MG Chemicals - 4901-112G Sn99 No Clean Lead Free Solder, 0.032" Diameter, 1/4 lb Spool;

Sn99 No Clean Solder Wire is an electronic grade solder wire. It uses a high-purity, eutectic Sn99.3/Cu0.7 alloy, which is complemented with a no clean, synthetically refined, splatter-proof resin flux core. The 4901 solder meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications. This solder is a great lead-free alternative to leaded solders. It is suitable, less costly replacement for SAC305. The 4901 solders achieve a consistent solder and flux percentage through a state-of-the-art, extrusion, wire-drawing machine. This machine continually monitors the wire to prevent voids and ensure consistency, providing a top-grade solder wire.
