Lead Free Super Wick 400-LF Series Technical Data Sheet 400-LF Series Description The 400-LF series Lead Free 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 RoHS High purity, oxide-free copper REACH compliant 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 ChemicalCanadian and NFS recognition letters available on request Desoldering Braid Selection Guide Cat No. Width Length ESD Safe Spools Label Color Code in mm ft m anti-static 424-LF 0.06 1.5 5 1.5 Yes YELLOW 425-LF 0.08 2.0 5 1.5 Yes GREEN 426-LF 0.10 2.5 5 1.5 Yes BLUE Flux Properties High temperature, mildly activated rosin flux. Physical Properties Method Value Flux Classification Conforms to MIL-F-14256F R (Rosin) J-STD-004 ROL0 Flux Percentage <5% Corrosion JIS Z 3197 and QQ-SS-571d Non-corrosive residue Cleaning Requirements Optional Compatibility Chemical the flux residue from the Super Wick is inert under normal conditions. The flux residue can be cleaned with a flux cleaner like the MG 4140 or 413B. 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 and Safety: The Lead Free Super Wick may cause allergic reactions in some individuals. Avoid breathing fumes produced during desoldering. Other than possible allergic reactions, the flux residue presents no known health or environmental hazard. HMIS RATING NFPA 704 CODES HEALTH: * 1 0 FLAMMABILITY: 0 1 0 PHYSICAL HAZARD: 0 PERSONAL PROTECTION: Approximate HMIS and NFPA Risk Ratings Legend: 0 (Low or none) 1 (Slight) 2 (Moderate) 3 (Serious) 4 (Severe) 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) cleanerslike 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.
