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 DE 43 45 946 A1 ist eine Anordnung bestehend aus einer Leiterplatte mit mindestens einem Leistungsbauelement bekannt, das auf einer zugehörigen Lotfläche befestigt ist. Es ist mindestens eine Durchkontaktierung zur Wärmeableitung vom Leistungsbauelement zu einer Wärmesenke angeordnet, wobei die Durchkontaktierung außerhalb der Lotfläche ausgebildet ist. Zwischen dem Leistungsbauelement und der Wärmesenke besteht mindestens eine elektrisch isolierende Unterbrechung. Nachteil dieser Anordnung ist, dass das Material der elektrisch isolierenden Unterbrechung schlechter wärmeleitend ist als z.B. die Lotfläche. Daher wird der Wärmefluss zu der Durchkontaktierung behindert.From the DE 43 45 946 A1 an arrangement consisting of a printed circuit board with at least one power component is known, which is attached to an associated solder surface. At least one via for heat dissipation from the power component to a heat sink is arranged, the via being formed outside the solder surface. There is at least one electrically insulating interruption between the power component and the heat sink. The disadvantage of this arrangement is that the material of the electrically insulating interruption is less thermally conductive than, for example, the solder surface. Therefore, the heat flow to the via is blocked.

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

1 einen Teil einer Leiterplatte vergrößert senkrecht von oben und 2 einen Schnitt gemäß 1. 1 part of a circuit board enlarged vertically from above and 2 a cut according to 1 ,

Wie aus den Figuren ersichtlich besteht eine Leiterplatte 1 aus einer Platte 2 mit darauf befestigten Leiterbahnen 3, 3.1, 3.2 und mindestens einem Leistungsbauteil 4.As can be seen from the figures, there is a printed circuit board 1 from a plate 2 with conductor tracks attached to it 3 . 3.1 . 3.2 and at least one power component 4 ,

Die Platte 2 besteht wie bekannt aus isolierendem Material wie z.B. Keramik oder Kunststoff. In die Platte 2 sind entsprechend den Erfordernissen durchgehende, senkrecht zu den Hauptflächen verlaufende Bohrungen eingelassen.The plate 2 consists, as is known, of insulating material such as ceramic or plastic. In the plate 2 are drilled through, perpendicular to the main surfaces, according to the requirements.

Auf beiden Hauptflächen, das heißt auf den Oberflächen der Platte 2, die sich gegenüberliegen und am größten sind, sind die Leiterbahnen 3, 3.1, 3.2 aus z.B. Kupfer, die Kontaktflächen und/oder flächige Schichten wie die Leiterbahnen 3.1, 3.2 sowie bahnförmige Schichten wie die Leiterbahn 3 umfassen, unlösbar befestigt. Jede Leiterbahn 3, 3.1, 3.2 hat eine Dicke von ca. 20 – 400 μm.On both main surfaces, i.e. on the surfaces of the plate 2 that are opposite and largest are the traces 3 . 3.1 . 3.2 made of copper, for example, the contact surfaces and / or flat layers such as the conductor tracks 3.1 . 3.2 as well as sheet-like layers like the conductor track 3 include, permanently attached. Every trace 3 . 3.1 . 3.2 has a thickness of approx. 20 - 400 μm.

Auf zwei flächig ausgebildeten oberen Leiterbahnen 3.1 ist ein Leistungsbauteil 4, hier ein Widerstand, in SMD (Surface Mounted Device) – Technik, das heißt auf einer Oberfläche der Leiterplatte 1, befestigt. Auf der dem Leistungsbauteil 4 gegenüberliegenden Oberfläche der Platte 2 ist eine weitere flächig ausgebildete, untere Leiterbahn 3.2 angeordnet, die den oberen Leiterbahnen 3.1 genau gegenüberliegt. Jede Fläche dieser gegenüberliegenden Leiterbahnen 3.1, 3.2 ist größer als die mit der Leiterplatte 1 in Kontakt stehende Fläche des Leistungsbauteils 4.On two flat upper traces 3.1 is a power component 4 , here a resistor, in SMD (Surface Mounted Device) technology, that is, on a surface of the circuit board 1 , attached. On the power component 4 opposite surface of the plate 2 is another flat, lower conductor track 3.2 arranged that the upper conductor tracks 3.1 is exactly opposite. Any surface of these opposite traces 3.1 . 3.2 is larger than that with the circuit board 1 contact surface of the power component 4 ,

Die Leiterbahnen 3.1, 3.2 sind durch herkömmliche Durchkontaktierungen 5 in den entsprechenden Bohrungen elektrisch und thermisch leitend verbunden. Die Durchkontaktierungen 5 sind mit Lötzinn gefüllt.The conductor tracks 3.1 . 3.2 are through conventional vias 5 electrically and thermally conductively connected in the corresponding holes. The vias 5 are filled with solder.

Die untere Leiterbahn 3.2 ist durch eine elektrische Isolierung 6 getrennt. Diese verläuft längs einer Mittelachse der unteren Leiterbahn 3.2. Die Isolierung 6 ist in diesem Beispiel als Trennung der Leiterbahn 3.2, das heißt als ein länglicher schmaler Streifen ohne Material, ausgeführt und verhindert einen Kurzschluss zwischen unterschiedliche Potentiale führenden Leiterbahnen bzw. mit einer Wärmesenke.The lower trace 3.2 is through electrical insulation 6 Cut. This runs along a central axis of the lower conductor track 3.2 , The insulation 6 is in this example as a separation of the conductor track 3.2 , that is to say as an elongated narrow strip without material, and prevents a short circuit between conductor tracks carrying different potentials or with a heat sink.

In direktem Kontakt mit der unteren Leiterbahn 3.2 steht die nicht dargestellte Wärmesenke, die die Wärme sicher ableitet. Die Wärmesenke ist z.B. ein Teil eines Gehäuses.In direct contact with the lower trace 3.2 stands the heat sink, not shown, which safely dissipates the heat. The heat sink is part of a housing, for example.

Die Herstellung der Leiterplatte 1 erfolgt wie üblich für SMD- Leiterplatten mit dem Unterschied, dass die unteren Leiterbahnen 3.2 in zwei elektrisch voneinander isolierte Teile aufgeteilt werden. Die Durchkontaktierungen 5 werden durch z.B. Wellenlöten mit dem Lötzinn gefüllt.The manufacture of the circuit board 1 is done as usual for SMD circuit boards with the difference that the lower conductor tracks 3.2 be divided into two electrically insulated parts. The vias 5 are filled with solder, for example by wave soldering.

Im Betrieb erzeugt das Leistungsbauteil 4 Wärme. Diese wird über die oberen Leiterbahnen 3.1 durch die Durchkontaktierungen 5 in die untere Leiterbahn 3.2 abgeleitet und von hier von der Wärmesenke übernommen. Die Wärmesenke strahlt die Wärme z.B. in die Umgebung ab.The power component generates during operation 4 Warmth. This is over the top traces 3.1 through the vias 5 in the lower lei terbahn 3.2 derived and taken from here by the heat sink. The heat sink radiates heat, for example, into the environment.
