400-NS Series
No-Clean Super Wick
400-NS Series Technical Data Sheet
Description
The 400-NS series No-Clean Super Wick are high quality, precision cleaned desoldering braids that were
produced with up-to-date and environmentally friendly processes and technology. The high purity copper
conducts heat fast, allowing for faster wicking and shorter dwell time that minimizes possible overheating
damages.
Benefits and Features
• Conforms to MIL-F-14256E RMA flux and J-STD-004
• High purity, oxide-free copper
• ESD (Electrostatic Dissipative) safe for 1.5 m [5 ft] bobbins
• Environmentally and PCB safe residues
• Suitable for Use in Food Facilities as a Non-Food Chemical—Canadian and NFS recognition

Storage
Keep away from moisture. Shrink wrapping is recommended for extended storage. Store between
22 and 27 °C [72 and 81 °F] in dry area away from sunlight.
Health, Safety, and Environmental Awareness

handling and other security guidelines.
Braid Desoldering Instructions
Wicking works best for the removal of surface solders. This desoldering method is generally not
recommended for removal of solder in through plated holes. While the use of desoldering (wicking) braids
is not hard, it does require a moderate to advance skill level depending on the project. Novices should
practice on scrap pieces before attempting to an actual repair.
Equipment and Material Needed
• Solder iron equipped with a chisel tip that matches the size of the wick
• Damp sponge
• Scissors
• (Optional) flux—like the MG 8341 No Clean Flux Paste
• (Optional) cleaners—like the MG 4140 Flux Remover or 413B Heavy Duty Flux Removers
Preparation Steps
• Remove conformal coating that may be present.
• Clean residues/oxides that are present using a flux remover.
• For lead-free solder, start with tip temperature of about 315 °C and adjust as necessary.
• Choose a braid that matches the size of the solder to be removed. If there are small beads,
choosing a wider braid will also speed up the desoldering process.
To Remove Surface Solder
1. Heat up the soldering iron.
2. (Optional) Apply flux to the lead or land area.
3. Set the braid on the solder to be removed.
4. Place the solder tip on the braid, avoiding contact with other
components.
5. When wicking action has ceased, remove the soldering iron and
braid together in perpendicular motion from the surface.
6. Let the area cool, clean the tip with the sponge, and repeat
removal steps as necessary.
7. Clean flux residue that may have accumulated.
TRICKS: When the solder bead to be removed is very thin, adding a little bit of solder to the joint prior
to the removal attempt can help.
TRICKS: Cutting an oversized braid at an angle with scissors can help with desoldering small areas.
ATTENTION: Do NOT let
braid solidify on the joint.
TIP! To avoid “drag
whiskers”, do not move the
wick along the surface during
desoldering.
TIP! Be careful not to
overheat
