Description

In dem Hauptpatent ist ein Lötkolben beschrieben, bei dem die an dem wärmezuführenden Körper angebrachte Lötfinne oder Lötspitze aus einem verzunderungsschwachen S und an sich nicht oder nur schwer mit flüssigem Lot benetzbaren porigen Werkstoff, z. B. aus porigem Nickel, Eisen oder einem ähnlichen Werkstoff besteht, der mit flüssigem ■ Lot getränkt ist. Die Herstellung dieser Lötfinne oder Lötspitze erfolgt durch Sintern von Pulver aus verzunderungsschwachem Metall zu dem Zwecke, einen Lötkolben zu schaffen, dessen Lötfinne oder -spitze ohne mechanische Reinigung auf lange Zeit arbeitsfähig bleibt.In the main patent, a soldering iron is described in which the heat to be supplied Body-attached soldering fin or soldering tip from a low-scaling solder S and not or only with difficulty wettable with liquid solder porous material, z. B. made of porous nickel, iron or a similar material that is mixed with liquid ■ The solder is soaked. This soldering fin or tip is made by sintering Powder of low-scaling metal for the purpose of creating a soldering iron, whose soldering fin or tip remains operational for a long time without mechanical cleaning.

Die Erfindung gibt eine zweckmäßige Weiterbildung des Gedankens des Hauptpatents an und besteht darin, daß das gleiche Metall zum Zwecke der Werkstoffersparnis und der einfachen und dauerhaften Befestigung der Lötfinne oder Lötspitze auf der wärmezuführenden Unterlage auf dem Tauch- oder Spritzwege auf die wärmezuführende Unterlage als festhaftende Schicht aufgebracht und auf ihr aufgesintert ist.The invention is an expedient development of the idea of the main patent and consists in that the same metal for the purpose of material saving and simple and durable Attachment of the soldering fin or soldering tip to the heat-supplying surface on the Dipping or spraying paths are applied to the heat-supplying base as a firmly adhering layer and is sintered on it.

Lötkolben, bei denen die zum Löten dienende Spitze aus einer auf die wärmezuführende Unterlage aufgebrachten Schicht besteht, sind an sich bereits bekannt. Es handelt sich bei den Lötspitzen dieser Kolben jedoch um solche Metalle, die das Lot durch Adhäsionskräfte festhalten. Bei dem Lötkolben nach der Erfindung besteht jedoch die Lötspitze aus einem porigen Metall, welches das Lot durch Kapillarkräfte festhält.Soldering irons in which the tip used for soldering is from one to the heat-supplying tip Base applied layer is already known per se. It deals However, the soldering tips of these pistons are those metals which the solder through adhesive forces hold tight. In the soldering iron according to the invention, however, the soldering tip consists of a porous metal, which the Holds solder in place by capillary forces.

Zur Herstellung der Lötschicht wird beispielsweise das Metallpulver, vorzugsweise Nickelpulver, in einer Flüssigkeit, z.B. Alkohol, angerührt. Man taucht die Unterlage darin ein oder spritzt oder streicht die Aufschwemmung auf die Unterlage auf. Dann wird die Flüssigkeit verdampft und das Ganze einer höheren Temperatur, zweckmäßig etwa 10000 C, ausgesetzt, wodurch sich eine aufgesinterte porige Schicht bildet.To produce the solder layer, for example, the metal powder, preferably nickel powder, is mixed in a liquid, for example alcohol. The substrate is dipped into it or the suspension is sprayed or spread onto the substrate. Then, the liquid is evaporated and the whole exposed to a higher temperature, suitably about 1000 0 C, thereby forming a sintered porous layer.

Da man infolge der großen Lebensdauer derartig hergestellter Lötkörper nur die Spitze oder Finne und die anschließenden Flächen des Lötkörpers mit der porigen Schicht zuSince, due to the long service life of soldering bodies produced in this way, only the tip or fin and the adjoining surfaces of the solder body with the porous layer
