Questions
How big is the Reflow PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Reflow use?
95 parts, built around the BT139X-600,127, IRM-03-5S, MOC3023M and 74ACT04MTC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Reflow KiCad files?
From the windsorschmidt/reflow repository on GitHub, at the commit this page was made from: the board is pcb/reflow.kicad_pcb and its schematic pcb/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reflow design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
