4900 SAC305 No-Clean Solder Wire is electronics grade solder wire. This lead-free solder uses the predominant lead-free alloy composition, exceeds J-STD-006C and meets ASTM B 32 purity specifications. It is complemented with a no-clean, synthetically refined, spatter-proof resin flux core that is classified as REL0 according to J-STD-004B. This solder is a great alternative to leaded solders.

SAC305 lead-free solder achieves a consistent solder and flux percentage thanks to our state-of-the-art extrusion wire-drawing machine, which continuously monitors the wire to prevent voids and ensure consistency, providing a top-grade solder wire.
