Description
Die Erfindung betrifft ein Verfahren zum Verlöten von Bauteilen in SMD-Technik, wobei die Anschlusskontakte des Bauteils auf der Oberseite einer Leiterplatte verlötet werden sowie eine Leiterplatte mit wenigstens einem Bauteil in SMD-Technik, dessen Anschlusskontakte auf der Oberseite der Leiterplatte verlötet sind.The The invention relates to a method for soldering components in SMD technology, wherein the terminal contacts of the component on the top of a circuit board soldered be as well as a printed circuit board with at least one component in SMD technology, its connection contacts soldered to the top of the circuit board.
Bei der Verarbeitung von nicht-reflow-fähigen SMD-Bauteilen, die im Betrieb eine vergleichsweise hohe Verlustwärme produzieren, werden üblicherweise Spezialleiterplatten aus Aluminium verwendet, wobei die Bauteile mit einem aufwendigen Lötverfahren (Bügellöten) verarbeitet werden müssen, damit zu hohe Temperaturen beim Lötvorgang vermieden werden, die zu einer Beschädigung des Bauteils führen könnten.at the processing of non-reflowable SMD components used in the Operation produce a comparatively high heat loss, are usually Special PCBs used in aluminum, with the components with a complicated soldering process (Ironing) processed Need to become, so that too high temperatures are avoided during the soldering process, the damage lead the component could.
Der Erfindung liegt nun die Aufgabe zugrunde eine Leiterplatte mit wenigstens einem Bauteil in SMD-Technik sowie ein Verfahren zum Verlöten von Bauteilen in SMD-Technik anzugeben, sodass die Herstellungskosten reduziert werden können.Of the Invention is now the object of a printed circuit board with at least a component in SMD technology and a method for soldering components in SMD technology, thus reducing manufacturing costs can be.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 3 gelöst.According to the invention this Problem solved by the features of claims 1 and 3.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Ansprüche.Further Embodiments of the invention are subject of the claims.
Beim erfindungsgemäßen Verfahren zum Verlöten von Bauteilen in SMD-Technik werden die Anschlusskontakte des Bauteils auf der Oberseite einer Leiterplatte dadurch verlötet, dass die Leiterplatte im Bereich der Anschlusskontakte mit Durchgangsbohrungen versehen ist und die Verlötung der Anschlusskontakte von der Unterseite der Leiterplatte durch die Bohrungen erfolgt.At the inventive method for soldering of components in SMD technology become the connection contacts of the component soldered on top of a printed circuit board by that the printed circuit board in the area of the connection contacts with through holes is provided and the soldering the connection contacts from the bottom of the circuit board through the holes are made.
Die erfindungsgemäße Leiterplatte weist wenigstens ein Bauteil in SMD-Technik auf, wobei dessen Anschlusskontakte auf der Oberseite der Leiterplatte verlötet sind und die Leiterplatte zur Zuführung des Lots von der Unterseite der Leiterplatte im Bereich der Anschlusskontakte mit Durchgangsbohrungen versehen ist.The inventive circuit board has at least one component in SMD technology, wherein its connection contacts soldered to the top of the circuit board and the circuit board for feeding the Lots from the bottom of the PCB in the area of the connection contacts is provided with through holes.
Auf diese Weise wird das Lot von der Unterseite der Leiterplatte durch die Durchgangsbohrungen zugeführt, so dass eine unnötige und das Bauteil gegebenenfalls zerstörende Wärmezufuhr an das Bauteil vermieden wird.On this way, the solder from the bottom of the circuit board through supplied through holes, making an unnecessary and the component optionally destructive heat supply to the component avoided becomes.
Gemäß einer bevorzugten Ausführungsform erfolgt die Verlötung mit Hilfe eines Wellenlötverfahrens.According to one preferred embodiment takes place the soldering using a wave soldering process.
Gemäß einer weiteren Ausgestaltung der Erfindung ist die Leiterplatte im Bereich des Bauteils mit einer Vielzahl von Durchkontaktierungen zur Ableitung der Wärme versehen. Durch diese Maßnahme ist es möglich, herkömmliches Leiterplattenmaterial, beispielsweise aus dem Basismaterial FR4, zu verwenden, welches aus Epoxydharz getränkten Glasfasern besteht, wobei lediglich die Ober- und Unterseiten mit Kupfer kaschiert sind. Dieses Leiterplattenmaterial ist erheblich günstiger als die ansonsten für derartige Bauteile verwendeten Leiterplatten aus Metallsubstraten. Die Gesamtkosten der Leiterplatte können daher sowohl durch ein günstiges Leiterplattenmaterial als auch ein einfacheres Lötverfahren reduziert werden.According to one Another embodiment of the invention, the circuit board in the area of the component with a plurality of vias for dissipation the heat Mistake. By this measure is it is possible conventional Printed circuit board material, for example from the base material FR4, to use, which consists of epoxy resin impregnated glass fibers, wherein only the upper and Lower sides are laminated with copper. This circuit board material is considerably cheaper as the otherwise for such Components used printed circuit boards made of metal substrates. The total cost the circuit board can therefore both by a favorable PCB material as well as a simpler soldering process can be reduced.
Weitere Ausgestaltungen und Vorteile der Erfindung werden im folgenden anhand der Beschreibung eines Ausführungsbeispieles und der Zeichnung näher erläutert.Further Embodiments and advantages of the invention will be described below the description of an embodiment and the drawing closer explained.
