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.
We wanted 50g of unleaded solder paste, as the perfect amount to keep around for prototyping and hobby projects. Unfortunately, though these small tubs are labelled as 50g, they actually weigh in at closer to 40g, so only almost the perfect amount.
The composition of this paste is Sn:90%, Ag:3%, Cu:7%
Check out the Solder Paste Stenciling tutorial (and the video below), if you haven't already.
Note: These tubs are labeled as 50g but lately we've measured closer to 30g of solder paste in each container.
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: Experienced - You might be required to do some reflow or basic rework with SMD components. A heat gun, Heaterizer or other tools might be required, and a good understanding of SMD soldering as well as PTH soldering are required.
