Elektronisch samenstelElectronic assembly
De uitvinding heeft betrekking op een elektronisch samenstel met een elektronische ketenplaat en een halfgeleiderpakket, dat is voorzien van elektrische geleiders die zijwaarts uitsteken uit het pakket en in 5 elektrische verbinding staan met de ketenplaat, een koelpiaat die een eerste oppervlak bezit, dat in mechanisch contact staat met een oppervlak van het pakket en veerkrachtige bevestigingsorganen die samenwerken met een tweede oppervlak van de koelpiaat en met een gedeelte van het pakket dat zich bevindt tegenover het genoemde oppervlak voor het fixeren van het pakket tegen het eerste oppervlak van de koelpiaat.The invention relates to an electronic assembly with an electronic circuit board and a semiconductor package, which is provided with electric conductors protruding sideways from the package and in electrical connection with the chain plate, a cooling plate having a first surface, which is in mechanical contact with a package surface and resilient fasteners cooperating with a second surface of the cooling plate and with a portion of the package opposite said surface for fixing the package against the first surface of the cooling plate.
10 Een dergelijk samenstel is bekend uit het Duitse Gebrauchsmuster 81 30 512. in het bijzonder beschrijft deze publicatie een klem voor het bevestigen van koelplaten aan transistoren en dioden. De bekende constructie lijkt niet zonder meer geschikt voor toepassing op meer ingewikkelde halfgeleiderpakketten die met gedrukte ketenpanelen moeten worden verbonden.Such an assembly is known from German Gebrauchsmuster 81 30 512. In particular, this publication describes a clamp for attaching cooling plates to transistors and diodes. The known construction does not seem readily suitable for application to more complicated semiconductor packages to be connected with printed circuit panels.
Een samenstel geschikt voor meer ingewikkelde halfgeleiderpakketten wordt beschreven in de Italiaanse 15 octrooiaanvrage No. 20505 A/85 van 26 april 1985, waarop inmiddels het Italiaanse octrooi 1 215 269 werd verleend. Het in die publicatie beschreven stelsel is van het schroeftype. Een dergelijk stelsel van het schroeftype vergroot de mechanische hechting tussen het elektronische pakket en de koelpiaat aanzienlijk, waardoor de kans, dat het pakket zich naar boven beweegt, waardoor een ongewenste thermische dissipatieweerstand ontstaat, wordt verkleind. De hoogte van de schroefkop is groter dan de hoogte van 20 hetzij de klem hetzij het pakket, waardoor wordt voorzien in een meer directe of positieve kracht, welke op de klem wordt uitgeoefend. De positieve klemkracht, die direct op het elektronische pakket wordt uitgeoefend, naast het aanbrengen van een buigzaam thermisch materiaal tussen het pakket en de koelpiaat, vergroot de warmtedissipatie, hetgeen neerkomt op een belangrijke verbetering ten opzichte van de stand der techniek. Ofschoon de bovengenoemde octrooiaanvrage leidt tot het verschaffen van een meer 25 significante mechanische hechting, strekken de geleiders uit het pakket in de bovengenoemde octrooiaanvrage zich voor het koppelen met de keten uit slechts één zijde van het pakket uit, dat aan de uitwendige warmteafvoerinrichting is bevestigd. Deze uitvoeringsvorm beperkt het aantal geleiders voor koppeling met het ketenpaneel, waardoor het gebruik van meer uitgebreide kosten wordt beperkt.An assembly suitable for more complicated semiconductor packages is described in Italian Patent Application No. 20505 A / 85 of April 26, 1985, to which Italian patent 1 215 269 has since been granted. The system described in that publication is of the screw type. Such a screw-type system greatly increases the mechanical bond between the electronic package and the cooling plate, thereby reducing the chance of the package moving upward, creating an undesirable thermal dissipation resistance. The height of the screw head is greater than the height of either the clamp or the package, thereby providing a more direct or positive force applied to the clamp. The positive clamping force applied directly to the electronic package, in addition to providing a flexible thermal material between the package and the cooling plate, increases heat dissipation, representing a significant improvement over the prior art. Although the above-mentioned patent application results in providing a more significant mechanical adhesion, the package conductors in the above-mentioned patent application extend for coupling to the chain from only one side of the package attached to the external heat sink. This embodiment limits the number of conductors for coupling to the chain panel, limiting the use of more extensive costs.
Er bestaat derhalve vraag naar een inrichting en werkwijze voor het thermisch koppelen van pakketten 30 van elektronische componenten met een koelpiaat, welke een betrekkelijk gemakkelijk inbrengen en verwijderen van het pakket mogelijk maakt en voorziet in een grotere flexibiliteit bij de positionering van het elektronische pakket of de component, welke een koeling vereist, terwijl het tevens mogelijk wordt gemaakt, dat pakketten met een aantal geleiders aan meer dan één zijde daarvan (door oppervlaktemontage) met een ketenpaneel worden gekoppeld.Hence, there is a demand for a device and method for thermally coupling packages 30 of electronic components with a cooling plate, which allows relatively easy insertion and removal of the package and provides greater flexibility in the positioning of the electronic package or the component, which requires cooling, while also allowing packages with multiple conductors on more than one side thereof (by surface mounting) to be coupled to a chain panel.
35 Derhalve is het doel van de uitvinding het verschaffen van een verbeterd elektronisch samenstel met warmteafvoerkoppelmechanisme voor een halfgeleiderpakket.Therefore, the object of the invention is to provide an improved electronic assembly with heat sink coupling mechanism for a semiconductor package.
Het gestelde doel wordt bereikt met een samenstel van een in de aanhef genoemde soort, dat volgens de uitvinding wordt gekenmerkt, doordat de ketenplaat is opgesteld op het eerste oppervlak van de koelpiaat en nabij een rand daarvan is voorzien van een opening die bestemd is voor het onderbrengen van 40 het pakket, zodanig dat het pakket ten minste één zijde heeft die niet is omgeven door de ketenplaat en die toegankelijk is voor de veerkrachtige bevestigingsorganen teneinde de fixatie van het pakket aan de koelpiaat te verzekeren.The stated object is achieved with an assembly of the type mentioned in the preamble, which is characterized according to the invention in that the chain plate is arranged on the first surface of the cooling plate and is provided with an opening near the edge thereof for the purpose of accommodating the package such that the package has at least one side which is not surrounded by the chain plate and which is accessible to the resilient fasteners to ensure fixation of the package to the cooling plate.
Bij de constructie volgens de uitvinding kunnen de geleiders van het halfgeleiderpakket zich aan meer dan één zijde zijwaarts uitstrekken hetgeen een grotere ketenkoppelflexibiliteit meebrengt.In the construction according to the invention, the conductors of the semiconductor package can extend laterally on more than one side, which entails greater chain coupling flexibility.
45 Op geschikte wijze kan het samenstel volgens de uitvinding van een warmtegeleidend materiaal zijn voorzien, dat tussen het pakket en het eerste oppervlak van de koelpiaat is opgesteld. Dit bevordert een goede warmteafvoer.The assembly according to the invention can suitably be provided with a heat-conducting material, which is arranged between the package and the first surface of the cooling plate. This promotes good heat dissipation.
De uitvinding wordt toegelicht onder verwijzing naar de tekening. Daarbij toont: 50 figuur 1a een verticaal aanzicht van een inrichting voor het afvoeren van warmte van een halfgeleiderpakket overeenkomstig een uitvoeringsvorm van de bovengenoemde Italiaanse aanvrage; figuur 1b een perspectivisch aanzicht van de inrichting volgens figuur 1a; figuur 2a een doorsnede in de richting van de pijlen x-x, als aangegeven in figuur 2b, van een inrichting voor warmteafvoer van een halfgeleiderpakket met geleiders aan meer dan één zijde van het pakket 55 overeenkomstig de uitvinding; en figuur 2b een perspectivisch aanzicht van de inrichting volgens figuur 2a.The invention is explained with reference to the drawing. In the drawing: Fig. 1a shows a vertical view of a device for removing heat from a semiconductor package according to an embodiment of the above-mentioned Italian application; figure 1b shows a perspective view of the device according to figure 1a; Figure 2a shows a cross-section in the direction of arrows x-x, as indicated in Figure 2b, of a semiconductor package heat sink device with conductors on more than one side of the package 55 according to the invention; and figure 2b shows a perspective view of the device according to figure 2a.
