I’m currently working on a more complex project that uses double sided assembly (and a weird USB-C connector). To practice these things a little, I ordered some low cost boards to get used to that connector and explore double sided reflow (which seems easier than I expected).

For those who are interested, this is a reference design from framework computer for their expansion card system. It can be programmed with circuitpython or Arduino and utilises a SAMD21 microcontroller.

    I used a Chinese oven that looked just like that, maybe the same model. I found it uneven in its heating, so much so that paste near the door sometimes didn’t flow. It was possibly a step up from my Black and Decker toaster oven.

      Mine is the smallest one of a series of these, it has two heating elements inside.

      I don’t have it for that long but I didn’t have problems so far, I’m usually only making rather small PCBs tho. I did make some recommended modifications like replacing the paper insulation tape with a kapton tape, proper grounding and flashed another firmware.

      I did only use a small hotplate and/or a hotair station, so it seems to be definitely a stepup here 😌.
