interesting. Do you use an ordinary kitchen hotplate?

No, it's made for SMD, it's the same than this one but another brand (and color, much better looking in white :D ). I was looking on AliExpress but saw a local shop was selling some. Cheaper than AliExpress and only 2$ for 48h delivery to my doorstep :)
It's much better than a kitchen hotplate as temperature is relatively accurate and doesn't seem to vary too much between centre and periphery thanks to the thickness of the metal plate. The only problem is at the end, it's extremely slow to cool down and it's easy to burn yourself on the unprotected plate. Body also gets pretty hot after some time so I need to put it on a silicon soldering mat to protect my desk.
Result of the first manual test is good enough, I'll test next week with stencil-applied solder paste if DHL is not messing too much with the customs. -
So I gave it a try today with a solder paste syringe from AliExpress (not perempted like the paste I got from my local shop before). I used a normal syringe pusher (after removing the rubber end) and it went relatively smoothly with a green colored needle (don't know the diameter). I guess I'll try the small syringe technique as it must be easier to have regular flow, but it was good enough.
Without much training I managed to solder my ESP32 module (and 2 buttons) to the adapter board. I used my small 10*10cm hotplate, remotely following the reflow profile for this solder type and all connections are good.@nca78 said in SMD Reflow Oven / PID:

To approximate the reflow profile, did you manually adjust the temperatures by hand while looking at a clock or something?

Yes. That's why I say "remotely" :)
Not very convenient but still much faster than soldering all the pads by hand.
