Infrared soldering

This tested infrared soldering process from top and bottom guarantees best results and less broken cells. The patented pre-heating- and downheating unit makes it possible to solder similar to a „reflow“ solder process. The process is very broad and stable. All parameters are stored in our internal data base. Temperature is controlled with the control unit/PC very accurately, reducing the cell stress to an absolute minimum. While the cells are heated up with a controlled profile, soldering temperature is transferred to the cell, only the solder points achieving reliable solder joints. The integrated pre-heating of the cells makes the process much more stabile, because we only need a solder peak at the solder points. Special lamps enable a stress free solderding (patent is pending). Controlled heating cooling after the soldering makes sure that the soldered ribbons do not shrink too fast and do not stress the cells too much. So we can even solder very thin cells. With the special ribbon solder treatment (stretching) the stress is reduced to an absolute minimum with our patented solder solution. Another patent for the stress free soldering is pending. This method was developed with ATN, Dr. Niemeier, a well known solder specialist. Our stringer implements also this patent solutions. Another important feature is our integrated ribbon stretch unit. So every ribbon can be used (even bended ribbons).
