Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auftragen von mehrkomponentigen Auftragmassen auf ein Substrat eines Halbleiter-Moduls. Derartige mehrkomponentige Auftragmassen können insbesondere Zweikomponentenkleber und weiterhin auch mehrkomponentige Vergussmassen, z.B. ein zweikomponentiges Silikongel, sein.The The invention relates to a method and a device for applying of multi-component coating compositions on a substrate of a semiconductor module. such multi-component application compounds can in particular two-component adhesives and also multicomponent adhesives Potting compounds, e.g. a two-component silicone gel.
Bei der Verarbeitung von Zweikomponentenklebern werden die beiden Komponenten im Allgemeinen bei der Zuführung zu der Düse der Auftragvorrichtung gemischt. Hierdurch ergibt sich eine maximal zulässige Verweildauer des gemischten Klebers in der Düse. Kleber für elektronische Bauelemente werden hierbei in Hinsicht auf ihre Haftfestigkeit und weiterhin, insbesondere bei der Verarbeitung von Leistungshalbleitern, auf ihre thermische Leitfähigkeit hin optimiert.at the processing of two-component adhesives become the two components generally at the feeder to the nozzle the applicator mixed. This results in a maximum allowed Dwell time of the mixed adhesive in the nozzle. Glue for electronic Components are here in terms of their adhesion and continue, in particular in the processing of power semiconductors, on their thermal conductivity optimized.
Zur Auftragung werden dementsprechend Düsen verwendet, in denen ein Flüssigkeitsstrahl mit hinreichender Schnelligkeit aufgetragen werden kann. Hierbei können nicht allzu feine Düsen verwendet werden, da eine feine Düse, d.h. Düse mit geringem Innendurchmesser, durch die sich vermischenden Komponenten verstopfen könnte.to Accordingly, nozzles are used in which a liquid jet can be applied with sufficient speed. in this connection can not too fine jets be used because a fine nozzle, i. Small inner diameter nozzle, could clog up by the mixing components.
Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung weisen demgegenüber insbesondere den Vorteil auf, dass eine feine Dosierung und genaue Positionierung einer mehrkomponentigen Auftragmasse auf dem Substrat des Moduls möglich ist. Hierbei können insbesondere genau positionierte und dimensionierte, dünn beschichtete Klebepunkte aufgebracht werden.The inventive method and the device according to the invention show in contrast in particular the advantage that a fine dosage and accurate Positioning of a multi-component application compound on the substrate of the module possible is. Here you can especially accurately positioned and dimensioned, thin coated Adhesive dots are applied.
Weiterhin können zusätzlich zu den Klebepunkten z.B. Zwischenräume zwischen den Klebepunkten mit einer geeigneten Wärmeleitmasse gefüllt werden, so dass eine verbesserte Ableitung der Verlustleistung der verklebten Baugruppen möglich ist. Hierbei kann z.B. das Mikro-Dosierventil zum Auftragen der Wärmeleitmasse in anderem Abstand zum Substrat angeordnet werden und somit anders fokussieren. Auch zur Passivierung vorgesehene Auftragmassen, wie z.B. mehrkomponentige Silikongele, können genau dosiert und dünnschichtig und somit materialsparend aufgetragen werden.Farther can additionally to the sticking points e.g. Spaces between the glue dots with a suitable thermal compound to be filled so that improved dissipation of the power dissipation of the glued Modules possible is. Here, e.g. the micro dosing valve for applying the thermal compound be arranged at a different distance to the substrate and thus different focus. Also for passivation envisaged order quantities, such as e.g. multi-component silicone gels, can be precisely dosed and thin-layered and thus be used to save material.
Erfindungsgemäß werden ein Verfahren und eine Vorrichtung zum Auftragen von Auftragmassen auf ein Substrat geschaffen; als Substrat kann hierbei z.B. ein Gehäuse, eine Leiterplatte oder ein Keramik-Substrat dienen, es kann bei der Herstellung von Chip-Stapeln z.B. der Flip-Chip-Technologie oder Stack-Chip-Technologie jedoch z.B. auch ein Chip als Substrat dienen. Weiterhin wird ein Verfahren zum Herstellen eines Moduls geschaffen, bei dem zunächst Klebepunkte mittels des erfindungsgemäßen Auftragsverfahrens aufgebracht werden und auf den Klebepunkten nachfolgend Bauelemente befestigt werden. Hierbei können Module mit genauer Positionierung und definierter Schichtdicke des Klebers erzeugt werden.According to the invention a method and apparatus for applying application compounds created a substrate; as a substrate, e.g. a housing, a PCB or a ceramic substrate, it can in the production of chip stacks e.g. the flip chip technology or stack chip technology however, e.g. also serve as a substrate for a chip. Furthermore, a A method of making a module is provided in which first adhesive dots by means of the application method according to the invention be applied and subsequent to the adhesive dots components be attached. Here you can Modules with exact positioning and defined layer thickness of the Glue be generated.
Die Auftragung der mehreren Komponenten der Auftragmasse kann auch alternierend mehrschichtig erfolgen, wobei auf einer ersten Schicht der ersten Komponente eine erste Schicht der zweiten Komponente aufgetragen wird, nachfolgend eine zweite Schicht der ersten Komponente, nachfolgend eine zweite Schicht der zweiten Komponente. Hierbei können zwei oder auch mehr Schichtfolgen aufgetragen werden, wodurch eine gute Durchmischung der Komponenten erreicht wird.The Application of the multiple components of the application compound can also be alternating multilayered, wherein on a first layer of the first Component applied a first layer of the second component hereinafter, a second layer of the first component, hereinafter a second layer of the second component. Here, two or more layer sequences be applied, resulting in a good mixing of the components is reached.
