4880-4888 - Sn63/Pb37 RA Solder Wire

The 4880–4888 Sn63/Pb37 RA Solder Wires are an electronic grade solder wires. This 63 37 solder uses the eutectic tin-to-lead alloy ratio, which is complemented with a RA-like flux core. The tin lead solder wires meet J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications. The is one of the easiest solders to work with because it offers a low-melting temperature with a sharp melting/solidification point, which results in robust and reliable joints that are highly resistant to whisker formation.

This 63 37 rosin core solder achieves 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, providing a top-grade solder wire.

For Sn63/Pb37 no clean solder wires visit 4860-4867. We also offer Sn60/Pb40 no clean solder wires and Sn60/Pb40 RA Solder wires.

For lead free solder wires visit 4900-4917, 4901, and 49500WS.
