One shift register down, one to go. No electrical tests yet, but all sixteen leads move with the chip when I give it a nudge. Wire is from a 28 AWG stranded bundle, which turns out to be 7x36.
More to come..
A project log for blinktronicator
Sixteen different LED colors on a teeny tiny board.

You could tombstone the part and solder it on the PCB on one side. i.e. chip standing up at 90 degrees and solder fillet between PCB & the vertical pads. That would give you some mechanical support and 6 less wires to worry about.

That's a great idea, actually. The hardest leads to land were the first ones because the chip wasn't secured. I've still got four boards left that are otherwise worthless, so I might give that a try.

Thanks! Yeah, it happens--that's what I get for rushing through the whole process, I suppose. 3 ICs is three times the number I've done before on a PCB design--I can't imagine what I'd mess up with a more complicated circuit. Hah!

You're crazy.

I'm impressed, did you have a microscope? the dead bug is really cool looking BTW. Cover in some clear epoxy or something to show it off.
Are you sure? yes | no
Thanks! I'm using a big 3x ring magnifier; might be time to get my hands on a microscope. I'll definitely encase it in epoxy if it works.
Are you sure? yes | no
Hot glue is actually the answer here, too, tbh
Are you sure? yes | no
Next time I'll definitely take your advice.. getting the damn chip to stay put while I got the first few wires secured was a PITA.
Are you sure? yes | no
Glad you went with the tedium, I wanna see it workin'! That looks like some bad-ass deadbugging, too.
