Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine einen Sensor aufweisende Multilayerleiterplatte nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Bearbeitung einer Multilayerleiterplatte.The The invention relates to a sensor having a multilayer printed circuit board according to the preamble of claim 1 and a method for processing a multilayer PCB.
Hintergrund der ErfindungBackground of the invention

Multilayerleiterplatte ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine mindestens einen Sensor aufweisende Multilayerleiterplatte anzugeben, welche insbesondere zur Verwendung in einem Elektromotor geeignet ist.Of the Invention is based on the object, at least one sensor specify multilayer printed circuit board indicate which particular suitable for use in an electric motor.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Multilayerleiterplatte mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zur Bearbeitung einer Multilayerleiterplatte mit den Merkmalen des Anspruchs 12. Im Folgenden im Zusammenhang mit der Leiterplatte erläuterte Ausgestaltungen und Vorteile gelten sinngemäß auch für das Verfahren und umgekehrt.These The object is achieved by a multilayer printed circuit board with the features of claim 1 and by a method for processing a multilayer printed circuit board with the features of claim 12. Hereafter With the circuit board explained embodiments and advantages apply mutatis mutandis to the process and vice versa.
Die Multilayerleiterplatte weist einen Toplayer, einen Bottomlayer sowie mindestens einen Zwischenlager auf, wobei ein Sensor unmittelbar auf einen Zwischenlager aufgelötet ist. Um die Anbringung des Sensors auf dem Zwischenlager zu ermöglichen, wird in die Leiterplatte eine Vertiefung eingebracht, insbesondere gefräst, welche genau bis zu einem bestimmten Lager reicht.The Multilayer board has a top layer, a bottom layer as well at least one intermediate storage, with a sensor immediately soldered onto an intermediate storage. To attach the To enable sensors on the intermediate storage is in the PCB introduced a recess, in particular milled, which reaches exactly to a certain camp.
Vorzugsweise umfasst die Multilayerleiterplatte insgesamt mehr als zwölf Lager, das heißt mehr als zehn auch als Innen-Layer bezeichnete Zwischenlager. Vom Toplayer aus gezählt befindet sich der Sensor beispielsweise auf dem zwölften, dem dreizehnten, dem vierzehnten oder einem noch weiter vom Toplayer entfernten Lager. Der Toplayer ist dabei derjenige Lager, von welchem aus die sacklochartige Vertiefung in die Leiterplatte eingebracht wird.Preferably In total, the multilayer board includes more than twelve Bearing, that is, more than ten, also referred to as inner layer Interim storage. Counted from the top layer is the Sensor on the twelfth, the thirteenth, for example the fourteenth or even further away from the top layer camp. The top layer is the one bearing, from which the blind hole-like Well is introduced into the circuit board.
Der Vorschub des Fräswerkzeugs, welches die Vertiefung, in der der Sensor angeordnet werden soll, erzeugt, wird automatisch gestoppt, sobald ein elektrischer Kontakt zwischen dem Fräswerkzeug und leitendem Material desjenigen Lagers, mit dem der Sensor zu verbinden ist, hergestellt ist. Die Genauigkeit in Vorschubrichtung bei dem Fräsvorgang beträgt beispielsweise ±5 μm.Of the Feed of the milling tool, which the recess, in which the sensor is to be arranged generates automatically stopped as soon as an electrical contact between the milling tool and conductive material of that bearing to connect to the sensor is, is made. The accuracy in the feed direction at the Milling process is for example ± 5 microns.
Der auf einem Zwischenlager der Multilayerleiterplatte angebrachte Sensor ist beispielsweise ein Temperatur-Sensor oder ein Magnetfeld-Sensor, insbesondere ein Hall-Sensor.Of the mounted on an intermediate storage of multilayer PCB sensor is for example a temperature sensor or a magnetic field sensor, in particular a Hall sensor.
In bevorzugter Ausgestaltung ragt der Sensor nicht über den Querschnitt der Multilayerleiterplatte hinaus. Ein mechanischer Schutz des Sensors kann auf einfache Weise durch ein elektrisch isolierendes Füllmaterial, beispielsweise ein Harz, insbesondere ein Zweikomponenten-Harz, bereitgestellt werden, welches in die Vertiefung der Multilayerleiterplatte gefüllt wird, in welcher der Sensor angeordnet ist. Die Anordnung des Sensors innerhalb der Multilayerleiterplatte ist zum Einen besonders platzsparend und ermöglicht zum anderen eine besonders exakte Erfassung von Zuständen, beispielsweise Temperaturen, welche in der Leiterplatte herrschen.In preferred embodiment, the sensor does not protrude over the Cross section of the multilayer PCB. A mechanical one Protection of the sensor can be easily done by an electric insulating filling material, for example a resin, in particular a two-component resin provided in the Deepening of the multilayer printed circuit board is filled, in which the sensor is arranged. The arrangement of the sensor inside The multilayer PCB is on the one hand particularly space-saving and on the other hand allows a particularly accurate detection of states, for example, temperatures, which in the PCB dominate.
Gemäß einer vorteilhaften Weiterbildung weist zumindest ein Lager der Multilayerleiterplatte eine elektrisch leitende, von umgebenden Strukturen elektrisch isolierte Kühlfläche auf. Diese Kühlfläche ist aus demselben Material wie die Leiterbahnen des Lagers hergestellt und sorgt insbesondere für eine Vergleichmäßigung der thermischen Belastung der Multilayerleiterplatte.According to one advantageous development, at least one bearing of the multilayer printed circuit board has a electrically conductive, electrically isolated from surrounding structures Cooling surface on. This cooling surface is made of the same material as the tracks of the camp and in particular ensures a homogenization the thermal load of the multilayer printed circuit board.
Von besonderem Vorteil ist die Ausstattung der Multilayerleiterplatte mit Kühlflächen in Anwendungsfällen, in denen die die Kühlflächen umgebenden leitenden Strukturen der Lager elektrische Spulen bilden.From particular advantage is the equipment of the multilayer printed circuit board with cooling surfaces in applications, in which the cooling surfaces surrounding conductive Structures of the bearings form electrical coils.
Die Multilayerleiterplatte wird bevorzugt als Bauteil eines PCB(printed circuit board)-Motors verwendet. Hierbeit kann es sich um einen Rotativ- oder um einen Linear-Elektromotor handeln. Auch elektrische Antriebe, welche der direkten Erzeugung kombinierter linearer und rotativer Bewegungen dienen, sind unter Verwendung der Multilayerleiterplatte herstellbar. Im Fall eines rotativen elektrischen Antriebs bildet die Multilayerleiterplatte vorzugsweise einen bestrombaren Stator des Elektromotors. Der Rotor des rotativen elektrischen Antriebs ist dagegen in vorteilhafter Ausgestaltung mit Permanentmagneten, insbesondere Seltenerdmag neten, besetzt, sodass keine Stromzuführung zu rotierenden Teilen erforderlich ist. Im Unterschied hierzu ist bei linearen elektrischen Antrieben die Multilayerleiterplatte dagegen bevorzugt Teil des Läufers der Antriebsvorrichtung. Der Läufer kann durch diese Gestaltung besonders gewichtssparend ausgelegt werden, womit hohe Beschleunigungen des Linearmotos realisierbar sind.The multilayer printed circuit board is preferably used as a component of a PCB (printed circuit board) motor. This can be a rotary or a linear electric motor. Electric drives, which serve the direct generation of combined linear and rotary movements, can also be produced by using the multilayer printed circuit board. In the case of a rotary electric drive, the multilayer printed circuit board preferably forms a currentable stator of the electric motor. The rotor of the rotary electric drive, however, in an advantageous embodiment with permanent magnets, in particular rare earth magnets, occupies, so that no power supply to rotating parts is required. By contrast, in the case of linear electric drives, by contrast, the multilayer printed circuit board is preferably part of the rotor of the drive device. The runner can be designed by this design particularly weight-saving, so high Be accelerations of the linear motor can be realized.
