TechSpray No-Clean Blue #4 Braid
This desoldering braid uses a no-clean flux coating classified REL0. It meets IPC J-STD-004 and NASA NHB 5300 4 (34-1) standards. The lead-free wick produces clear, non-reactive residues that will not leave ionic contamination or cause dendrite failure. It is suited for technicians who need reliable flux removal without a separate cleaning step.
Upgrades from standard flux-coated wick
Standard braids often leave residues that require post-solder cleaning with solvents. This no-clean formulation eliminates that step while meeting MIL-F-14256 and NASA NPC 200-4 requirements. The jump is worth it for high-reliability work where ionic contamination must be avoided and cleaning time is limited. It replaces wicks that leave visible flux or require aggressive cleaning.
Check spool length and braid width before ordering
The spool provides 5 ft of braid at a 0.098 in width designated as size #4. Verify that this length covers your typical rework volume and that the width fits the pads and components you service. The bobbin is ESD-safe for static-sensitive environments. Buyers needing wider braid for large joints or longer continuous lengths for high-volume production should look elsewhere.

Questions about this item
What width and length is the #4 desoldering braid on the ESD-safe bobbin?
The #4 braid is 0.098 in wide and comes on a 5 ft spool wound on an ESD-safe bobbin.
How do you apply the no-clean flux coating without leaving ionic residue that could cause dendrite failure?
Heat the joint with the braid on top; the no-clean flux activates, wicks solder cleanly, and leaves clear, non-reactive residue that requires no cleaning.
When should the spool be replaced if the flux coating degrades over time?
Replace the spool when the braid no longer wets quickly or leaves dark, sticky residue, indicating the no-clean flux has lost activity.
