Hello Everyone;
I need soldering wire with low Liquidus temperature (about 120°C). Can anyone help me? Please introduce me any choice.

Tin/Lead  Melting Point 
40/60  460 degrees F (230 degrees C) 
50/50 418 degrees F  (214 degrees C) 
60/40 374 degrees F  (190 degrees C) 
63/37 364 degrees F  (183 degrees C) 
95/5 434 degrees F  (224 degrees C)

You can't go lower than that ..

What's about Bismuth's alloys or Indium alloys?

Try to combine lead free solder containing bismuth with solder containing lead and there is a possibility for the solder to reflow at reduced temperature (around or less than 100°C) ..
