Die Erfindung betrifft einen Bauteileverbund sowie ein Verfahren zum Herstellen eines Bauteileverbunds nach den Oberbegriffen der beiden unabhängigen Ansprüche. Ferner betrifft die Erfindung die Verwendung eines erfindungsgemäßen Verfahrens zur Herstellung eines Bauteileverbunds. The invention relates to a composite component and a method for producing a composite component according to the preambles of the two independent claims. Furthermore, the invention relates to the use of a method according to the invention for producing a component composite.
Ein Bauteileverbund bzw. ein Verfahren zum Herstellen eines Bauteileverbunds nach dem Oberbegriff der beiden unabhängigen Ansprüche ist aus der
Bei der Herstellung von Elektronikbaugruppen werden oftmals Schaltungsträger, zum Beispiel in Form von Leiterplatten, Kupfer- oder Keramiksubstraten verwendet, auf denen elektronische (Schaltungs-)Bauteile mittels eines Lötverfahrens befestigt werden. Die so ausgebildete Einheit wird anschließend zum Schutz gegen Medien teilweise umspritzt, wozu aushärtbare Kunststoffe verwendet werden. Wenn man nun das erste Bauteil (Schaltungsträger) mit der oben erwähnten Oberflächenstruktur versieht, so kommt es bei dem Lotprozess dazu, dass beispielsweise Flussmittel oder Lot auf den Bereich der Oberflächenstruktur des ersten Bauteils gelangt und die Oberflächenstruktur ausfüllt bzw. zusetzt. Dadurch ist der Zweck der Oberflächenstruktur, die verbesserte Haftung und Dichtigkeit zwischen dem ersten Bauteil und dem Material des zweiten Bauteils (Umspritzung aus Kunststoff) zu ermöglichen, nicht mehr erreichbar. In the manufacture of electronic assemblies circuit substrates are often used, for example in the form of printed circuit boards, copper or ceramic substrates, on which electronic (circuit) components are attached by means of a soldering process. The unit formed in this way is then partially encapsulated for protection against media, for which purpose hardenable plastics are used. If the first component (circuit carrier) is provided with the above-mentioned surface structure, then the soldering process causes, for example, flux or solder to reach the region of the surface structure of the first component and fill or add the surface structure. As a result, the purpose of the surface structure, the improved adhesion and tightness between the first component and the material of the second component (plastic encapsulation) to enable, no longer achievable.
Offenbarung der ErfindungDisclosure of the invention
Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Bauteileverbund bzw. ein Verfahren zum Herstellen eines Bauteileverbunds nach den Oberbegriffen der beiden unabhängigen Ansprüche derart weiterzubilden, dass bei der Herstellung von Bauteileverbunden, bei denen ein Schaltungsbauteil über einen Lötprozess mit dem ersten Bauteil verbunden wird, verhindert wird, dass die beim Lötvorgang verwendeten Stoffe (insbesondere Flussmittel sowie Lot) in den Bereich der ersten Kontaktoberfläche, die mit der Oberflächenstruktur versehen ist, gelangt. Based on the illustrated prior art, the invention has the object, a composite component or a method for producing a component assembly according to the preambles of the two independent claims such that in the manufacture of component interconnections, in which a circuit component via a soldering process with the the first component is connected, prevents the substances used in the soldering process (in particular flux and solder) in the region of the first contact surface, which is provided with the surface structure passes.
Diese Aufgabe wird erfindungsgemäß bei einem Bauteileverbund mit den Merkmalen des Anspruchs 1 dadurch gelöst, dass das erste Bauteil eine zusätzliche Kontaktoberfläche aufweist, die dazu ausgebildet ist, mit einem Schaltungsbauteil mittels einer Lötverbindung verbunden zu werden, und dass zwischen der zusätzlichen Kontaktoberfläche und der ersten Kontaktoberfläche ein Barriereelement an dem ersten Bauteil angeordnet ist, das dazu ausgebildet ist, einen Übergang von beim Lötvorgang des Schaltungsbauteils verwendeten Stoffen von der zusätzlichen Kontaktoberfläche auf die erste Kontaktoberfläche zu verhindern.This object is achieved in a component assembly with the features of claim 1, characterized in that the first component has an additional contact surface, which is adapted to be connected to a circuit component by means of a solder connection, and that between the additional contact surface and the first contact surface a barrier element is arranged on the first component, which is designed to prevent a transition of substances used in the soldering process of the circuit component from the additional contact surface to the first contact surface.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Bauteileverbunds sowie des Verfahrens eines Bauteileverbunds sind in den jeweiligen Unteransprüchen aufgeführt. Advantageous developments of the component assembly according to the invention and the method of a component assembly are listed in the respective subclaims.
In besonders bevorzugter konstruktiver Ausgestaltung des Barriereelements ist es vorgesehen, dass das Barriereelement die zusätzliche Kontaktoberfläche vollständig umgibt. Dadurch wird ein Übertritt von beim Lötvorgang verwendeten Stoffen in alle Richtungen am ersten Bauteil sicher vermieden. In a particularly preferred structural embodiment of the barrier element, it is provided that the barrier element completely surrounds the additional contact surface. This reliably prevents the transfer of substances used in the soldering process in all directions on the first component.
Bevorzugt ist der Einsatz bei ersten Bauteilen, die zumindest im Bereich der zusätzlichen Kontaktoberfläche aus Kupfer bestehen oder als Leiterplatte bzw. Keramiksubstrat ausgebildet sind. Preferably, the use in the case of first components which consist of copper at least in the region of the additional contact surface or are formed as a printed circuit board or ceramic substrate.
In einer bevorzugten Ausgestaltung zur Erfüllung der Barrierefunktion wird vorgeschlagen, dass das Barriereelement in Form einer Oberflächenstrukturierung des ersten Bauteils ausgebildet ist, auf der die beim Lötvorgang des Schaltungsbauteils verwendeten Stoffe nicht oder nur wenig haften. In a preferred embodiment for the fulfillment of the barrier function, it is proposed that the barrier element is embodied in the form of a surface structuring of the first component on which the substances used during the soldering process of the circuit component do not adhere or adhere only slightly.
In alternativer Ausgestaltung kann es jedoch auch vorgesehen sein, dass das Barriereelement in Form einer Oberflächenstrukturierung des ersten Bauteils ausgebildet ist, die wenigstens eine Vertiefung, vorzugsweise in Form wenigstens eines länglichen Grabens aufweist. In an alternative embodiment, however, it may also be provided that the barrier element is designed in the form of a surface structuring of the first component, which has at least one recess, preferably in the form of at least one elongated trench.
Darüber hinaus kann es vorgesehen sein, dass nicht nur die erste Kontaktoberfläche, sondern auch die zusätzliche Kontaktoberfläche mit einer Oberflächenstruktur zur Erhöhung der Haftung der beim Lötvorgang verwendeten Stoffe aufweist. Dadurch wird der Vorteil erzielt, dass zum einen die Haftung des Lotmaterials auf der zusätzlichen Kontaktoberfläche verbessert wird, und zum anderen wird die Tendenz vermindert, dass auf der zusätzlichen Kontaktoberfläche befindliche Stoffe für den Lötvorgang außerhalb der zusätzlichen Kontaktoberfläche gelangen, da diese selbst besonders gut an der zusätzlichen Kontaktoberfläche anhaften bzw. dort gebunden werden. Moreover, it may be provided that not only the first contact surface, but also the additional contact surface with a surface structure to increase the adhesion of Having used in the soldering process substances. This has the advantage that on the one hand, the adhesion of the solder material is improved on the additional contact surface, and on the other hand, the tendency is reduced that located on the additional contact surface materials for the soldering outside the additional contact surface, as these themselves particularly good adhere to the additional contact surface or be bound there.
Bei einem erfindungsgemäßen Verfahren zum Herstellen eines Bauteileverbunds ist es in einer bevorzugten Ausgestaltung vorgesehen, dass das Barriereelement in Form wenigstens einer grabenförmigen Vertiefung ausgebildet wird, dass die wenigstens eine Vertiefung durch Abtragen von Material am ersten Bauteil gebildet wird, wobei der Materialabtrag vorzugsweise durch eine elektromagnetische Strahlungsquelle in Form einer Laserstrahleinrichtung, vorzugsweise eines Ultrakurzpulslasers erfolgt, dessen Laserstrahl zur Beeinflussung der Tiefe der Vertiefung durch die Repetitionsrate, die Pulsenergie, die Scangeschwindigkeit oder die Anzahl der Überfahrten eingestellt wird. In a method according to the invention for producing a component assembly, it is provided in a preferred embodiment that the barrier element is formed in the form of at least one trench-shaped recess, that the at least one recess is formed by removing material on the first component, wherein the material removal preferably by an electromagnetic Radiation source in the form of a laser beam device, preferably an ultrashort pulse laser, whose laser beam is adjusted to influence the depth of the depression by the repetition rate, the pulse energy, the scanning speed or the number of crossings.
Darüber hinaus ist es bei dem erfindungsgemäßen Verfahren insbesondere vorgesehen, dass nach dem Ausbilden des Barriereelements das erste Bauteil mit dem Schaltungsbauteil im Bereich der weiteren Kontaktoberfläche durch einen Lötvorgang verbunden wird, und dass zuletzt das erste Bauteil und das Schaltungsbauteil von dem aus Kunststoff bestehenden Materials des zweiten Bauteils zumindest bereichsweise umspritzt wird.
