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 0.032" (0.8mm).
**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.

It is lead-free which is kind of a must for cosumer products these days, and the water soluble flux is awesome. I have PCBs soldered in bulk and I need a fast way to clean the flux off of them, and using water is a lot faster and more convenient than using alcohol in my experience.
First time user of lead-free solder. Right up front, let me say I prefer the leaded solder. This solder is lead free. I requires a little more heating to get that luster. But once heated up, this is probably the best lead free solder you can buy. Very thin wire, which makes it perfect for SMD components. I would recommend you give this one a try.
I've soldered with the leaded stuff for 50 years and was delaying switching to lead-free because of the warnings that it didn't flow well and was generally difficult to use. No way. I found this solder to be just great. The springiness of the stuff feels different, like when you pull a yard or so off the spool and coil it up. This solder flowed fantastically for me though perhaps at a slightly higher temperature. Don't hesitate to use it.
For micro RC aircraft this is not only the BEST solder available.. it's the only solder I know of that works as well. It's lightweight but easy to use like leaded solder and is a better conductor where less solder is desirable to save weight and one gram makes a noticeable difference. Great solder without the problems other unleaded solder suffer from. Thanks Sparkfun for making available... John Hendry^^
Sparkfun's special blend leaves the one other lead-free solder (a random spool bought at Radio Shack - RIP) I've used in the dust! Not sure if it's the Antimony or the lux-Silver, but this alloy melts easier*, is less prone to unintentional bridging and cold joints, reworks like a charm, and doesn't leave as much oxidation on the soldering iron. Flux residue is easy to remove with IPA, haven't tried using deionized H20 yet.
One caveat - at 0.032" this spool is pretty thick (why it gets 4 stars, not 5), so go with the 0.020" spool for general purpose prototyping (it's worth the extra $5) unless you need to solder big wires/connectors.
FYI the soldered connections have a 'frosty' finish, so gotta retrain your eye for what a 'good' connection looks like if you've been using old-school leaded solder.
