Haube zur vakuumdichten Abdeckung von Multilayem. Robert Bürkle GnibH & Co., PO Box 160, D-7290 Freudenstadt
Hood for vacuum-tight covering of multilayers.
Die Erfindung betrifft eine Haube zum Verpressen einer mehrlagigen Leiterplatte (Multilayer) für die Elektrotechnik/Elektronik.The invention relates to a hood for pressing a multilayer printed circuit board (multilayer) for electrical engineering/electronics.
Zum Verpressen eines Multilayers in einer Vakuum-Presse ist eine druckbeständige, vakuumdichte und temperaturbeständige Abdeckung erforderlich.To press a multilayer in a vacuum press, a pressure-resistant, vacuum-tight and temperature-resistant cover is required.
Bisher werden die Multilayer meist individuell in eine Folie eingewickelt und mit Klebestreifen abgedichtet. Der Nachteil hierbei ist, daß Folie sowie Klebestreifen nur einmalig verwendet \«rdcji kühnen. Außerdem ist die Verpackung labil und demzufolge eine mechanische Zerstörung während des Preßvorganges möglich.Up to now, the multilayers have usually been individually wrapped in foil and sealed with adhesive tape. The disadvantage here is that the foil and adhesive tape can only be used once. In addition, the packaging is unstable and mechanical damage during the pressing process is therefore possible.
Als Alternative hierzu ist eine wiederverwendbare Haube bekarmx, die ein Paket von Multilayem gleichzeitig abdeckt, die jedoch den Nachteil hat., daß sie nur für die bestimmte Multilayer-Paketgröße verwendet werden kann, für die sie ausgelegt ist.An alternative to this is a reusable hood that covers a package of multilayers at a time, but has the disadvantage that it can only be used for the specific multilayer package size for which it is designed.
Da eine Presse bis zu 15 Pakete auinimmt und es sehr viele Paketgrößen gibt, sind die Investitionskosten fUr eine Vielzahl von ite-jiben in den erforderlichen Größen bei einem relativ hohen Einzelpreis, erheblich.Since a press can hold up to 15 packages and there are many package sizes, the investment costs for a large number of ite-jibs in the required sizes at a relatively high unit price are considerable.
• · I t• · I t
Aufgabe der Erfindung ist deshalb, eine solche Haube so weiterzubilden, daß ein Haubentyp Tür alle praktisch auftretenden Größen von Multilayem verwendet werden kann.The object of the invention is therefore to develop such a hood in such a way that one hood type door can be used for all practically occurring sizes of multilayers.
Diese Aufgabe wird erfindingsgemäß dadurch gelöst, daß sie aus einer hochelastischen, mattenartigen Folie besteht, die Über einen Rahmen gezogen j st, der auf seiner Unterseite über eine umlaufende Randdichtung auf der Grundplatte aufsetzbar ist. This object is achieved according to the invention in that it consists of a highly elastic, mat-like film that is pulled over a frame that can be placed on the base plate on its underside via a circumferential edge seal.
Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung wird anhand von Zeichnungen näher erläutert.An embodiment of the device according to the invention is explained in more detail with reference to drawings.

Figur 2: eine Draufsicht auf die Haube.Figure 2: a top view of the hood.
Lin Multilayerpaket 1 ist zwischen zwei Werkzeugplatten 2 und 2' planparallel ausgerichtet und auf eine Grundplatte 3 aus Aluminium gelegt. Über dieses Multilayerpaket 1 und auf die Grundplatte 3 ist die Haube aufgelegt. Sie besteht aus einer Silikonmatte 4, einer Randdichtung 5, beispielsweise einem Silikonschlauch, einem Metallrahmen 6 und einer Klemmleiste 7 mit einer Anzahl von Schrauben Die Silikonmatte 4 ist aus einem hochelastischen Gummimaterial, das vakuumdicht und bis zum achtfachen seiner Grundlänge dehnbar ist.The multilayer package 1 is aligned parallel to one another between two tool plates 2 and 2' and placed on an aluminum base plate 3. The hood is placed over this multilayer package 1 and on the base plate 3. It consists of a silicone mat 4, an edge seal 5, for example a silicone hose, a metal frame 6 and a clamping strip 7 with a number of screws. The silicone mat 4 is made of a highly elastic rubber material that is vacuum-tight and can be stretched up to eight times its basic length.
Das zum Verpressen des Multilayerpaketes erforderliche Vakuum wird über Bohrungen 3A in der Grundplatte 3 erzeugt, wobei die Silikonmatte 4 das Multilayerpaket 1 dann infolge des durch Pfeile (Figur 1) angedeuteten äußeren Gasdruckes vakuumdicht umschließt.The vacuum required to press the multilayer package is generated via holes 3A in the base plate 3, whereby the silicone mat 4 then encloses the multilayer package 1 in a vacuum-tight manner as a result of the external gas pressure indicated by arrows (Figure 1).
