Tin spool SN100C® – SnCu0,7Ni FG 2.2% REL0 0.7 mm 400 g
SN100C® FG is a lead-free flux-cored solder wire from Balver Zinn, developed for professional hand soldering, rework, and electronics production. The product combines the well-documented SN100C® alloy with an REL0-classified flux and is suitable for production, service, and maintenance tasks where high soldering quality and process stability are crucial.
SN100C® is a eutectic tin-copper alloy stabilized with nickel and added germanium to reduce oxidation during the soldering process. This contributes to uniform solder joints, better soldering results, and lower material consumption compared to traditional lead-free alloys.
SN100C® – one of the world's most widely used lead-free solder alloys
SN100C® is widely used today in electronics production as a cost-effective alternative to silver-bearing alloys. The alloy is known for its high process stability and good soldering properties in both manual soldering and industrial soldering processes.
The nickel-stabilized structure contributes to stable solder joints, while germanium helps reduce oxidation and improve the efficiency of the soldering process.
Flux-cored solder wire for precise electronics soldering
This variant is equipped with 2.2% flux and is classified as REL0 according to IPC J-STD-004. The flux supports rapid activation and efficient wetting, making it easier to achieve uniform, high-quality solders.
The 0.7 mm wire diameter is particularly suitable for modern electronics production, where high precision and good control over the solder amount are desired. At the same time, the dimension is versatile enough for assembly, rework, and service tasks.
