Ein Nachteil bei den bekannten Verfahren ist darin zu sehen, dass bei Aushärten des Klebstoffs sehr hohe Temperaturen erforderlich sind, welche zu einem Verzug des Substrats fuhren. Deshalb war es bekannt, den Prozess des Erwärmens und des Abkühlens sehr langsam durchzuführen, damit ein Ausgleich des Substrats möglich wird.One Disadvantage of the known methods is the fact that at Harden the adhesive requires very high temperatures, which lead to a delay of the substrate. Therefore, it was known the Process of heating and cooling to perform very slowly, so that a balance of the substrate is possible.
Dieser sehr lange Prozess ist jedoch unwirtschaftlich und benötigt auch eine hohe Aufnahmekapazität.This However, a very long process is uneconomical and also requires a high absorption capacity.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen zur Beschleunigung des Aushärteprozesses und gleichzeitiger Verringerung der Verzugsneigung.Of the Invention is based on the object, a method and an apparatus to provide for accelerating the curing process and at the same time Reduction of the tendency to warp.
Diese Aufgabe wird durch die Merkmale des Verfahrensanspruch 1 und des Vorrichtungsanspruchs 7 gelöst.These The object is achieved by the features of method claim 1 and of Device claim 7 solved.
Der wesentliche Vorteil des Verfahrens zum Befestigen von Bauteilen auf einem Substrat liegt darin, dass das Substrat selbst in unmittelbarem Kontakt mit einer Heizplatte steht, wobei diese Heizplatte gleichzeitig die Stabilisierung der Leiterplatte vornimmt. Außerdem ist eine Gegendruckplatte vorgesehen, damit kann das bestückte Substrat gespannt werden, so dass die Wärmeeinwirkung nicht zu einem Verzug des Substrats führt. Ferner weist die Gegendruckplatte Aussparungen zur Reduzierung der Wärmeübertragung auf bestimmte Bauteile auf.Of the significant advantage of the method for attaching components on a substrate lies in that the substrate itself is in immediate Contact with a hot plate stands, with this hot plate at the same time the stabilization of the circuit board makes. There is also a counter pressure plate provided, so that can be equipped Substrate are clamped so that the heat does not cause a Delay of the substrate leads. Furthermore, the counter-pressure plate has recesses for reducing the heat transfer on certain components.
In einer Ausgestaltung der Erfindung ist die Gegendruckplatte ebenfalls eine Heizplatte, dies hat den Vorteil, dass kein Wärmeverlust in Richtung Gegendruckplatte erfolgt. Diese zusätzliche Heizplatte muss nicht zwingend notwendig den Klebstoff zusätzlich erwärmen, es genügt eine Erwärmung die einen Temperaturverlust ausgleicht.In An embodiment of the invention, the counter-pressure plate is also a heating plate, this has the advantage that no heat loss takes place in the direction counterpressure plate. This additional hot plate does not have to It is absolutely necessary to heat the adhesive additionally, one is enough warming which compensates for a temperature loss.
Weiterbildungsgemäß wird das Substrat nach der Aushärtung des Klebstoffs auf einem Transportband in eine Kühlstation transportiert, wobei bei dem Transport eine Zusatzunterstützung bzw. eine Vorrichtung zum Verhindern der Durchbiegung vorgesehen ist.Further education is the Substrate after curing transported the adhesive on a conveyor belt in a cooling station, wherein during transport an additional support or a device is provided for preventing the deflection.
Nach der Abkühlung kann das Substrat in ein Magazin transportiert 1 werden.To the cooling the substrate can be transported into a magazine 1.
Weiterbildungsgemäß ist die Gegendruckplatte bzw. die Heizplatte wärmeisoliert, so dass Wärme nur in geringem Umfang nach außen abstrahlen kann.Training is the Counterpressure plate or the heating plate is thermally insulated, so that heat only to a small extent to the outside can radiate.
Es besteht auch die Möglichkeit über das gesamte Substrat oder über einen Teil der Leiterplatte vorgewärmtes Gas einzuleiten, beispielsweise vorgewärmter Stickstoff. Diese Zusatzmaßnahme erhöht die Aushärtegeschwindigkeit erheblich.It there is also the possibility of that entire substrate or over to initiate a portion of the circuit board preheated gas, for example preheated Nitrogen. This additional measure elevated the curing speed considerably.
Der weitere Vorteil der Einleitung von vorgewärmtem Stickstoff liegt darin, dass Oxidation vermieden wird und eine Ausgasung des Kleber aus dem Substratbereich verdrängt werden kann. Damit wird gleichzeitig auch vermieden, dass sich die Ausgasung des Klebers auf dem Substrat niederschlägt und so zu Problemen in nachfolgenden Prozessen führt.The further advantage of the introduction of preheated nitrogen is that oxidation is avoided and outgassing of the adhesive from the substrate region can be displaced. This also prevents the outgassing of the adhesive from being deposited on the substrate and thus leads to problems in subsequent processes.
Die Durchführung der Kühlung nach dem Aushärten erfolgt in einer Ausgestaltung der Erfindung mit Kühlplatten, welche beispielsweise ein Pellier- Element aufweisen. Es besteht auch die Möglichkeit, die Kühlplatten mit Kaltwasser oder mit Luft zu kühlen.The execution the cooling after curing takes place in one embodiment of the invention with cooling plates, which have, for example, a pelleting element. It exists also the possibility the cooling plates to cool with cold water or with air.
Die Erfindung bezieht sich auch auf eine Vorrichtung zur Befestigung von Bauteilen auf einem Substrat wobei diese Vorrichtung vorteilhafterweise mit einer Linearführung versehen ist, wobei die Heizplatte oder die Gegendruckplatte über diese Linearführung verschoben werden kann, so dass das Substrat zwischen Gegendruckplatte und Heizplatte spannbar ist.The The invention also relates to a device for fastening of components on a substrate, this device advantageously with a linear guide is provided, wherein the heating plate or the counter-pressure plate on this linear guide can be moved so that the substrate between counterpressure plate and heating plate is tensioned.
In einer weiteren Ausgestaltung der Vorrichtung ist die Heizung eine Flächenheizung, diese kann an einer auswechselbaren Adapterplatte angeordnet sein, damit besteht die Möglichkeit unterschiedliche Profile oder Heizplatten mit unterschiedlichen Aussparungen einzusetzen. Diese und weitere Merkmale gehen nicht nur aus den Ansprüchen sondern auch aus der Beschreibung hervor.In In a further embodiment of the device, the heater is a Surface heating, this can be arranged on an exchangeable adapter plate, there is the possibility different profiles or heating plates with different Insert recesses. These and other features do not work only from the claims but also from the description.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.The The invention will be explained in more detail with reference to embodiments.
Es zeigt:It shows:

Draufsicht auf die Adapterplatte
Es besteht die Möglichkeit, die Adapterplatte mit den Wärmeübertragungselementen austauschbar zu gestalten, damit lässt sich die gesamte Einrichtung sehr schnell auf unterschiedliche Substrate bzw. Substratgestaltungen anpassen.It it is possible, the adapter plate with the heat transfer elements to make interchangeable, so that can be the entire device very fast on different substrates or substrate designs to adjust.
Um mögliche Ausgasungen des Klebers zu beseitigen ist es möglich, entweder im Bereich der untern Heizplatte Absaugkanäle zu integrieren, oder aber den gesamten Prozessbereich mit einer Absaugung zu versehen. Bei Vorliegen bestimmter Vorraussetzungen ist es möglich, auf eine Kühlung der Substrate nach dem Aushärten des Klebers zu verzichten. Und zwar dann, wenn die Substrate die bei der geforderten Härtetemperatur oder Härtedauer nur unwesentliche mechanische Durchbiegung zeigen oder beim Einsatz von Klebern, die bei niedrigen Temperaturen oder kurzen Zeiten ausgehärtet werden können.Around possible It is possible to eliminate outgassing of the glue either in the area the lower heating plate suction channels integrate, or the entire process area with a To provide suction. In case of certain prerequisites Is it possible, on a cooling the substrates after curing to dispense with the glue. And that is when the substrates are the at the required hardening temperature or hardening time only show insignificant mechanical deflection or in use of adhesives that are cured at low temperatures or short times can.
