The 4933–4935 Sn100e Lead Free No Clean Solder is an electronic grade solder wire. It uses a highpurity, eutectic tin/copper/cobalt alloy that is complemented with a no clean, synthetically refined, splatter-proof, resin flux core. The 4933–4935 solder meets J-STD-004 and exceeds J-STD-006 specifications.
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 493x forms brighter, shinier, and less grainy joints. Furthermore, it is less expensive than SAC305.
The 4933–4935 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.
