If you want to make a kit you'll need some solder. This 1/4 lb (about 110 gram) spool is just the right amount, not too much (like 1 lb spools) and not too little (like those little 'pocket clip' vials). This spool of solder is 0.031" in diameter, with the 'industry standard' SAC305 RoHS lead-free formulation. For flux, it contains a 'no clean' rosin core. Good for all through-hole soldering and some larger SMT soldering (especially when used with wick).

Contains Sn 96.5%, Ag %3.0, Cu %0.5 (96.5/3/0.5).

Perfect for when you need a lead-free alternative to classic 60/40!
