Having discovered Benjamin Vedder’s open source ESC ( http://vedder.se/2015/01/vesc-open-source-esc/ ), I’ve decided to build a couple over the summer. I ordered parts a while back, and after exams I finally have enough time to build it. So I wandered into the TAFE side of school to borrow a reflow oven from the techs. I’ve done a number of fiddly things in my time, but this was by far the fiddliest. Tiny things everywhere. This was my first time with reflow, and first time with stencils for the paste. Again, fiddly, but once the stencil is centred, so much less fiddly than other methods. I will get metal stencils next time, I think, but the mylar was ok for this job.
All present and correct on side 1. Didn’t get around to side 2 on Monday, but I did arrange a lot of tiny resistors.
