TL;DR it is possible by hand
HOW TO
Here is my first try soldering 0.15mm (0,0059") wire to a TMP112 sensor. These come in an SOT-563 package with 0.5mm pitch.
I made a cutout in a piece of cardboard, glued it to a piece of aluminum (we know it's aluminium, right?) and tried soldering wires to it. Worked OK, though I had to use a really fine tip for that. Took me around 10 minutes.
The main problem is, the wire lengthens a bit while soldering, so it easily slides off the pad. Should I need to solder a few of them I need to add a weight or spring to one side which compensates for that.
After cleaning a bit, this is what I ended up with:
Of course opposite pins are still connected to each other, but that will be corrected when doing my next tests with a better setup. I think I know how this will work much better...
BTW: Cutting the leads in between with a side-cutter didn't work well (topmost contacts), using a cutter knife does a good job though:

Heh, nice technique cutting away the surplus wires. :-) Good one.
Are you sure? yes | no
Thanks! Going to build a jig so I do not have to cut them
like this. It's kind of much force on the sensor to use a razor blade for that...
Are you sure? yes | no
I work with a No.11 scalpel for everything, it has a needle tip and doesnt tin so you can hold wires down and solder them.
I also use the round ones sometimes. These can be turned into a saw by scraping sideways just once across a bit of oxide sandpaper... You dont want to blunt it, just take nicks out of it...
You can also glue the wires temporarily to the device with a blob of nail varnish or superglue, cut through that and then wash the cutouts and glue away with acetone. ;-)
Jigs are great, but as painful to make as soldering the device IMO. I like your technique, if I can get away with a procedure over hardware I will lol, its kind of like programming.
Good luck! :-)

nice!!
