Erfindungsgemäß werden Kontaktierungspasten bereitgestellt, die leicht zersetzbare Silberverbindungen aufweisen. Diese erfindungsgemäßen Pasten ermöglichen ein Kontaktieren bei niederem Anpressdruck, insbesondere unter 5 bar, vorzugsweise unter 3 bar und eine Prozesstemperatur von ca. 230°C, d. h. unter 250°C, insbesondere unter 240°C.Silver compounds, which is below 300 ° C, especially below 250 ° C. decompose and thereby form elemental silver, are particularly suitable sintered pastes significantly improve their application. According to the invention Contacting pastes provided the easily decomposable silver compounds exhibit. These pastes according to the invention enable a contact at low contact pressure, in particular under 5 bar, preferably below 3 bar and a process temperature of about 230 ° C, d. H. below 250 ° C, especially below 240 ° C.
Die erfindungsgemäße Kontaktierung zwischen den Oberflächen ist bei über 200°C temperaturwechselbeständig, und zwar über 2.000 Zyklen. Damit übertrifft die Kontaktierungspaste die mit Weichlotlegierungen oder Leitklebern erzielbare Temperaturbeständigkeit und Temperaturwechselbeständigkeit. Im Rahmen der vorliegenden Erfindung wird es somit ermöglicht, dass die Kontaktierungstemperatur der Kontaktierungspaste unter der Betriebstemperatur der mit der Paste hergestellten Kontakte liegt. Die erfindungsgemäß leicht zersetzlichen Silberverbindungen sind einfacher herstellbar und leichter zu konservieren als Nanosilber.The contacting according to the invention between the surfaces is temperature change resistant at over 200 ° C, over 2,000 cycles. This surpasses the Contact paste with soft solder alloys or conductive adhesives achievable temperature resistance and thermal shock resistance. In the context of the present invention, it is thus possible that the contacting temperature of the contacting paste under the operating temperature of the contacts made with the paste lies. The inventively easily decomposable silver compounds are easier to prepare and easier to preserve than nanosilver.
Maßgeblich ist, dass die Paste neben ihren organischen Bestandteilen wie Lösungsmittel und/oder Carbonsäuren eine leicht zersetzliche Silberverbindung aufweist, durch die eine Verarbeitung wie mit Weichlot unter 400°C ermöglicht wird. Vorzugsweise bildet die Silberverbindung unter 300°C, insbesondere unter 250°C, metallisches Silber. Geeignete Silberverbindungen sind Silberoxid, Silberkarbonat und insbesondere organische Silberverbindungen. Besonders bewährt hat sich Silberlaktat.decisive is that the paste in addition to its organic ingredients such as solvents and / or Carboxylic acids are an easily decomposable silver compound through which processing as with soft solder below 400 ° C is possible. Preferably, the silver compound forms below 300 ° C, especially below 250 ° C, metallic Silver. Suitable silver compounds are silver oxide, silver carbonate and in particular organic silver compounds. Especially proven has silver lactate.
Es wird vermutet, dass die erfindungsgemäßen Pasten und Verfahren auf der Bildung von hochreaktivem in situ erzeugtem Silber beruhen, das die Kontaktflächen und die gegebenenfalls in der Paste vorliegenden Feststoffe miteinander verbindet.It is believed that the pastes of the invention and methods for the formation of highly reactive in situ generated Silver are based on the contact surfaces and, where appropriate in the paste present solids together.
Leicht zersetzbare Silberverbindungen sind in bekannten Pasten, beispielsweise zusammen mit Silberflocken oder Nanosilber oder einer Kombination aus Silberflocken und Nanosilber anwendbar. In einer weiteren bevorzugten Ausführung wird eine Paste mit einer leicht zersetzlichen Silberverbindung und Kupferpulver bereitgestellt. Die Teilchengröße des Kupferpulvers beträgt vorzugsweise unter 10 μm.Light decomposable silver compounds are in known pastes, for example together with silver flakes or nanosilver or a combination made of silver flakes and nano silver applicable.
