Elektrisches Bauelement und Verfahren zur Anbringung einer elektrischen Verdrahtungsanordnung,Electrical component and method for attaching an electrical wiring arrangement,
Die Erfindung betrifft ein elektrisches Bauelement und ein Verfahren zur Anbringung einer elektrischen Verdrahtungsanordnung» The invention relates to an electrical component and a method for attaching an electrical wiring arrangement »
Ein elektrisches Bauelement gemäß der Erfindung ist gekennzeichnet durch die Kombination einer elektrischen Verdrahtungsanordnung mit Keramiksubstrat mit einem starren, thermisch leitenden Trägerteil und einer zwischengeschalteten Lage aus viskoelastischem Material, das klebend sowohl mit dem Substrat als auch mit dem Trägerteil verbunden ist.An electrical component according to the invention is characterized by combining an electrical wiring arrangement with a ceramic substrate with a rigid, thermally conductive carrier part and an intermediate layer of viscoelastic material, which is adhesively connected both to the substrate and to the carrier part.
Das Verfahren gemäß der Erfindung zur Anbringung einer elektrischen Verdrahtungsanordnung mit einem oder mehreren Leitern, die auf einem Keramiksubstrat sitzen, ist dadurch gekennzeichnet, daß eine zwischengeschaltete Lage aus viskoelastischem Material klebend an dem Substrat und an einem starren, thermisch leitenden Trägerteil angebracht wird.The method according to the invention for applying an electrical Wiring arrangement with one or more conductors, which sit on a ceramic substrate, is characterized in that an interposed Layer of viscoelastic material adhesively attached to the substrate and to a rigid, thermally conductive carrier part will.
Die Erfindung ist nachstehend an Hand der Zeichnung näher erläutert, in der ein Schnitt durch eine Verdrahtungsanordnung und einer zugehörigen Befestigung gezeigt ist.The invention is explained in more detail below with reference to the drawing, in which a section through a wiring assembly and an associated attachment is shown.
Eine Verdrahtungsanordnung 10 weist einen sogenannten gedruckten Dickfilm-Schaltkreis auf, der dadurch entsteht, daß ein Muster aus metallischer Farbe auf ein Keramiksubstrat 11 aufgebrannt wird. Auf dem Substrat 11 können im übrigen mehrere Leiterlagen vorgesehenA wiring arrangement 10 includes a so-called thick film printed circuit, which is formed by firing a pattern of metallic paint onto a ceramic substrate 11. A plurality of conductor layers can also be provided on the substrate 11

sein, die an bestimmten Punkten miteinander verbunden sind, ansonsten aber gegenseitig isoliert sind.that are connected to each other at certain points, otherwise but are mutually isolated.
Sin Trägerteil 12 besteht aus zwei wannenförmigen Aluminiumplatten 1J, 14» die innerhalb eineander liegen und durch eine Lage aus yiskoelastischem Η-Kleber miteinander verbunden sind. Der Teil 12 ist mit Löchern 16 versehen, mittels derer er an einem zugehörigen Konstruktionsteil 17 angebracht ist. Das Substrat 11 ist klebend an einer viskoeleastischen Lage 18 angebracht, bestehend aus einer Lage K'itreilgummie mit einem Vert von 75 auf der Internationalen Guruni-Härteskala. Die Lage 18 ist ebenfalls innerhalb der V/annenpartie am Teil 12 befestigt. Ein geeigneter Kleber für diesen Zweck ist ein Epoxydharzkleber. Verbindungen zwischen der Verärahtungsanordnung und zugehörigen außenllegenden Teilen werden durch flexible Verbindungen 19 hergestellt.Sin carrier part 12 consists of two trough-shaped aluminum plates 1J, 14 »which lie within each other and through a layer of yiskoelastic Η-glue are connected to each other. The part 12 is provided with holes 16 by means of which it is attached to an associated structural part 17 is attached. The substrate 11 is adhesively attached to a viscoelastic layer 18, consisting of one layer K'itreil rubber with a Vert of 75 on the International Guruni Hardness Scale. The layer 18 is also fastened to the part 12 within the V / annenpartie. A suitable glue for this purpose is an epoxy resin adhesive. Connections between the wiring arrangement and associated external parts are made by flexible connections 19 manufactured.
Die Lagen I5» 18 sind etwa 0,01 ma bzw.OJ 55 mm dick und bestehen aus einem Material, das eine viskosie Eigenschaft beibehält, so daß relative Bewegungen zwischen deia Substrat 11 und den Platten 13» 14 in ihren eigenen Ebenen ein Scheren des Materials der Lagen I5, 16 bewirkt. Dieses Material ist gleichzeitig kohäsiv. Die Lagen 15» 1ö schaffen damit ein hohes Maß an Dämpfung gegenüber Erschütterungen, denen die Konstruktion 17 unterzogen wird, und sie bilden einen Schutz für die Verbindungen 19 und die Bauteile auf dem SubstratThe layers I5 »18 are about 0.01 ma or OJ 55 mm thick and consist of a material that retains a viscous property, so that relative movements between the substrate 11 and the plates 13» 14 in their own planes cause a shearing of the Material of the layers I5, 16 causes. This material is cohesive at the same time. The layers 15 »10 thus create a high degree of damping against vibrations to which the structure 17 is subjected, and they form a protection for the connections 19 and the components on the substrate
Die Lagen I5» 18 haben gute wärmeleitende Eigenschaften, so daß die Anbringung für einen Wärmefließweg sorgt, und zwar für die Wärme, die an der Verdrahtungsanordung 10 entsteht. Die elastische Eigenschaft der Lage 18 nimmt eine unterschiedliche V/ärmeausdehnung zwischen dein Substrat 11 und dem Teil 12 auf. Die Anordnung isoliert ferner die elektrischen Stromkreise vor Spannungen als Folge eines Biegens während der Monate und im Betrieb.The layers I5 »18 have good heat-conducting properties, so that the Attachment provides a heat flow path, namely for the heat that is generated on the wiring arrangement 10. The elastic property The layer 18 absorbs a different thermal expansion between the substrate 11 and the part 12. The arrangement is isolated furthermore, the electrical circuits from stresses as a result of bending during months and during operation.
