The 4942–4944 Sn100e RA Solder Wire is an electronic grade solder wire. It uses a high-purity, eutectic tin/copper/cobalt alloy that exceeds J-STD-006C and meets ASTM B 32 purity specifications. It is complemented with a rosin activated, medium activity flux that is classified as ROM1 according to J-STD-004B. This solder is a great lead-free alternative to leaded solders. It generally provides better wetting, contact angle, flow, and visual appearance than typical Sn63/Pb37 no clean solders, while still delivering excellent performance characteristics. It offers superior solder penetration into plated through holes and surface mount interconnects. Further, it is a suitable replacement for SAC305 solder since the 494x forms brighter, shinier, and less grainy joints. Furthermore, it is less expensive than SAC305. The 4942–4944 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.
