Abstract

The PCB is formed as a hybrid power circuit board and comprises all control and regulation functionalities. An aluminium base plate (2) is provided underneath the circuit board (1). Cooling-tower-shaped aluminium profiles (3) project vertically from the base plate, and penetrate the circuit board, and project out of its upper surface area (4). The aluminium profiles are thermally connected to power semiconductors (5) to provide a heat dissipation. A plastics layer (7) filled with ceramic material is provided in the gap (6) between the aluminium base plate and the circuit board, to permit direct heat dissipation from the circuit board and the components (9) assembled on the lower surface area (8) of the circuit board. The ceramic layer produces a proportionally high tensional stress on its upper and lower surfaces (11,12) simultaneously. Insolated high current areas (13) are provided on the under side of the board through the ceramic filled plastics layer.

Description

Die Erfindung betrifft eine Platine mit auf ihrer Lötseite montierten Bauelementen.The invention relates to a circuit board with on its solder side assembled components.

Der Einsatz von Schaltungsplatinen ist in der Elektro­ trotechnik, insbesondere in der Elektronik hinlänglich be­ kannt. Bedarf besteht jedoch hinsichtlich einer Platine als Netzteil für Hochstrom- , Hochspannungsapplikationen mit großer Leistung wie z. B. für Lasernetzteile, für Blitz­ technik und Reglertechnik, um Kabelanschlüsse und parasi­ täre Induktivitäten zu vermeiden, die EMV-Problematik ge­ ring zu halten, durch kompakte Bauweise den Platzbedarf zu reduzieren und für eine optimale Wärmeabfuhr über Luft- oder Wasserkühlung zu sorgen.The use of circuit boards is in electronics trotechnik, especially in electronics knows. However, there is a need for a circuit board as a power supply for high-current, high-voltage applications with great performance such. B. for laser power supplies, for flash technology and controller technology to make cable connections and parasi Avoid tary inductances, the EMC problem ring to keep the space required due to compact design reduce and for optimal heat dissipation via air or To provide water cooling.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Pla­ tine der eingangs genannten Art so zu gestalten, daß die zuvor genannten Anforderungen bei ihrer Anwendung für Hochstrom- , Hochspannungsapplikation mit großer Leistung erfüllt werden.The invention is therefore based on the object, a pla tine of the type mentioned in such a way that the aforementioned requirements in their application for  High current, high voltage application with great performance be fulfilled.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Platine als eine Hybrid-Power-Platine für Hochstrom- und/oder Hochspannungsapplikationen ausgelegt ist, die alle Kontroll- und Steuerfunktionalitäten aufweist, wobei un­ terhalb der Platine eine Aluminiumgrundplatte vorgesehen ist, aus der kühlturmartig Alu-Profile senkrecht heraus­ stehen, die die Platine durchsetzen und über deren obere Fläche hinausragen und an denen Leistungshalbleiter wärme­ kontaktiert sind, wobei eine den Zwischenraum zwischen der Aluminiumgrundplatte und der Platine ausfüllende,keramisch gefüllte Kunststoffschicht vorgesehen ist, durch die eine Wärmeableitung direkt aus der Platine gegenüber der Alumi­ niumgrundplatte und den auf der unteren Fläche der Platine montierten Bauelementen gegeben ist und deren Keramik­ schicht auf ihrer Ober- und Unterseite zugleich eine ver­ hältnismäßig hohe Spannungsfestigkeit der Platine bedingt, und wobei auf der unteren Fläche der Platine durch die ke­ ramisch gefüllte Kunststoffschicht isolierte Hochstrombe­ reiche vorgesehen sind.This object is achieved in that the Board as a hybrid power board for high current and / or High voltage applications is designed, all Control and control functionalities, wherein un an aluminum base plate is provided below the circuit board is from the cooling tower-like aluminum profiles vertically stand that penetrate the board and over the top Project surface and where power semiconductors heat are contacted, one of the spaces between the Aluminum base plate and the circuit board filling, ceramic filled plastic layer is provided through one Heat dissipation directly from the board opposite the aluminum nium base plate and on the lower surface of the board assembled components and their ceramics layer on its top and bottom at the same time relatively high dielectric strength of the board, and being on the lower surface of the board by the ke ramisch filled plastic layer insulated Hochstrombe rich are provided.

Vorzugsweise sind die Hochstrombereiche von Kupferstäben gebildet, die auf der unteren Fläche der Platine aufgelö­ tet und in der Keramikfüllmasse gelagert sind. Die Hoch­ strombereiche können auch von Kupferflächen gebildet sein, die galvanisch in Multilayer-Technik auf der unteren Flä­ che aufgebracht und in der isolierenden Keramikfüllmasse eingebettet sind.Preferably the high current areas are copper bars formed which resolved on the lower surface of the board tet and stored in the ceramic filling compound. The high current areas can also be formed by copper surfaces, the galvanic in multilayer technology on the lower surface che applied and in the insulating ceramic filling compound are embedded.

Die keramisch gefüllte Kunststoffschicht hat die Struktur einer hochgefüllten anorganischen Matrix und besteht vor­ zugsweise zu etwa 80% aus Keramikpartikeln.The ceramic-filled plastic layer has the structure a highly filled inorganic matrix and exists preferably about 80% ceramic particles.

Die Alu-Profile sind bevorzugt Vierkantprofile, die ca. 25 mm über die obere Fläche der Platine ragen können, wobei ihre freien Enden Kühlfahnen bilden.The aluminum profiles are preferably square profiles that are approx. 25  mm may protrude above the top surface of the board, with its free ends form cooling fins.

Da die Leistungshalbleiter an den kühlturmartigen Alu-Profi­ len wärmekontaktiert sind, ist über den verhältnismäßig gro­ ßen Querschnitt der jeweiligen Alu-Vierkantprofile eine opti­ male Kühlung gegenüber der Aluminiumgrundplatte möglich. Die erfindungsgemäße Hybrid-Power-Platine zeichnet sich durch ei­ ne kompakte Bauweise aus,wodurch ein geringer Platzbedarf ge­ geben ist. Da sich auf der Platine Kontroll- und Steuerfunk­ tionalitäten befinden, kann auf störanfällige und arbeitsin­ tensive Verkabelung verzichtet werden und parasitäre Indukti­ vitäten werden zugleich vermieden. Außerdem sorgt die Kera­ mikschicht auf der Ober- und Unterseite für eine hohe Span­ nungsfestigkeit der Platine, die deren Verwendung für Hoch­ strom- , Hochspannungsapplikation mit großer Leistung wie z. B. als Lasernetzteil, für die Blitztechnik und Reglertechnik bestens geeignet macht.Because the power semiconductors on the cooling tower-like aluminum professional len are in contact with heat is relatively large ß cross section of the respective aluminum square profiles an opti Male cooling possible compared to the aluminum base plate. The Hybrid power board according to the invention is characterized by egg ne compact design, resulting in a small footprint give is. Since there is control and control radio on the board functionalities, can be prone to malfunction and work tensive wiring and parasitic inductance vities are avoided at the same time. The Kera also ensures Mic layer on the top and bottom for a high chip resistance of the board, its use for high Current, high voltage application with great performance such as B. as a laser power supply, for flash technology and controller technology ideally suited.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Hybrid- Platine wird nun anhand der einzigen Figur der Zeichnung be­ schrieben, die eine Schnittansicht des Aufbaus dieser Ausfüh­ rungsform zeigt.A preferred embodiment of the hybrid Circuit board will now be based on the single figure of the drawing who wrote a sectional view of the construction of this embodiment form shows.

Wie die Figur verdeutlicht, sind auf der Lötseite bzw. un­ teren Fläche 8 der Platine 1 in herkömmlicher Weise Bauele­ mente 9 wie z. B. Leistungskondensatoren montiert. Unterhalb der Platine 1 ist im Abstand eine Aluminiumgrundplatte 2 vor­ gesehen, die auf dem Boden 16 eines die Hybrid-Platine auf­ nehmenden Gehäuses 17 gelagert ist. Aus der Aluminiumgrund­ platte 2 stehen bei der dargestellten Ausführungsform drei im Abstand zueinander angeordnete kühlturmartige Alu-Vier­ kantprofile 3 senkrecht heraus, durchsetzen die Platine 1 und ragen über die obere Fläche 4 der Platine 1 etwa 25 mm hinaus. An den freien oberen Enden 14 der kühlturmartigen Alu-Vier­ kantprofile 3 sind Leistungshalbleiter 5 wärmekontaktiert, so daß die von letzteren ab gegebene Wärme über die Kühlfahnen 14 der Alu-Vierkantprofile 3 zu deren unteren Enden 15 und damit zur Aluminiumgrundplatte 2 abgeführt werden kann. Der Zwischenraum 6 zwischen der Aluminiumgrundplatte 2 und der Platine 1 ist mit einer isolierenden keramisch gefüllten Kunststoffschicht 7 ausgefüllt, die zu etwa 80% aus Keramik­ partikeln besteht. Diese Keramikfüllmasse 7 ermöglicht die Wärmeableitung direkt aus der Platine 1 gegenüber der Alumi­ niumgrundplatte 2 und den auf der unteren Fläche 8 der Plati­ ne 1 montierten Bauelementen 9 und sorgt mit ihrer Keramik­ schicht auf der Ober- und Unterseite 11 bzw. 12 zugleich für eine hohe Spannungsfestigkeit der Platine 1, auf der sich al­ le Kontroll- und Steuerfunktionalitäten befinden. Weiterhin sind auf der unteren Fläche 8 der Platine 1 Hochstrombereiche 13 vorgesehen, die in Form von Kupferstäben in der isolieren­ den Keramikfüllmasse 7 eingebettet sind.As the figure shows, are on the solder side or un lower surface 8 of the circuit board 1 in a conventional manner, elements 9 such as. B. power capacitors mounted. Below the circuit board 1 , an aluminum base plate 2 is seen at a distance, which is mounted on the bottom 16 of a housing 17 which takes the hybrid circuit board. From the aluminum base plate 2 in the illustrated embodiment, three spaced-apart cooling tower-like aluminum square profiles 3 stand out vertically, penetrate the board 1 and protrude beyond the upper surface 4 of the board 1 by about 25 mm. At the free upper ends 14 of the cooling tower-like aluminum four-section profiles 3 , power semiconductors 5 are heat-contacted, so that the heat given off by the latter can be dissipated via the cooling vanes 14 of the aluminum square sections 3 to their lower ends 15 and thus to the aluminum base plate 2 . The space 6 between the aluminum base plate 2 and the circuit board 1 is filled with an insulating ceramic-filled plastic layer 7 , which consists of approximately 80% ceramic particles. This Keramikfüllmasse 7 allows the heat dissipation directly from the board 1 with respect to the Alumi niumgrundplatte 2 and on the lower surface 8 of the Plati ne 1 mounted components 9 and, with its ceramic layer on the top and bottom 11 and 12 respectively at the same time a high level of Dielectric strength of the circuit board 1 , on which all control and control functionalities are located. Furthermore, high current areas 13 are provided on the lower surface 8 of the circuit board 1 , which are embedded in the form of copper rods in the insulating ceramic filling compound 7 .

Bei der Herstellung der den Zwischenraum 6 ausfüllenden kera­ misch gefüllten Kunststoffschicht, die bei der dargestellten Ausführungsform der Hybrid-Platine etwa eine Stärke von 25 mm aufweist, werden in flüssigen Kunststoff Keramikpartikel un­ ter Bildung einer anorganischen Matrix mit 80% Keramikan­ teil eingefüllt In the manufacture of the space 6 filling the ceramic-filled plastic layer, which in the illustrated embodiment of the hybrid circuit board has a thickness of approximately 25 mm, ceramic particles are filled in liquid plastic to form an inorganic matrix with 80% ceramic
