Die vorliegende Erfindung betrifft ein elektronisches Bauelement nach dem Oberbegriff von Anspruch 1.The present invention relates to an electronic component according to the preamble of claim 1.
Zur Miniaturisierung elektronischer Schaltkreise werden Halbleiterbauelemente direkt auf einem mit Leitungsbahnen versehenen Träger festgelegt und durch sogenanntes Bonden mit den Leitungsbahnen elektrisch verbunden. Die beim Betrieb der Halbleiterbauelemente als Wärme auftretende Verlustleistung wird über den Träger abgeführt.Semiconductor components are used to miniaturize electronic circuits fixed directly on a carrier provided with conductor tracks and electrically by so-called bonding with the conductor tracks connected. The power loss that occurs as heat during operation of the semiconductor components is dissipated via the carrier.
Dabei hat es sich jedoch als nachteilig erwiesen, daß in dieser Weise aufgebaute elektronische Schaltkreise nur für Halbleiterbauelemente mit kleinen Verlustleistungen geeignet sind. Bei höheren Verlustleistungen ist die Wärmeableitung über die Träger aufgrund ihrer zu geringen Wärmeleitwerte unzureichend. Somit werden die Halbleiterbauelemente derartiger elektronischer Schaltkreise häufig durch Überschreiten der zulässigen Betriebstemperaturen zerstört.However, it has proven to be disadvantageous in this way built-up electronic circuits are only suitable for semiconductor components with low power losses. At higher power losses the heat dissipation via the carrier is insufficient due to their inadequate thermal conductivity. Thus, the semiconductor components Such electronic circuits are often destroyed by exceeding the permissible operating temperatures.
Es stellt sich daher die Aufgabe, ein mit auf der Oberseite eines Trägeis angeordneten Leitungsbahnen verbundenes elektronisches Bauelement zu entwickeln, bei dem auch große Verlustleistungen abgeführt werden können und durch damit verbundene geringe Betriebstemperaturen eine Schädigung des elektronischen Bauelements vermieden wird.There is therefore the task of having one with on top of an inertia to develop electronic components connected to arranged conductor paths, in which large power losses can also be dissipated and the associated low operating temperatures avoid damage to the electronic component.
Diese Aufgabe wird gemäß der vorliegenden Erfindung dadurch gelöst, daß in dem Träger ein Durchbruch vorgesehen ist, in den das elektronische Bauelement einfügbar ist, an der Unterseite des Trägers ein den Durchbruch überdeckender Kühlkörper festgelegt ist und das elektronische Bauelement im Durchbruch auf dem Kühlkörper befestigt ist.This object is achieved according to the present invention in that an opening is provided in the carrier, into which the electronic component can be inserted, and an opening is provided on the underside of the carrier overlapping heat sink is set and the electronic component is fastened in the opening on the heat sink.

Dabei ist der Kühlkörper in vorteilhafter Weise gemäß der Erfindung am Rand des Durchbruchs mit dem Träger verklebt.The heat sink is advantageously according to the invention on Edge of the opening glued to the carrier.
In einer vo teilhaften Ausbildung der Erfindung irt das elektronische Bauelement im Durchbruch auf dem Kühlkörper festgeklebt.In a vo part embodiment of the invention, the electronic irt Component glued to the heat sink in the opening.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Kühlkörper einen in den Durchbruch einpaßbaren Plateaubereich auf und das elektronische Bauelement --«■ auf diesem Plateaubereich festgelegt.In a further advantageous embodiment of the invention, the Heat sink on a plateau area that can be fitted into the opening, and the electronic component is fixed on this plateau area.
Dazu ist es günstig, den Kühlkörper als Kühlblech auszubilden.For this purpose, it is beneficial to design the heat sink as a cooling plate.
Zum Schutz vor störenden mechanischen und chemischen Einflüssen werden das elektronische Bauelement und dessen Anschlußdrähte mit einer isolierenden Abdeckmasse überdeckt.To protect against disruptive mechanical and chemical influences the electronic component and its connecting wires are covered with an insulating covering compound.
Die Vorteile der vorliegenden Erfindung sind insbesondere darin zu sehen, daß bei einer äußerst wirksamen Kühlung des elektronischen Bauelements der Kühlkörper aufgrund seiner Anordnung auf der Unterseite des Trägers die Möglichkeiten des Aufbaus der elektronischen Schaltung auf der Oberseite des Trägers nicht einschränkt. Der Kühlkörper kann dabei in Form und Größe nahezu beliebig gestaltet werden. Darüber hinaus kann ein erfindungsgemäßes elektronisches Bauelement vor dem Verguß mit der isolierenden Abdeckmasse unter Betriebsbedingungen, also im Leistungsbetrieb, erprobt werden, da über den Kühlkörper die gesamte Verlustleistung abgeführt wird. Ein möglicherweise defektes elektronisches Bauelement kann mit dem Kühlkörper aus lern Träger herausgedrückt und durch ein technisch einwandfreies Bauelement ersetzt werden.The advantages of the present invention are particularly to be seen in the fact that, with extremely effective cooling of the electronic component, the heat sink does not restrict the possibilities of constructing the electronic circuit on the upper side of the carrier due to its arrangement on the underside of the carrier. The heat sink can be designed in almost any shape and size. In addition, an electronic component according to the invention can be tested prior to encapsulation with the insulating covering compound under operating conditions, that is to say in power mode, since the entire power loss is dissipated via the heat sink. A possibly defective electronic component can be pushed out of the carrier with the heat sink and replaced by a technically flawless component.
