A bit of a ghetto reflow solder setup but 20€ for the entire thing is a really good price. (The controller on the left side costs 250€ new!)

@sad_electronics does it have additional heating elements? or just the factory default? (I found ours struggles to follow the temp ramp-up curve with just the standard 800-W (?) heater)

@sad_electronics yep, and now I’m looking at adding a few extra heating elements because it’s not quite fast enough to do SAC305 within the reflow profile. It gets there eventually but that’s not great for the PCB or the components.

@sad_electronics @uint8_t I have a similar setup that struggled a little but covering most of the glass front with reflective foil and closing a few gaps around the front door fixed that

@oseiler @sad_electronics I added glass wool insulation between the oven shell and the housing sheet metal and it still failed to match the reflow curves provided by the component manufacturers

@sad_electronics @uint8_t 🙁

I'm not getting perfect curves but the result is usually close enough and totally fine and certainly beats my little hot plate. It might be more than 800W though

@sad_electronics @uint8_t

@oseiler @sad_electronics oh this looks nice. I think ours isn’t too far off from the curve you’re showing. I baked PCBs that had both very small and very large thermal mass components on it and had to do a second cycle. But it’s certainly a lot better than the infrared ovens (had one of those earlier)

@sad_electronics @uint8_t I've placed the thermo couple right under the pcbs, floating on a little wire if that makes a difference? Also using paste with low-ish melt point helps. Still figuring stuff out tbh...

@sad_electronics @uint8_t forgot to check my small oven - it claims to have 1200W
