Hey John,
Can you build your robot to do the soldering on your 12 Circuit Boards ?
(There is that mass production CREEPING UP again !!)

It's possible the AR4 with the enhanced drive might be able to do that. Many years ago for my JGRO CNC router I bought a solder paste dispenser. The idea was to place the circuit board into position and have the G-Code push some paste onto each pad. Then, one could either use tweezers or add the whole pick and place mechanism along with camera to correctly orient the parts. Lot's of kits or plans out there for that sort of thing.

However, twelve boards aren't a lot of boards for all the work. And the solder paste flux has a pretty crappy life so one has to be prepared to do lots again. But I think if the robot arm can position close enough to put the say 0603 parts in place and also line up the pins on a QFP device so the hot air oven just lets them slide into place. It's the surface tension that does that. Really cool to watch.
