I have met solder with Sb as one of element in solder. Could anyone tell me what are cons and pros with such solder ? When and where they suit best.

If your using regular 63/37 Sn/Pb solder there are alot of other metals such as Antimony,Nickel,Iron,Cadmium,Aluminum,Copper,Gold,Bismuth,to name a few. But you need a certain amount of these metals for proper solder composition. Regarding the Antimony,, about .020% is the norm. If you don't have enough, your solder can crumble into white powder after low temp aging,, too much can cause your solder to be brittle. Hope this answers part of your question.
