4901
Sn99 No-Clean Solder Wire
4901 is a solder wire for electronics. It uses a
high-purity eutectic Sn99.3/Cu0.7 alloy, with a
no-clean, synthetically refined, splatter-proof
resin flux core. Sn99 solder is a great lead-free
alternative to leaded solders. It is a suitable and
less costly replacement for SAC305.
It achieve a consistent solder and flux percentage
due to our state-of-the-art extrusion wire-drawing
machine, which continuously monitors the wire
to prevent voids and ensure consistency,
