The circuit board (1) is connected to at least one connector via at least one connector pin (2).

Description
In elektrischen oder elektronischen Geräten sind die für deren Funktion erforderlichen elektrischen und/oder elektronischen Bauelemente zumeist auf einer oder mehreren Leiterplatten angeordnet. Zur elektrischen Verbindung dieser Bauelemente sind auf Oberflächen oder auf Zwischenlagen einer solchen Leiterplatte Metallisierungsschichten vorgesehen, die durch geeignete Strukturierung Leiterbahnen ausbilden. In electrical or electronic devices required for their function electrical and / or electronic components are usually arranged on one or more circuit boards. For the electrical connection of these components, metallization layers are provided on surfaces or on intermediate layers of such a printed circuit board, which form conductor tracks by suitable structuring.
Aufgrund immer höher werdender Signalfrequenzen mit zum Teil steilen Signalflanken entstehen in solchen elektrischen und/oder elektronischen Geräten hochfrequente Signalanteile, die über die signalführenden Steckerstifte auch bei guter Abschirmung – beispielsweise mittels eines metallischen Gehäuses – nach außen dringen und dort andere Geräte oder Anlagen erheblich stören können. Aus diesem Grunde ist es üblich, zwischen einem signalführenden Steckerstift und einer Masseleitung oder Masseschicht sogenannte Block- bzw. EMV-Kondensatoren anzuordnen, über die hochfrequente Signalanteile nach Masse abgeleitet werden. Diese EMV-Kondensatoren benötigen jedoch, insbesondere bei vielen Steckerstiften, einen erheblichen Platz auf der Leiterplatte. Due to ever higher signal frequencies with sometimes steep signal edges arise in such electrical and / or electronic devices high-frequency signal components that penetrate the signal-carrying connector pins even with good shielding - for example by means of a metallic housing - to the outside and there can significantly disrupt other devices or facilities , For this reason, it is customary to arrange between a signal-carrying pin and a ground line or ground layer so-called block or EMC capacitors, are derived via the high-frequency signal components to ground. However, these EMC capacitors require considerable space on the printed circuit board, especially with many connector pins.
Aus der
Es ist daher die Aufgabe der Erfindung, eine einfachere und kostengünstigere Montage von EMV-Kondensatoren bei einer mehrlagigen Leiterplatte vorzusehen. It is therefore an object of the invention to provide a simpler and less expensive installation of EMC capacitors in a multilayer printed circuit board.
Die Aufgabe wird gelöst durch eine mehrlagige Leiterplatte gemäß Anspruch 1. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben. The object is achieved by a multilayer printed circuit board according to claim 1. Advantageous further developments are specified in the subclaims.
Danach weist die mehrlagige Leiterplatte zumindest eine innerhalb der Leiterplatte angeordnete Metallisierungsschicht auf und ist mit zumindest einem Steckverbinder über wenigstens einen Steckerstift verbunden. Die Metallisierungsschicht weist umlaufend um eine Ausnehmung für den Steckerstift und beabstandet von dieser eine eine Isolierzone bildende Aussparung auf. Zwischen dem benachbart zu der Ausnehmung ausgebildeten Teil der Metallisierungsschicht und dem um die Isolierzone ausgebildeten Teil der Metallisierungsschicht ist zumindest ein, die Isolierzone überbrückender, in die Leiterplatte eingebetteter Kondensator angeordnet. Thereafter, the multilayer printed circuit board has at least one metallization layer arranged within the printed circuit board and is connected to at least one plug connector via at least one plug pin. The metallization layer has circumferentially around a recess for the connector pin and spaced from this on an insulating zone forming recess. Between the adjacent to the recess formed part of the metallization layer and formed around the insulating part of the metallization at least one, the insulating zone bridging, embedded in the circuit board capacitor is arranged.
Dieser EMV-Kondensator benötigt keinen Platz auf der Oberfläche der Leiterplatte und kann auf einfache Weise bereits bei der Herstellung der Leiterplatte montiert werden, ohne eine zusätzliche Bohrung und ein Einsetzen in diese Bohrung und Verlöten zu erfordern. Es kann auf diese Weise eine optimale Anbindung der EMV-Kondensatoren an den Steckerstift einerseits und die Metallisierungsschicht andererseits erfolgen. Da der benötigte Platz für die EMV-Kondensatoren auf der Oberfläche der Leiterplatte wegfällt, kann die Leiterplatte kleiner gestaltet werden. Die EMV-Kondensatoren können näher an der Signalzuleitung des Steckerstifts platziert werden, so dass der parasitäre Antenneneffekt minimiert werden kann. Die Zuverlässigkeit wird durch die eingebettete Aufbau- und Verbindungstechnik erhöht. Zusätzlich besteht ein mechanischer Schutz über die Lebenszeit ebenso wie bei der Montage des Steckers oder des Gehäuses.This EMC capacitor does not require space on the surface of the circuit board and can be easily mounted already in the manufacture of the circuit board, without requiring additional drilling and insertion into this hole and soldering. It can be done in this way an optimal connection of the EMC capacitors to the pin on the one hand and the metallization on the other. Since the space required for the EMC capacitors on the surface of the circuit board is eliminated, the circuit board can be made smaller. The EMC capacitors can be placed closer to the signal lead of the connector pin so that the parasitic antenna effect can be minimized. The reliability is increased by the embedded assembly and connection technology. In addition, there is mechanical protection over the lifetime as well as during assembly of the plug or the housing.
In einer vorteilhaften Weiterbildung der Erfindung sind signalführende Leiterbahnen auf einer der Oberflächen und/oder einer Zwischenschicht der Leiterplatte ausgebildet, wobei zumindest eine davon elektrisch mit dem Steckerstift verbunden ist. In an advantageous development of the invention, signal-carrying printed conductors are formed on one of the surfaces and / or an intermediate layer of the printed circuit board, at least one of which is electrically connected to the plug pin.
Besonders vorteilhaft ist es, wenn der die Isolierzone umgebende Teil der Metallisierungsschicht eine Masseschicht bildet. It is particularly advantageous if the part of the metallization layer surrounding the insulating zone forms a ground layer.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels mit Hilfe einer Figur näher erläutert. Dabei zeigt die The invention will be explained in more detail using an exemplary embodiment with the aid of a figure. It shows the
