Over on the mPrinter blog, they have a rundown of their experiences reflowing surface mounted components while prototyping the mPrinter.
While building the mPrinter, we’ve assembled a lot of prototypes. While it’s certainly possible to solder 0402 and 0603 surface mount components by hand, it’s not a lot of fun. If you don’t want to hand solder, there are two main ways to do small-scale reflow: an oven or a hot air rework station. We went with a small oven, and this post goes over a bit of the experiences we had.
Once you are done on the mPrinter blog, be sure to check out our detailed tutorials on all things SMT manufacturing on the Adafruit Learning System!
