Chemtronics 50-4-100 Soldering Braid .110" 100ft

SKU CH-49H4-NP36T

Extra-fine copper braid with non-activated rosin flux removes solder from large pads in a 100 ft roll

  • Extra-fine copper braid absorbs molten solder quickly
  • Non-activated rosin flux leaves no corrosive residue
  • Meets MIL-F-14256F type R flux standard
  • 100 ft length covers many rework tasks
  • .110 in width suits large pad desoldering

Desoldering braid for large pads

Chemtronics 50-4-100 is a pure copper wicking braid designed to absorb molten solder from large pads. The extra-fine blue braid measures .110 inches wide and comes on a 100 ft spool. It suits technicians who need reliable solder removal in through-hole or high-mass joints.

Rosin flux coating leaves no corrosive residue

The wick is coated with non-activated white rosin flux that meets MIL-F-14256F type R standards. This flux activates during heating to promote fast solder uptake and remains inert after cooling. RoHS compliance confirms the materials meet restricted-substance requirements for electronics work.

100 ft length gives extended rework capacity

A single spool supports many desoldering sessions on large pads before replacement. The braid is not compatible with lead-free solder alloys, so users working with lead-free processes must select a different flux formulation. Width is fixed at .110 inches and cannot be changed for finer pitch work.

Questions about this item

How often will I need to replace the 100 ft roll of .110" braid?

The 100 ft length provides a long supply; each section is used once and discarded after absorbing solder, so replacement depends on your desoldering volume.

What limits continuous use when working on large pads?

The flux coating meets MIL-F-14256F type R and leaves no corrosive residue, so the practical limit is the speed at which you can feed fresh braid onto the joint.

Does the rosin flux produce noticeable fumes or heat during all-day use?

The non-activated white rosin flux generates typical soldering fumes; the fine copper braid conducts heat away quickly, keeping the work area cooler during extended sessions.
