Description
Stand der TechnikState of the art
Die Erfindung betrifft ein Verfahren zur Herstellung einer Leiterbildstruktur auf einem mit Metall beschichteten Substrat und ein mittels des Verfahrens hergestelltes Bauteil.The invention relates to a method for producing a patterned circuit pattern on a metal-coated substrate and a component produced by the method.
Aus der
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren zur Herstellung einer Leiterbildstruktur mit den Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil, dass sowohl sehr feine und dünne Leiterbildstrukturen als auch hoch leitfähige, insbesondere dicke, Leiterbildstrukturen hergestellt werden können.The inventive method for producing a patterned conductor structure with the features of the independent claim has the advantage that both very fine and thin pattern structures as well as highly conductive, in particular thick, pattern structures can be produced.
Besonders vorteilhaft ist, dass als Strahldruckverfahren ein Inkjet-Verfahren und/oder ein Aerosol-Jet-Verfahren verwendet werden, da diese Verfahren dazu beitragen, feine Leiterbildstrukturen zu erzeugen.It is particularly advantageous that an inkjet method and / or an aerosol-jet method are used as the jet printing method, since these methods contribute to producing fine conductor pattern structures.
Vorteilhaft ist ferner, dass das Metall Kupfer und/oder Zinn und/oder Silber und/oder Gold ist, da diese Metalle elektrisch leitfähig sind und zudem mit einem Plasmaauftragsverfahren auf ein Substrat aufgetragen werden können. Ferner ist ein flächiger Auftrag mittels eines Galvanikprozess bei metallisierbaren Kunststoffen, beispielsweise Acrylnitril-Butadien-Styrol (ABS), vorteilhaft.It is also advantageous that the metal is copper and / or tin and / or silver and / or gold, since these metals are electrically conductive and can also be applied to a substrate by a plasma deposition process. Furthermore, a flat application by means of a galvanic process with metallizable plastics, for example acrylonitrile-butadiene-styrene (ABS), is advantageous.
Besonders vorteilhaft ist, dass das Substrat ein Kunststoffsubstrat und/oder ein mineralisches Substrat und/oder ein organisches Substrat und/oder ein metallisches Substrat ist, da diese Substrate elektrisch isolieren und damit nach dem Ätzprozess als elektrisch isolierende Isolationsbereiche vorhanden sind.It is particularly advantageous that the substrate is a plastic substrate and / or a mineral substrate and / or an organic substrate and / or a metallic substrate, since these substrates are electrically insulated and thus present after the etching process as electrically insulating isolation regions.
Vorteilhaft ist ferner, dass das Substrat ein räumlich spritzgegossener Schaltungsträger ist, da ein solcher Schaltungsträger in vielen Anwendungsbereichen, wie bei Getriebesteuerungen, Sensoriken oder der Hochleistungselektronik, neue Gestaltungsmöglichkeiten und damit die Möglichkeit einer Miniaturisierung ermöglicht. Weitere Anwendungsmöglichkeiten des Herstellungsverfahrens sind die Kontaktierung von eingebetteten Bauteilen, sowie die Herstellung von Drucksensoren.A further advantage is that the substrate is a spatially injection-molded circuit carrier, since such a circuit carrier in many applications, such as in transmission controls, sensors or high-performance electronics, new design options and thus the possibility of miniaturization. Other possible applications of the manufacturing process are the contacting of embedded components, as well as the production of pressure sensors.
Besonders vorteilhaft ist ferner, dass die durch das Verfahren erzeugten Leiterbahnen der Leiterbildstruktur eine Breite zwischen 5µm und 10µm aufweisen und/oder dass die Abstände zwischen den erzeugten Leiterbahnen der Leiterbildstruktur zwischen 10µm und 20µm betragen, da dies die Herstellung von sehr feinen und eng beieinanderliegenden Leiterbahnen ermöglicht, so dass sehr kompakte Bauformen erhalten werden.It is also particularly advantageous that the printed circuit traces of the patterned pattern structure produced by the method have a width between 5 .mu.m and 10 .mu.m and / or that the distances between the produced printed conductors of the patterned pattern structure are between 10 .mu.m and 20 .mu.m, since this is the production of very fine and closely spaced interconnects allows so that very compact designs are obtained.
Vorteilhaft ist ferner, dass das Metall auf dem Substrat eine Schichtdicke von größer 50 µm, vorzugsweise von größer 100 µm, besonders bevorzugt von größer 200 µm aufweist, da hierdurch Leiterbahnen erstellbar sind, die einerseits durch die geringen Abstände dicht gepackt sind, aber gleichzeitig hohe Leistungen übertragen können. Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen mit Bezug zu den Figuren und aus den abhängigen Ansprüchen.A further advantage is that the metal has a layer thickness of greater than 50 .mu.m, preferably greater than 100 .mu.m, more preferably greater than 200 microns on the substrate, as this conductor tracks can be created, which are densely packed on the one hand by the small distances, but at the same time high Can transfer services. Further advantages will become apparent from the following description of embodiments with reference to the figures and from the dependent claims.
