  • My solder paste is standard leaded stuff (Sn63/Pb37). Only thing I'd say is it'd a million times easier to use in a syringe if everything is warm (25 degrees C or more?). If it's not, the paste is hard to push out, and it often doesn't stick to the board very well.

    I use a cheap temperature controlled hot air gun from eBay, set on lowest fan speed at about 230 degrees C. Seems to work pretty well - especially as most stuff I work on (like the Pico boards) has quite a small area.
