Description
Die vorliegende Erfindung betrifft einen elektronischen Schaltungsträger gemäß Oberbegriff von Anspruch 1, ein Verfahren gemäß Oberbegriff von Anspruch 5 und eine Verwendung des Schaltungsträgers gemäß Anspruch 6.The present invention relates to an electronic circuit carrier according to the preamble of claim 1, a method according to the preamble of
Elektrische Bauelemente können im Betrieb eine erhebliche Verlustwärme freisetzen, weshalb diese gekühlt werden müssen. Um diese Verlustwärme abzuführen ist es bekannt, mit den elektrischen Bauelementen thermisch gekoppelte Kühlkörper vorzusehen. In der
Aufgrund der hohen Stückzahlen, mit welchen Schaltungsträger produziert werden, besteht ein enormer Kostendruck auf sämtliche Komponenten. Insbesondere das Einsparen von Material sowie Prozessschritten bei der Herstellung sind hierbei preistreibende Faktoren. Des Weiteren besteht die Notwendigkeit das Gewicht bereits existierender Systeme weiter zu verringern, ohne deren Funktionalität einzuschränken. Due to the high quantities with which circuit carriers are produced, there is an enormous cost pressure on all components. In particular, the saving of material and process steps in the production are price-driving factors. Furthermore, there is a need to further reduce the weight of existing systems without restricting their functionality.
Aufgabe der Erfindung ist es daher, einen Schaltungsträger bereitzustellen, welcher preisgünstiger in der Herstellung ist sowie eine Gewichtseinsparung und eine verbesserte Qualitätskontrolle ermöglicht. The object of the invention is therefore to provide a circuit substrate, which is cheaper to manufacture and allows weight savings and improved quality control.
Diese Aufgabe wird durch einen Schaltungsträger gemäß Anspruch 1 und ein Verfahren gemäß Anspruch 5 gelöst.This object is achieved by a circuit carrier according to claim 1 and a method according to
Die Erfindung beschreibt einen Schaltungsträger, welcher eine Platine, elektronische Bauelemente und einen Kühlkörper umfasst, wobei der Kühlkörper mittels einer Lötverbindung mit der Platine und/oder wenigstens einem der elektronischen Bauelemente verbunden ist und einen Grundkörper aus Aluminium oder einer Aluminiumlegierung aufweist, wobei der Kühlkörper zur Verbesserung von dessen Lötbarkeit eine Nickelbeschichtung aufweist.The invention relates to a circuit carrier, which comprises a circuit board, electronic components and a heat sink, wherein the heat sink is connected by means of a solder connection to the circuit board and / or at least one of the electronic components and a base body made of aluminum or an aluminum alloy, wherein the heat sink for Improvement of its solderability has a nickel coating.
In vorteilhafter Weise besteht durch den erfindungsgemäßen Schaltungsträger ein wesentlicher Kostenvorteil beispielsweise gegenüber einem Schaltungsträger mit einem Kühlkörpers gleicher Abmessungen, welcher aus Kupfer gefertigt ist. Aufgrund der im Vergleich zu Kupfer geringeren Dichte von Aluminium ergeben sich für gleiche Abmessungen des Kühlkörpers des Weiteren wesentliche Gewichtseinsparungen, welche etwa 70 % betragen können.Advantageously, by the circuit carrier according to the invention a significant cost advantage, for example, compared to a circuit substrate with a heat sink of the same dimensions, which is made of copper. Further, due to the lower density of aluminum compared to copper, the same dimensions of the heat sink result in significant weight savings, which may be about 70%.
Ein weiterer Vorteil ergibt sich durch die Möglichkeit einer verbesserten Qualitätskontrolle der Lötstellen. Der gegenüber Röntgenstrahlung geringere Absorptionskoeffizient von Aluminium resultiert in einer verbesserten Auswertbarkeit der Lötstelle, da diese durch das Aluminium des Kühlkörpers weniger abgeschattet wird, als das für Kupfer der Fall ist. Somit können Lötlunker bei Durchführung einer Röntgenprüfung besser erkannt werden. Zusätzlich kann der inspizierte Lötbereich in vorteilhafter Weise im Wesentlichen uneingeschränkt im Bereich der vollständigen Platinenbohrung bzw. des vollständigen Lötdurchmessers erfolgen. Another advantage results from the possibility of improved quality control of the solder joints. The lower absorption coefficient of aluminum compared to X-ray radiation results in an improved evaluability of the solder joint, since it is less shaded by the aluminum of the heat sink than is the case for copper. Thus, solder holes can be better detected by performing an X-ray inspection. In addition, the inspected soldering area can be advantageously carried out substantially without restriction in the area of the complete board bore or of the complete soldering diameter.
Im Vergleich dazu erzeugt ein aus Kupfer bestehender Kühlkörper einen schwarzen, nicht inspizierbaren Schatten, welcher eine automatisierte Auswertung der Lötanbindung in diesem Bereich nicht zulässt.In comparison, an existing heat sink made of copper creates a black, unobservable shadow, which does not allow an automated evaluation of the solder connection in this area.
Weiterhin kann die Erfindung ohne Wesentliche Anpassungen, beispielsweise der Abmessungen eines Kühlkörpers, vorhandener Fertigungswerkzeuge und/oder einer Elektronik bzw. eines Schaltungsträgerlayouts realisiert werden, wodurch eine preisgünstige und zeitsparende Umsetzung möglich ist.Furthermore, the invention can be realized without significant adjustments, for example, the dimensions of a heat sink, existing manufacturing tools and / or electronics or a circuit carrier layout, whereby a low-cost and time-saving implementation is possible.
Gemäß einer besonders bevorzugten Ausführungsform beinhaltet die Nickelbeschichtung zusätzlich Phosphor. Zur weiteren Verbesserung der Löteigenschaften kann eine weitere Beschichtung bzw. Modifikation der Nickelbeschichtung insbesondere unter Verwendung von Palladium vorgesehen sein. Alternativ ist bevorzugt eine Beschichtung von Zinn oder einer Zinnlegierung auf der Nickelbeschichtung vorgesehen. According to a particularly preferred embodiment, the nickel coating additionally contains phosphorus. To further improve the soldering properties, a further coating or modification of the nickel coating can be provided, in particular using palladium. Alternatively, a coating of tin or a tin alloy on the nickel coating is preferably provided.
Die Nickelbeschichtung weist bevorzugt Phosphor mit einem Anteil im Bereich zwischen etwa 5 bis etwa 9 Gew.% auf. Somit werden besonders vorteilhafte Eigenschaften in Bezug auf die Lötfähigkeit der Oberfläche der Nickelbeschichtung ermöglicht. The nickel coating preferably comprises phosphorus at a level in the range of from about 5 to about 9 weight percent. Thus, particularly advantageous properties with respect to the solderability of the surface of the nickel coating are made possible.
Bevorzugt ist der Kühlkörper vollständig oder lediglich teilweise beschichtet, wobei die Beschichtung insbesondere für einen für die Lötverbindung vorgesehenen Teil des Kühlkörpers vorgesehen ist. In vorteilhafter Weise kann somit Beschichtungsmaterial eingespart werden. Preferably, the heat sink is completely or only partially coated, wherein the coating is provided in particular for a provided for the solder joint portion of the heat sink. Advantageously, coating material can thus be saved.
Bevorzugt weist die Nickelbeschichtung eine Dicke im Bereich von etwa 4 bis etwa 6 μm auf. Dies ermöglicht in vorteilhafter Weise einen ökonomischen Einsatz von Beschichtungsmaterial unter Berücksichtigung der notwendigen Qualität der Lötverbindung. Preferably, the nickel coating has a thickness in the range of about 4 to about 6 microns. This advantageously allows an economical use of coating material below Consideration of the necessary quality of the solder joint.
Die Erfindung beschreibt weiterhin ein Verfahren zur Fertigung eines Schaltungsträgers, welcher eine Platine, elektronische Bauelemente und einen Kühlkörper umfasst, wobei der Kühlkörper einen Grundkörper aufweist, welcher aus Aluminium oder einer Aluminiumlegierung besteht und mit der Platine und/oder wenigstens einem der elektronischen Bauelemente mittels einer Lötverbindung verbunden wird und zur Verbesserung von dessen dass der Kühlkörper (
Bevorzugt wird Nickelbeschichtung in einem Prozessschritt aufgebracht, welcher zumindest einem Trenn- und/oder Verformungsprozess zur Herstellung des Grundkörpers des Kühlkörpers folgt. Ein Vorteil davon ist, dass ein Ausdünnen bzw. Schädigen der Beschichtung in Folge des oder der Trenn- und/oder Verformungsprozesse vermieden und somit eine verbesserte Beschichtungs- bzw. Lötqualität erreicht wird. Die Nickelbeschichtung wird bevorzugt chemisch auf den Aluminium-Grundkörper aufgebracht, wobei alternative Beschichtungsverfahren, wie z.B. elektrolytische oder autokatalytische Abscheidung, ebenfalls angewendet werden können.Nickel coating is preferably applied in a process step which follows at least one separation and / or deformation process for producing the main body of the heat sink. One advantage of this is that thinning or damaging of the coating as a consequence of the or the separation and / or deformation processes is avoided and thus an improved coating or soldering quality is achieved. The nickel coating is preferably applied chemically to the aluminum body, alternative coating methods such as e.g. electrolytic or autocatalytic deposition, can also be applied.
Die Erfindung bezieht sich zudem auf die Verwendung des erfindungsgemäßen Schaltungsträgers in einem Kraftfahrzeugsteuergerät, insbesondere in einem Steuergerät eines Kraftfahrzeugbremssystems. The invention also relates to the use of the circuit substrate according to the invention in a motor vehicle control unit, in particular in a control unit of a motor vehicle brake system.
Weitere bevorzugte Ausführungsformen ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen an Hand von Figuren.Further preferred embodiments will become apparent from the following description of exemplary embodiments with reference to figures.
