MG Chemicals Sn99 Lead-Free solder 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. This solder meets J-STD-004 and exceeds J-STD-006 specifications. It is a great lead-free alternative to leaded solders. It is a suitable, less costly replacement for SAC305. It leaves a small amount of post-soldering residues that is non-conductive and non-corrosive and won’t cause electrical shorts. The name no clean refers to the fact that the flux residues are not harmful to assemblies and does not mean there will be no residues.
