Hi! Augustin here, one of the presenters of the talk: Alex actually built a vapour phase soldering oven from scratch a few years ago! Indeed they are not exactly practical for series production, though they are amazing for small runs of very challenging to solder board though.
Main issues is solvent recovery: as another commenter pointed out, Galden is very expensive, and it is also extremely greenhouse inducing and we were not confident in our ability to recover it completely, especially at "scale" (100 boards per month or so).
In our case, we picked a hot-air convection oven, which, while not as good as VPS, is still a lot better than IR at not burning components. Our main challenge is always space, so we went for a production batch oven which already has more throughput than we need for us to get to profitability.
The plan is to upgrade to a long and big conveyor oven once we move to a bigger facility, these are quite cheap and they are compatible with a fully automated production line.
Ngl, everything on crowd supply is overpriced. I bought an sdr through them several months ago, and the antenna I bought with it could be found on mouser for at least $10 cheaper.
Well the "source" is arguable. If you want stock parts it's definitely Mouser (or their suppliers) but if you want a project, namely something new made out of parts provided by Mouser then it's still CrowdSupply. I didn't take the time to compare but I imagine prices are roughly comparable and maybe you get projects slightly faster on CS, I'd hope so at least. You definitely get to follow the evolution of the project though, which is positive (your learn how it goes) and negative (you can get frustrated by delays).
