Hello juliorz > I am currently using a Fluxing agent made by GC electronics part # > 10-200 > “Solder Flux” >
I am using here solder S-Sn60Pb40 1mm and 0,5mm from "Felder". Also the desoldering wire "Entlötlitze 2mm No. 27162000" from "Felder. I also used wick and swissstone. All the same, if it is not too old. And, and of course, i use a pump, if the situation is not too cramped. As fluxing agent homemade from colophony/isopropanol or pure stearine, as mentioned before. You can also made very good desoldering wire from colophony/isopropanol mixture soakening the shilding mesh of RG58 or RG213 or similar coaxial wiring. I also often soake the desoldering wire with this colophony/isopropanol mixture, to get better results. Another issue about lead free solder and the gap between component lead and hole: The capillary attraction for lead free solder ist much less than for leaded solder. So the gap also has to be smaller.....annother reason to make narrow holes at production. But bad for rework. with best regards: Bernd Wiebus alias dl1eic -- GMX DSL: Internet, Telefon und Entertainment für nur 19,99 EUR/mtl.! http://portal.gmx.net/de/go/dsl02
