4901 - Sn99 No Clean Solder Wire

4901 Sn99 No Clean Solder Wire is a solder wire for electronics. It uses a high-purity eutectic Sn99.3/Cu0.7 alloy, complemented with a no clean, synthetically refined, splatter-proof resin flux core. 4901 solder meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications.

Sn99 solder is a great lead-free alternative to leaded solders, and is considered one of the best solder wires for electronics. It is a suitable and less costly replacement for SAC305.

4901 lead-free solders achieve 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.

Visit 4900 for a no clean SAC305 solder wire and 49500WS for a water soluble Sn100e solder wire.

For also offer Sn60/Pb40 leaded solder wires (no clean and RA flux core) and Sn63/Pb37 leaded solder (no clean and RA-like flux core).
