I am quite new to smd soldering with solder paste.
I needed to solder some sensors with QFN package, so it was not possible to
use normal soldering iron.
I am using an average kitchen hotplate, with no regulation and supervise everything
manually with the temperature sensor of a multimeter.
All this is rather approximate, but I used
low melting point solder paste (Alloy: SN42 + Bi58) with 138 C melting point.

All this seems quite nice, and I wonder if there is any drawback at using this
low melting point solder paste vs normal one ? Any advices ?
Thanks
