We don’t want to hype this solder TOO much, but this could possibly be the best solder in the world. There, we’ve said it. This is a special blend made specifically for us and we love it. It all started as a quest to find the best solder to use in our production process and ended up being the best we’ve tried. The best part is that it’s lead free and has a water-soluble flux core.
This package contains 1/4lb of solder and has a diameter of 0.020" (0.5mm).
Mix: 96.35% Sn (Tin), 3.0% Ag (Silver), 0.5% Cu (Copper), 0.15% Sb (Antimony).
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

This solder melts easily, but holds a firm grip. Even with mediocre soldeing skills, some of my classmates' cold joints made using this solder have held in mechanical connections. Yet, it is still very workable and flows with ease compared to a 60/40 solder I used to use.

I highly recommend this solder. It is the easiest melting, best flowing lead free solder that I have ever used. I especially like the 0.020" diameter, which makes flow control much easier. I used to introduce my students to soldering with 60/40 lead and felt bad about starting them out on the wrong environmental “foot”. We regularly use this solder now with no more beginner’s problems than we had with lead. I have also been able to use a cooler iron with this solder. (I have to be honest - any soldering has beginners' issues. Our students regularly burn the tips of their soldering irons. This solder’s flux also scorches, but I’m not sure it is any more prone to this than any other.) Buy it!
Fantastic solder, I think it’s the best I’ve ever used, the thickness(0.5mm) is perfect and it’s so easy to use, it melts and flows easily, highly recommend. I’ve heard some bad things about lead-free solder, but this one is just AMAZING! I got it right the first time I used it, I think it will be a great option for starters, and for any one actually.
This is excellent lead free solder, but I wish Sparkfun would also sell a smaller diameter version. When working on small pitch parts, I find it’s hard to limit the amount of solder deposited. I’d love 0.010" and 0.015" diameter versions of this solder.
not sure what else there is to say. flows pretty good for a lead-free solder.

… it’s still cumbersome to solder with it (for beginners, especially) as it doesn’t flow with the same ease as tin-lead alloys.
