4890–4898 Sn60/Pb40 RA Solder Wire is electronics grade solder wire. The 60/40 rosin core solder uses a classic tin-to-lead alloy ratio complemented by a RA-like flux core. This solder wire meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications. It melts at slightly higher temperatures and over a wider temperature range than 63/37 solder. This results in robust and reliable joints that are highly resistant to whisker formation.
These 60/40 leaded 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, resulting in a top-grade solder wire.
