Abstract
Description
Die Erfindung betrifft eine Leiterplatte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a printed circuit board according to the generic term of claim 1.
Leiterplatten sind als elektrische oder elektronische Komponenten für z.B. Steuerungen bekannt und werden unter anderem in Kraftfahrzeugen eingesetzt.Printed circuit boards are considered electrical or electronic components for e.g. Controls are known and used, among other things, in motor vehicles.
Aus der
Aufgabe der Erfindung ist es, eine Leiterplatte zu schaffen, bei der die Wärme von einem Leistungsbauteil, z.B. einem Halbleiter oder einem Widerstand, ungehindert zu einer Wärmesenke abgeleitet wird.The object of the invention is a To create a circuit board in which the heat from a power component, e.g. a semiconductor or a resistor, unhindered to one heat sink is derived.
Die Aufgabe ist durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Dadurch, dass die Leiterbahnen unmittelbar mit der Durchkontaktierung verbunden sind und dass die untere Leiterbahn durch eine elektrische Isolierung getrennt ist, wird die vom Leistungsbauteil erzeugte Wärme direkt in die Durchkontaktierung und weiter in die untere Leiterbahn geleitet. Die Wärmeableitung erfolgt also nur durch Metalle, die eine bessere Wärmeleitung aufweisen als die bei Leiterplatten eingesetzten elektrisch isolierenden Werkstoffe.The task is due to the characteristic features of claim 1 solved. The fact that the conductor tracks are connected directly to the plated-through hole are and that the lower trace by electrical insulation is separated, the heat generated by the power component is direct routed into the via and further into the lower conductor track. The heat dissipation is only done by metals that have better heat conduction have as the electrically insulating used in printed circuit boards Materials.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung.The subclaims relate to the advantageous embodiment the invention.
Wenn wie nach Anspruch 2 die elektrische Isolierung auf oder kurz beabstandet zu einer Mittelachse der unteren Leiterbahn verläuft, erfolgt die Wärmeableitung weitgehend symmetrisch und somit gleichmäßig.If as according to claim 2, the electrical insulation on or a short distance from a central axis of the lower conductor track runs, the heat is dissipated largely symmetrical and therefore even.
Die Füllung der Durchkontaktierung mit Lötzinn nach Anspruch 3 bewirkt einen höheren Wärmefluss durch die Durchkontaktierung.The filling of the via with solder according to claim 3 causes a higher heat flow through the via.
Die Erfindung wird anhand des in der Zeichnung vereinfacht dargestellten Ausführungsbeispiels näher erläutert. Es zeigenThe invention is based on the in the drawing, illustrated in simplified form, the embodiment. It demonstrate
