Description: This is 50g of high quality, Lead-Free Solder Paste, the perfect amount to keep around for prototyping and hobby projects that require a bit of SMD soldering. Solder Paste Stenciling is the easiest and quickest way to solder some of the trickier SMD components. Here at SparkFun, we use solder paste stenciling on pretty much all of our boards. It saves us a lot of time. But stenciling takes more than just a stencil and a dream… you’re going to need some paste.
The composition of this paste is Sn: 96.5%, Ag: 3%, Cu: .5%
Note: Although this Solder Paste comes in 100g containers, it contains 50g of paste. The container is not intended to be full.

I’ve been prototyping my own PCBs for nearly a decade now. Lately I’ve been getting all bent out of shape as components get smaller and smaller, but I can’t figure out how to use them because the packages hide the pins (QFN, BGA, MLP, MicroFET..).
I’d spent a lot of time making footprints larger than the packages so that I could solder one pin, and then wick the rest. But this was a mess, and often didn’t work on the first try (which means it only gets worse from there).
And then I got a stencil and tried this stuff. It’s just completely magical. You smear it all over the design the table top and maybe some on the dog, but when you apply heat the surface tension just draws it back onto the pads (as long as you don’t have too much it works fantastic).
I watched the video, and bought a little $15 hot plate. That works great but I’m not sure I needed it. I’ve also tried the hot-air-gun approach and I actually like it better because it offers a bit more control. The hot plate has a lot of thermal capacitance that gets carried away, and makes things a little more complicated to control. The paste is tacky enough that parts don’t just blow all over the place if you’re conservative with the airflow. Also the hot air gun seems to make more sense for 2 sided designs (which is sort of a necessity with two layer boards)
50g seems like it should last a lifetime, but we’ll see how long it keeps in the fridge.
Anyhow, Good job sparkfun: you rock. Making my life easier, keep it up. I like that.
PS The dog was meant to be hyperbole. Don’t do that.
