Description
Die vorliegende Erfindung betrifft eine zur Erdung geeignete oder ableitfähige Haltekomponente (d. h. eine Haltekomponente, die geerdet werden kann) für ein Köühlkörper-Modul.The The present invention relates to a grounding suitable or dissipative holding component (i.e. H. a holding component that can be grounded) for a Köhlkörper module.
In
Chips, die mit hoher Frequenz und starker Leistung arbeiten, z. B. zentrale Recheneinheiten (CPUs), erzeugen während des Betriebs eine elektromagnetische Strahlung, die für andere elektronische Bauteile zu einer elektromagnetischen Störung (EMI) wird. Um eine negative Auswirkung der EMI auf die anderen elektronischen Bauteile zu verringern, muss der Chip somit bezüglich EMI abgeschirmt sein, um eine Intensität der elektromagnetischen Wellen, die vom Chip nach außen strahlen, zu verringern. Eine typische EMI-Abschirmung kann durch den Einbau einer geerdeten Metallabdeckung über dem Chip erreicht werden, wobei eine Masseleitung zum Ableiten der elektrischen Ladung verwendet wird, welche die Metallabdeckung auf einem konstanten elektrischen Potential hält und den erwünschten Effekt erzielt.Crisps, working with high frequency and high power, eg. B. central Processing units (CPUs) generate an electromagnetic during operation Radiation for other electronic components to electromagnetic interference (EMI) becomes. To have a negative impact of EMI on the other electronic To reduce components, the chip must therefore be shielded with respect to EMI, to an intensity the electromagnetic waves that radiate outward from the chip, to reduce. A typical EMI shielding may be through installation a grounded metal cover over the Chip can be achieved, with a ground line for deriving the electrical Charge is used, keeping the metal cover on a constant holding electrical potential and the desired one Achieved effect.
Da auf allen Hochleistungschips ein Kühlkörper-Modul installiert ist, um Wärme abzugeben, und fast alle Kühlkörper- Module aus Metallmaterialien mit hohen Wärmeleitungskoeffizienten hergestellt werden, kann der EMI-Abschirmungseffekt durch Koppeln des Kühlkörper-Moduls mit der Masseleitung erreicht werden. Da ein Befestigungselement des Kühlkörper-Moduls typischerweise ein mit Spritzguss hergestelltes Kunststoffbauteil ist, das nicht elektrisch leitfähig ist, das Kühlkörper-Modul typischerweise durch das Befestigungselement auf dem Chip befestigt wird, nachdem der Chip vollständig installiert wurde, und das Kühlkörper-Modul wahrscheinlich entfernt und neu eingebaut werden muss, wenn der Chip ersetzt werden muss, kann das Kühlkörper-Modul nicht durch Löten geerdet werden. Stattdessen muss ein zusätzliches Metallbauteil verwendet werden, das das Kühlkörper-Modul berührt, und dann kann das Metallbauteil mit der Masseleitung gekoppelt werden. Jedoch sind diese Art von Metallbauteilen, die zum Leiten von Elektrizität verwendet werden, und das Befestigungselement getrennte Bauteile und müssen während der Herstellung getrennt befestigt werden. Außerdem muss das Metallbauteil sorgfältig platziert werden, um einen guten Kontakt zum Kühlkörper-Modul und der Masseleitung der Platine herzustellen. Somit macht die Verwendung des Metallbauteils zur Erdung gemäß dem Stand der Technik die Herstellung kompliziert und gibt Raum für Verbesserungen.There a heatsink module is installed on all high performance chips, for heat and almost all heat sink modules made of metal materials with high heat transfer coefficients can be made, the EMI shielding effect by coupling of the heat sink module be achieved with the ground line. As a fastener of the heat sink module typically a plastic injection molded plastic component is that not electrically conductive is the heatsink module typically secured by the fastener on the chip will be complete after the chip was installed, and the heatsink module probably needs to be removed and reinstalled when the Chip must be replaced, the heatsink module can not be grounded by soldering become. Instead, there must be an additional one Metal component can be used, which touches the heat sink module, and then the metal component can be coupled to the ground line. however These are the types of metal components used to conduct electricity be, and the fastener separate components and must during the Manufacture be attached separately. In addition, the metal component must careful be placed to good contact with the heat sink module and the ground line to produce the board. Thus, the use of the metal component makes for earthing according to the state The technique complicates the production and gives room for improvement.
Vor diesem Hintergrund ist es ein Ziel der vorliegenden Erfindung, eine zur Erdung geeignete oder ableitfähige Haltekomponente (d. h. eine Haltekomponente, die geerdet werden kann, im Folgenden als ableitfähige Haltekomponente bezeichnet) vorzusehen, die einfach zu montieren, zu ersetzen und zu reparieren ist. Die Erfindung soll außerdem sicherstellen, dass die elektrisch leitenden Kontakte zwischen der ableitfähigen Haltekomponente bzw. der Vielzahl deren Erdungsbereichen und der Masseleitung auf der Platine nicht unterbrochen werden.In front In this background, it is an object of the present invention to provide a earthing suitable or dissipative holding component (i.e. a holding component that can be grounded, hereinafter referred to as dissipative Retaining component), which are easy to assemble, to replace and repair. The invention is also intended to ensure in that the electrically conductive contacts between the dissipative holding component or the plurality of grounding areas and the ground line on the board will not be interrupted.
Dies wird durch eine ableitfähige Haltekomponente gemäß dem Anspruch 1 erreicht. Die abhängigen Ansprüche betreffen entsprechende Weiterentwicklungen und Verbesserungen.This is characterized by a dissipative Holding component according to the claim 1 reached. The dependent ones claims concern corresponding further developments and improvements.
