No-Clean Super Wick 400-NS Series Technical Data Sheet 400-NS Series 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 ENVIRONMENT * High purity, oxide-free copper * ESD (Electrostatic Dissipative) safe for 1.5 m [5 ft] bobbins RoHS REACH compliant * Environmentally and PCB safe residues * Suitable for Use in Food Facilities as a Non-Food Chemical--Canadian and NFS recognition letters available on request Desoldering Braid Selection Guide Cat No. 424-NS 424-NS-10 a) 425-NS 425-NS-10 a) 453-NS 426-NS 454-NS a) Packs of 10 Width in mm 0.06 0.06 0.08 0.08 0.08 0.10 0.10 1.5 1.5 2.0 2.0 2.0 2.5 2.5 Length ft 5 5 5 5 49 5 49 m 1.5 1.5 1.5 1.5 15.0 1.5 15.0 ESD Safe Spools anti-static Label Color Code Yes Yes Yes Yes No Yes No YELLOW YELLOW GREEN GREEN GREEN BLUE BLUE Flux Properties High temperature, mildly activated rosin flux.

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 Please see the 400-NS Series Safety Data Sheet (SDS) for more details on transportation, storage, 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. 2. 3. 4. Heat up the soldering iron. (Optional) Apply flux to the lead or land area. Set the braid on the solder to be removed. 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. 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 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.
