If you want to make a kit you'll need some solder. This 0.1 lb (about 50 grams) spool is a good amount, not too much (like 1 lb spools) and not too little (like those little 'pocket clip' vials).
This is lead-free solder, so great for lead-free shops, however it's not SAC305, a formulation which some people prefer. For flux, it contains a 'no clean' rosin core. It's good for all through-hole soldering and great for any kind of SMT soldering.
Contains Sn 99.3%, Cu 0.7% with a flux of 2.2%.Perfect for when you need a lead-free alternative to classic 60/40!
