Tin spool SN100C® – SnCu0.7Ni FG 2.2% REL0 0.5 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 particularly suitable for precision soldering, where high demands are placed on solder quality, process stability, and reliability.
SN100C® is a eutectic tin-copper alloy stabilized with nickel and enhanced with 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-containing alloys. The alloy is known for its high process stability and excellent soldering properties in both manual soldering and industrial soldering processes.
The nickel-stabilized structure contributes to stable solder joints, while germanium helps to reduce oxidation and improve the efficiency of the soldering process.
Flux-cored solder wire for fine soldering and precision work
This variant features 2.2% flux and is classified as REL0 according to IPC J-STD-004. The flux supports rapid activation and effective wetting, making it easier to achieve uniform, high-quality solders.
The fine 0.5 mm wire diameter provides maximum control over the amount of solder and makes the product particularly suitable for modern electronics with high component density, small solder points, and sensitive components.
