Description
Die Erfindung betrifft ein Elektronikmodul sowie ein Verfahren zur Herstellung eines Elektronikmoduls. The invention relates to an electronic module and to a method for producing an electronic module.
Es ist bekannt, bei Elektronikmodulen mit zumindest zwei Elektronikbauteilen diese Elektronikbauteile mittels einer Leiterplatte miteinander zu verbinden. Je nach Anwendung resultiert dies in aufwendigen, hochdichten Verdrahtungen, um Leitungslängen möglichst kurz und mit einheitlicher Länge auszubilden. Kurze Leitungslängen sind insbesondere bei Hochfrequenzanwendungen relevant. Eine weitere Miniaturisierung ist zunehmend schwierig. It is known to connect these electronic components by means of a printed circuit board in electronic modules with at least two electronic components. Depending on the application, this results in complex, high-density wiring to form cable lengths as short as possible and with a uniform length. Short cable lengths are particularly relevant in high-frequency applications. Further miniaturization is becoming increasingly difficult.
Es ist daher Aufgabe der Erfindung, ein verbessertes Elektronikmodul zu schaffen, bei welchem Elektronikbauteile flexibler miteinander elektrisch kontaktierbar sind. Ferner ist es Aufgabe der Erfindung, ein Verfahren zur Herstellung eines Elektronikmoduls anzugeben, mittels welchem sich ein solches verbessertes Elektronikmodul fertigen lässt. It is therefore an object of the invention to provide an improved electronic module in which electronic components are more flexible electrically contactable with each other. It is another object of the invention to provide a method for producing an electronic module, by means of which such an improved electronic module can be produced.
Diese Aufgabe der Erfindung wird mit einem Elektronikmodul mit in den Anspruch 1 angegebenen Merkmalen sowie mit einem Verfahren zur Herstellung eines Elektronikmoduls mit in den Anspruch 7 angegebenen Merkmalen gelöst. Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den zugehörigen Unteransprüchen, der nachfolgenden Beschreibung und der Zeichnung. This object of the invention is achieved with an electronic module having specified in the claim 1 features and with a method for producing an electronic module with specified in the claim 7 features. Preferred embodiments of the invention will become apparent from the accompanying dependent claims, the following description and the drawings.
Das erfindungsgemäße Elektronikmodul weist einen Schaltungsträger und mindestens zwei oder mehr Elektronikbauteile mit je einer Flachseite auf. Bei dem erfindungsgemäßen Elektronikmodul sind die Elektronikbauteile derart mittels des Schaltungsträgers angeordnet und/oder getragen, dass sich die Flachseiten zumindest zweier der Elektronikbauteile in zueinander schräg, insbesondere quer (d.h. senkrecht), verlaufenden Erstreckungsebenen erstrecken. Auf diese Weise sind bei dem erfindungsgemäßen Elektronikmodul die Elektronikbauteile mit ihren Flachseiten nicht etwa in einer einzigen Ebene nebeneinander angeordnet, was lange Wege und umständliche Layouts zur Folge hat. The electronic module according to the invention has a circuit carrier and at least two or more electronic components, each with a flat side. In the electronic module according to the invention, the electronic components are arranged and / or supported by the circuit carrier in such a way that the flat sides of at least two of the electronic components extend in planes extending obliquely, in particular transversely (that is to say perpendicularly). In this way, in the electronic module according to the invention, the electronic components are not arranged with their flat sides in a single plane next to each other, which has long ways and cumbersome layouts result.
Stattdessen können die Elektronikbauteile bei dem erfindungsgemäßen Elektronikmodul in drei Dimensionen in nahezu beliebiger Orientierung angeordnet sein, so dass lange Leitungswege vermieden werden können. Die erfindungsgemäß möglichen kurzen Leitungswege bei der elektrischen Kontaktierung von Elektronikbauteilen miteinander sind insbesondere in der Hochfrequenztechnologie vorteilhaft, da so Streufelder und/oder Crosstalk vermeidbar sind. Weiterhin können durch die dreidimensionale Anordbarkeit der Elektronikbauteile die Elektronikbauteile räumlich einander sehr nahe angeordnet sein, sodass sich auch der Bauraum des Elektronikmoduls insgesamt reduzieren lässt. Insbesondere lassen sich elektronische Baugruppen oder Module von mehreren Elektronikbauteilen wie insbesondere von Haltleiterchips weiter miniaturisieren. Weiterhin vorteilhaft lässt sich das erfindungsgemäße Elektronikmodul der äußeren Form nach an einen von übrigen Vorrichtungskomponenten vorgegebenen dreidimensionalen Bauraum anpassen. Instead, the electronic components in the electronic module according to the invention in three dimensions may be arranged in almost any orientation, so that long lines can be avoided. The inventively possible short conduction paths in the electrical contacting of electronic components with each other are particularly advantageous in high-frequency technology, since so stray fields and / or Crosstalk can be avoided. Furthermore, due to the three-dimensional arrangeability of the electronic components, the electronic components can be spatially arranged very close to each other so that the installation space of the electronic module as a whole can be reduced. In particular, electronic assemblies or modules of several electronic components such as in particular of semiconductor chips can be further miniaturized. With further advantage, the electronic module according to the invention can be adapted to the outer shape according to a three-dimensional installation space predetermined by other device components.
In einer bevorzugten Weiterbildung des erfindungsgemäßen Elektronikmoduls ist der Schaltungsträger ein Spritzgussteil. Insbesondere lässt sich zunächst das Spritzgussteil fertigen, wobei nachfolgend Elektronikbauteile und Leitungskontakte an dem Spritzgussteil angeordnet werden. Alternativ und ebenfalls bevorzugt lässt sich zunächst eine Anordnung von Leiterbahnen und elektrischen Kontaktierungen fertigen, wonach der Schaltungsträger als Spritzgussteil an die Leiterbahnen und/oder elektrischen Kontaktierungen angespritzt wird. In a preferred embodiment of the electronic module according to the invention, the circuit carrier is an injection molded part. In particular, the injection-molded part can first be produced, with electronic components and line contacts subsequently being arranged on the injection-molded part. Alternatively and also preferably, an arrangement of conductor tracks and electrical contacts can first be produced, after which the circuit carrier is molded onto the conductor tracks and / or electrical contacts as an injection-molded part.
In einer bevorzugten Weiterbildung des erfindungsgemäßen Elektronikmoduls ist der Schaltungsträger mit einem, vorzugsweise regelmäßigen, Polyeder gebildet, welcher mittels der Erstreckungsebenen oder dazu paralleler Ebenen begrenzt ist. Besonders bevorzugt ist der Polyeder ein Würfel. Geeigneter Weise sind die Elektronikbauteile an den Seitenflächen des Polyeders angeordnet, wobei in einer zweckmäßigen Weiterbildung der Erfindung die Elektronikbauteile mittels Leiterbahnen aneinander kontaktiert sind, welche an den Seitenflächen des Polyeders entlang über die Kanten des Polyeders führen. In a preferred development of the electronic module according to the invention, the circuit carrier is formed with a, preferably regular, polyhedron, which is delimited by means of the extension planes or planes parallel thereto. Most preferably, the polyhedron is a cube. Suitably, the electronic components are arranged on the side surfaces of the polyhedron, wherein in an expedient development of the invention the electronic components are contacted by means of conductor tracks which lead along the side surfaces of the polyhedron along the edges of the polyhedron.
Vorzugsweise weist bei dem erfindungsgemäßen Elektronikmodul der Schaltungsträger Durchkontaktierungen auf, welche sich durch den Schaltungsträger hindurch erstrecken und mittels welchen zumindest zwei oder mehr der Elektronikbauteile miteinander elektrisch kontaktiert sind. Auf diese Weise können sehr kurze Leitungsverbindungen von Elektronikbauteilen miteinander realisiert werden. Insbesondere zueinander schräg orientierte Flachseiten der Elektronikbauteile lassen sich mit solchen Durchkontaktierungen auf möglichst direktem und kurzem Wege, d.h. insbesondere auf geradem Wege, miteinander verbinden. In the case of the electronic module according to the invention, the circuit carrier preferably has plated-through holes which extend through the circuit carrier and by means of which at least two or more of the electronic components are electrically contacted with one another. In this way, very short wire connections of electronic components can be realized with each other. In particular obliquely oriented flat sides of the electronic components can be achieved with such plated-through holes as directly as possible and short distances, i. especially in a straight path, connecting with each other.
Alternativ oder zusätzlich kann das erfindungsgemäße Elektronikmodul Leiterbahnen aufweisen, welche entlang der Oberfläche des Schaltungsträgers verlaufen. Alternatively or additionally, the electronic module according to the invention may comprise conductor tracks which extend along the surface of the circuit carrier.
In einer vorteilhaften Weiterbildung der Erfindung ist das Elektronikmodul zumindest zum Teil additiv gefertigt und insbesondere mit einem 3D-Druckteil gebildet oder das Elektronikmodul ist ein 3D-Druckteil. In an advantageous development of the invention, the electronic module is at least partially made additive and in particular formed with a 3D printing part or the electronic module is a 3D printing part.
Besonders bevorzugt weisen bei dem erfindungsgemäßen Elektronikmodul die zumindest zwei Elektronikbauteile Sensoren, insbesondere Bewegungs- und/oder Kraftsensoren, auf. Gerade bei Sensoren ist es vorteilhaft, dass die Elektronikbauteile beliebig orientiert vom Schaltungsträger tragbar sind. Bei Sensoren ermöglicht diese Anordnung eine Erfassung aller drei Raumachsen. Eine solche Anordnung ist insbesondere im Falle von Bewegungssensoren und/oder Kraftsensoren von Vorteil. In the electronic module according to the invention, the at least two electronic components particularly preferably have sensors, in particular motion and / or force sensors. Especially with sensors, it is advantageous that the electronic components are arbitrarily oriented from the circuit board portable. For sensors, this arrangement allows detection of all three spatial axes. Such an arrangement is particularly advantageous in the case of motion sensors and / or force sensors.
Bei dem erfindungsgemäßen Verfahren zur Herstellung eines erfindungsgemäßen Elektronikmoduls wird zunächst der Schaltungsträger herangezogen und nachfolgend wird oder werden zumindest eine oder mehrere Durchkontaktierung/en in den Schaltungsträger eingebracht oder es wird zunächst eine Leiterbahnanordnung herangezogen, und nachfolgend wird der Schaltungsträger an die Leiterbahnanordnung angeordnet. Beispielsweise kann der Schaltungsträger zunächst als Spritzgussteil bereitgestellt werden, wonach in das Spritzgussteil Durchkontaktierungen eingebracht werden. Alternativ oder zusätzlich kann eine Leiterbahnanordnung gegeben sein, an welche der Schaltungsträger angeordnet wird, etwa als Spritzgussteil angespritzt wird. So können beispielsweise die Leiterbahnen frei tragend, beispielsweise durch das Formen von Drähten oder durch 3D-Druckverfahren, gefertigt werden und anschließend mit Kunststoff umspritzt werden. Grundsätzlich kann die Leiterbahnanordnung auch mit einem Opfermaterial gebildet sein, welches nach Umspritzung mit Kunststoff herausgelöst und/oder herausgeätzt und/oder thermisch entfernt wird. Auf diese Weise sind im Spritzgussteil Hohlräume gebildet, welche mittels Metallisierung metallisch gefüllt werden können. In the method according to the invention for producing an electronic module according to the invention, first of all the circuit carrier is used and subsequently at least one or more plated-through holes are inserted into the circuit carrier or a printed conductor arrangement is first used, and subsequently the circuit carrier is arranged on the printed conductor arrangement. For example, the circuit carrier may first be provided as an injection molded part, after which vias are introduced into the injection molded part. Alternatively or additionally, a conductor track arrangement may be provided, to which the circuit carrier is arranged, for example, is injection-molded as an injection molded part. Thus, for example, the tracks can be made freely, for example, by the forming of wires or by 3D printing process, and then encapsulated in plastic. In principle, the conductor track arrangement can also be formed with a sacrificial material which, after encapsulation with plastic, is dissolved out and / or etched out and / or thermally removed. In this way, cavities are formed in the injection molded part, which can be filled metallically by metallization.
Alternativ wird/werden in einem weiteren erfindungsgemäßen Verfahren zur Herstellung eines erfindungsgemäßen Elektronikmoduls zumindest der Schaltungsträger, vorzugsweise wird/werden zudem die ggf. vorhandene/n Durchkontaktierung/en des Elektronikmoduls, additiv gefertigt, insbesondere mittels 3D-Druckens gebildet. Auf diese Weise lässt sich das erfindungsgemäße Elektronikmodul in einem einzigen oder zumindest in möglichst wenigen Prozessschritten fertigen. Alternatively, in a further inventive method for producing an electronic module according to the invention, at least the circuit carrier is / are preferably / additionally also the optionally present via (s) of the electronic module produced additively, in particular by means of 3D printing. In this way, the electronic module according to the invention can be manufactured in a single or at least as few process steps as possible.
In einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens werden die Durchkontaktierungen mittels Laserbohrens und/oder Mikrobohrens und/oder mittels Ätzens gebildet. In a preferred embodiment of the method according to the invention, the plated-through holes are formed by means of laser drilling and / or micro-drilling and / or by etching.
Insbesondere wird/werden die Durchkontaktierung/en mittels Kanälen gebildet, welche in den Schaltungsträger eingebracht wird/werden. Um solche Durchführungen oder Kanäle zur elektrischen Leitung auszubilden, wird/werden diese Durchkontaktierung/en mittels Metallisierens und/oder mittels eines Liquid-Fill-Prozesses und/oder mittels galvanischen Metallabscheidens und/oder mittels elektrochemischen Metallabscheidens und/oder mittels Dispensens von flüssiger/n leitfähiger/n Paste/n gebildet. In particular, the via (s) is / are formed by channels which are / are incorporated into the circuit carrier. To form such feedthroughs or channels for electrical conduction, this via (s) is / are made by metallizing and / or by means of a liquid-fill process and / or by means of galvanic metal deposition and / or by means of electrochemical metal deposition and / or by dispensing of liquid / s conductive paste / s formed.
Geeigneter Weise wird/werden bei dem erfindungsgemäßen Verfahren die Durchkontaktierung/en mit Kontaktflächen versehen, insbesondere mittels fototechnischer Strukturierung und anschließender Metallisierung und/oder Dispensens leitfähigen/r Kleber/s und/oder Lotpaste/n. Suitably, in the method according to the invention, the via / s are provided with contact surfaces, in particular by means of phototechnical structuring and subsequent metallization and / or dispensing of conductive adhesive (s) and / or solder paste (s).
Vorzugsweise werden bei dem erfindungsgemäßen Verfahren die zumindest zwei Elektronikbauteile mittels Klebens und/oder Lötens und/oder Reibschweißens mit dem Schaltungsträger, insbesondere mittels der Kontaktflächen wie in der Weiterbildung zuvor beschrieben, angebunden. Diese Verfahren sind bereits für herkömmliche zweidimensionale Schaltungsträger bekannt und etabliert, sodass diese bekannten Prozesse auch zur Fertigung des erfindungsgemäßen Leistungsmoduls genutzt werden können. Preferably, in the method according to the invention, the at least two electronic components are connected to the circuit carrier by means of gluing and / or soldering and / or friction welding, in particular by means of the contact surfaces as described above. These methods are already known and established for conventional two-dimensional circuit carriers, so that these known processes can also be used to manufacture the power module according to the invention.
Bevorzugt werden bei dem erfindungsgemäßen Verfahren mehrere Elektronikmodule als einstückiger Zusammenhang gebildet und nachfolgend vereinzelt. Auf diese Weise kann bei der Fertigung auf einfache Weise eine hohe Stückzahl erreicht werden. In the method according to the invention, a plurality of electronic modules are preferably formed as one-piece connection and subsequently singulated. In this way, a high number of pieces can be achieved in a simple manner during production.
