This Sn63/Pb37 RA Solder Wire is an electronic grade solder wire. It uses the eutectic 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 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.

The 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.

  • Eutectic alloy (liquidus = solidus temperature)
  • Alloy exceeds J-STD-006C and meets ASTM B 32 purity requirements
  • Flux meets J-STD-004B
  • Rosin-activated flux
  • Fast wetting
  • Fast flowing
  • Non-corrosive residue
  • Non-conductive residue

Contains 227g of 0.040" diameter wire (1/2 lb.)

Rotorgeeks Comment
This is the stuff you want - 63/37 is eutectic, meaning there is no transition phase between solid and liquid where the solder is in a 'plastic' phase and any motion on the wires can intefere with a good solder joint.  We've had some bad experiences with China sourced solder and only use this brand in all of our builds.
