I went and looked up some typical quotes from Screaming Circuits.. we're
typically doing a 4-20 boards, and to place <100 parts runs us about
$20-50 per board (if I had to guess about their "setup vs each" pricing
based on the different volumes I had quoted for the same board, I'd say
setup is in the $250-300 range, and assy is in the $15-20/board range.
Not everything on these boards is machine placeable, and there's some
hand assembly required (like soldering pins into a carrier, and then
soldering the carrier onto the board). There's also some shielding cans
that may or may not be machine placed and soldered.
