With the Sensitive Wire Feeder (SWF), Eutect GmbH's intelligent wire feeder can be used in combination with a laser (LL), piston (KL), or induction (IL) system for the soldering of assemblies. In combination with the SWF, the new KL module is a force, wire quantity, and speed-controlled piston soldering system with 100% traceability. Furthermore, the new module is equipped with fully automated changing of the soldering tip and an integrated nitrogen gas supply. With the help of intelligent sensors, the operator is informed when the wire is tending towards the end in the feeder. Here, the system has another 40mm of solder wire in reserve after the signal, in order to be able to complete both the current solder and the process. In addition, the SWF can also be freely integrated into the machine room in its latest stage of development. The SWF KL system adapter, which can be adjusted for optimal soldering results, allows for almost completely free, solid, and reproducible arrangement of the wire feeders and the soldering piston kinematics. The new SWF-KL module can also optionally be equipped with an extraction system. Depending on the overall automation solution, the product to be soldered and the process flow, the extraction system is integrated and minimizes contamination in the system and in the installed components. Thanks to this, service and maintenance periods can be optimized. The freely adjustable speeds and wait and dwell times in the SWF module and in the motorized and spring-loaded piston infeed allows for a maximized process window. The piston soldering itself can also be adjusted for the production conditions and specifications. The piston soldering service life can be maximized through selecting the standby temperature and the functions, depending on the specific soldering process. Alongside the SWF module and the piston soldering application, a new soldering tip changing system was developed. Changing of the soldering tip is done according to the process task or at defined intervals.
