The 4890–4898 Sn60/Pb40 RA Solder Wire is an electronic grade solder wire. It uses a classical tin-to-lead alloy ratio, which is complemented with a RA-like flux core. The solder wires meet J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications. It melts at a slightly higher temperature and over a wider range than the 63/37 solder. It results in robust and reliable joints that are highly resistant to whisker formation.

The 489x leaded 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.
