Suitable for soldering work on electrical components and devices such as circuit boards, PCBs, SMDs, DIP, cables, televisions, headphones, or microphones. The integrated flux ensures particularly comfortable and effective soldering. Flux-cored solder wire with a thin diameter of 1 mm for easy dosing and soldering of delicate components. High proportions of silver and copper Sn3.5Ag0.7Cu provide optimized flow behavior and improved surface quality when soldering without lead. Easy, homogeneous wetting of the solder joint due to the rosin flux core. No-clean solution with continuous flux residues that eliminate the need for cleaning the solder joint after use. Reduced spattering behavior for increased user safety and protection of the workpiece. Halogen-free and with low smoke emission. Perfect for soft soldering at low temperatures in both machine and hand soldering applications.
