I’m a few months late, but I actually recommend people try to solder these at home at a hobbyist.
Below a certain size, you rely upon surface tension of the solder to “pull” the components into place. Its a combination of solder-mask (by your PCB-manufacturer) + well calibrated PCB Software + proper heating technique (hotplate and/or oven).
You’ll be surprised how “far” lead will pull your components into the correct spot. In fact, the force is so powerful that smaller components can tombstone if one side melts before the other side (ex: cold joint due to more copper pour melts slightly after, causing the “hot” side to YANK the component so hard it “flips up”).
VQFN packages are “square” though, so its unlikely for them to tombstone.
That looks like a real pain in the ass to solder with a 0.35mm pin pitch.
Not something I would try to hand-solder. Not something that feels relevant for me as a hobbyist either, although it’s very cool.

Imagine the arduino-clone boards with these… For very small hands!
