Imre, I just use a standard adjustable temp. Weller soldering iron with an 0.032" tip, the smallest size they sell. I bought some syringes with paste solder and paste flux. These work a lot better for surface mount than wire solder. However, the old trick of laying a piece of wire solder alongside a row of pins, and then melting it all at once still works too. As long as you have enough flux, anyway. I have several pairs of tweezers with different tips, never could get those vacuum tweezers to work right. This is a relatively slow way to do surface mount, but for occasional use it works fine. I never got the toaster oven method working very well. -- Lawrence Lile "dr.

However, in the catalogue of Farnell what I found soldering irons with tips which seem to be appropriate for the said parts are called as desoldering/reworking tools. My question is: are these nice things not capable to solder SMT parts at all? If really not, how could I do the job? Any help is greatly appreciated.
