Abstract: A method wherein the component to be soldered is placed onto the printed circuit board, whereupon the stirrup electrodes of the soldering mechanism are lowered and the terminal legs of the component are pressed against the printed circuit board with a force. After heating the stirrup electrodes for melting the solder, a further advance of the stirrup electrodes ensues for impressing the terminal legs into the molten solder. The formation of a solder layer between terminal legs and printed circuit board subsequently ensues by reducing the force exerted onto the stirrup electrodes and/or by defined retraction of the stirrup electrodes.

Abstract: A soldering device has two or four stirrup electrodes secured to a soldering stirrup holder and a centrally-arranged suction pipette between the stirrup electrodes for picking up, conveying and placing components onto assigned soldering locations. Sensitive mechanical and electrical parts, particularly machanical guides and electrical contacts are protected against undesired precipitation of soldering vapors that arise during the soldering process. This protection is achieved by an extraction device for solder vapors which includes an annular extraction opening between the suction pipette and the soldering stirrup holder. The extraction opening discharges into an extraction chamber arranged above the soldering stirrup holder and is in communication with at least one extraction port.

Abstract: The soldering apparatus using at least one resistance heated stirrup electrode that is place onto soldering locations on a printed circuit board includes a pivotable suspension of the stirrup electrode. The pivotable suspension is such that a dislocated rotational axis of pivotable suspension lies in a plane of the working surface and extends perpendicular to a long side of the rectangular working surface of electrode and at the center thereof. The working surface of the stirrup electrode thus achieves reliable contact with parts to be soldered. Embodiments having two or four soldering stirrups, each individually pivotly suspended, are also possible.

Abstract: In a soldering device comprising at least one stirrup electrode that is secured to a soldering stirrup holder and is heatable with electrical resistance heating and has two soldering webs lying opposite one another or four soldering webs lying opposite one another in pairs, the working surfaces at the underside of the soldering webs should be capable of being placed exactly parallel onto the soldering location that lies, for example, on a printed circuitboard. This is enabled by a flexible suspension of the soldering stirrup holder which provides a pivot compensation center lying centrally in the plane of the working surfaces. As a result thereof, a reliable contact of the parts to be soldered to one another and to the soldering stirrups is guaranteed.
