Desolder - Braid More information and a detailed price comparison of desoldering braids on www.desolder.com Unmet in Low, User-friendly Price Levels 3S-Wick / Desolder braid based on Spirig patents 4,416,408 (after intervention of a competing brand unchanged re-issued by the US Patent Office under Re. 32,086). Further USA patents 4,081,575 / 4,133,291/ 4,227,415 / 4,323,631 / 4,164,606 / 4,078,714. 3S-Wick / Desolder braid is manufactured under a Spirig patented process termed . Vacuumisation has when compared with conventional hot air drying technology several advantages over other makes. Excellent shelf-life and desolder speed are the result of this advanced, patented technology. 3S-Wick / Desolder braid has now been used for almost 30 years worldwide and an estimated over 1 billion desoldering joints have been successfully performed during that time span. 3S-Wick / Desolder braid has compared to standard "hotair" dried wicks a high solder absorption rate and can be nicely demonstrated using the MIL-STD-202E Method 208C Solderability Comparison test. The speedier the solder pick-up is performed by the wick, the less heat energy will be injected into the desoldered area. Physics & chemistry clearly teach: “the lower the temperature and the less time is involved the less will be the potential reliability degradation of any system". 3S-Wick / Desolder braid also has an over the years perfected and optimized balance between thermal mass related to its wick braided volume. Too low a thermal mass of the wick would allow the temperature on the joint to instantaneously jump to the solder melting temperature levels. Again, a too steep temperature ramp-up will create higher stress on the joints. ATTENTION and CAUTION: Using so called wicks, especially on repeated soldering operations at the same location, might cause de-laminations. 3S-Wick / Desolder braid are only available from Spirig Switzerland. Regularly "me-too" wicks appear on the markets and leaving a corrosion trace behind do disappear again. 3S-Wick / Desolder braid is easy used and controlled. Depending on to-be-removed solder volume selection of the correct Wick size is made. Size <00> for very fine, for small, for medium and for the larger sized desolder tasks. 3S-Wick / Desolder braid application Gently press end of wick with hot soldering iron tip onto the to be desoldered area or joint. The solder must be molten by the heat transferred from tip through wick into solder. The temperature rise at desoldered area will be dampened by the thermal mass of the wick. There is no immediate jump from room temp to those 240°C solder alloy melting points. As the solder alloy melts it will be absorbed by capillary forces into the wick / braid interstices. The desolder operation is done. The solder saturated wick end is cut-off and a new fresh, not used wick end is available for the next desoldering operation. 15 / 20 / 25 mtr spools Lead free solder alloys will demand even more caution by the user or an "automatic" protection by the balanced mass wick material. 3S-Wick / Desolder braid uses an elctronic-safe special formulated flux. The flux falls into the DIN EN 29 454 1.1.3 (previous DIN8511 norm flux group FS-W-32). The minimal flux residues can be left (no-clean) on desoldered area to protect solderability there. The minimal flux residues left after the desolder operation on the area is designed to act and work there as a solderability protecting layer. Preservation of solderability after a soldering or de-soldering process is a major concern in repair or touch-up of electronic assemblies, be it pc board pads or component leads.
