The innovative solder wire tape enables a completely new way of working with hand soldering. The flat tape, filled with flux according to F-SW34, allows for soldering joints in various configurations. The feared spattering of flux, especially during lead-free soldering, is almost completely eliminated. As a result, the circuit board remains significantly cleaner. Additionally, the user's hands are protected. The flux tape is filled with continuous flux cores. Thanks to the no-clean solution, no cleaning of the solder joints is necessary after soldering.
