigte flexible Leiterplatte 4 kann direkt in einen verstärkten Bereich übergehen, in dem weitere Bauelemente angeordnet sind. Es ist auch möglich, die flexible Leiterplatte 4 über ge­ eignete Kontaktierungseinrichtungen mit starren Lei­ terplatten zu verbinden. The flexible printed circuit board 4 shown in the figures can pass directly into a reinforced area in which further components are arranged. It is also possible to connect the flexible circuit board 4 via ge suitable contacting devices with rigid Lei terplatten.

Die Herstellung der elektrischen Verbindung wird da­ durch sehr erleichtert, daß durch die Justiereinrich­ tung 8, 12 eine optimale Ausrichtung der Anschlußfah­ nen 9 gegenüber den Kontaktflächen 11 auf der Hybrid­ baugruppe 1 erreicht wird. Die Anschlußfahnen sind die Enden der Kupferleiterbahnen der flexiblen Lei­ terplatte. Die Verbindung mit den Kontaktflächen er­ folgt durch Löten, beispielsweise durch eine Bügel- Lötung, wobei jeweils alle Lötverbindungen einer Seite einer Hybridbaugruppe gleichzeitig hergestellt werden. Für diese Art Verbindung ist beispielsweise auch das Reflow-Lötverfahren geeignet. Das notwendige Lot befindet sich entweder auf den Anschlußfahnen oder auf den Kontaktflächen der Hybridbaugruppe. Es ist jedoch auch möglich, beide Teile mit Lot zu ver­ sehen.The production of the electrical connection is made much easier by the fact that the Justiereinrich device 8 , 12 optimal alignment of the Anschlussfah NEN 9 relative to the contact surfaces 11 on the hybrid assembly 1 is achieved. The connection lugs are the ends of the copper conductor tracks of the flexible circuit board. The connection to the contact areas is made by soldering, for example by ironing, with all solder connections on one side of a hybrid assembly being made at the same time. The reflow soldering method is also suitable for this type of connection. The necessary solder is either on the connection lugs or on the contact surfaces of the hybrid module. However, it is also possible to see both parts with solder.

Durch die einfache Ausrichtung und die einfache Her­ stellung der Verbindung sind großserien-taugliche Fertigungsverfahren mit großer Fertigungssicherheit bei der Herstellung der elektrischen Verbindungen einsetzbar. Die Qualität der Lötverbindung ist ohne Zerstörung der Verbindungsstellen einfach durch Sichtkontrolle durchführbar, wobei durch das Loch 13 in der Anschlußfahne 9 der Lötfluß sehr leicht über­ prüft werden kann.Due to the simple alignment and the simple manufacture of the connection, large-scale production processes with great manufacturing reliability can be used in the manufacture of the electrical connections. The quality of the soldered connection can be carried out by visual inspection without destroying the connection points, and the soldering flow can be checked very easily through the hole 13 in the connecting lug 9 .

Die mit diesem Verfahren herstellbaren elektrischen Verbindungen sind sehr robust, so daß grundsätzlich ein Schutz der Verbindungen nicht erforderlich ist. Bei rauhen Bedingungen ist es jedoch auch möglich, durch den in Fig. 4 dargestellten, oben erwähnten Halterrahmen die Verbindungen und auch die Hybridbau­ gruppe zu schützen.The electrical connections that can be produced with this method are very robust, so that in principle protection of the connections is not necessary. In harsh conditions, however, it is also possible to protect the connections and also the hybrid assembly by the holder frame shown in FIG. 4, mentioned above.
