We have also discussed an open source pick and place machine capable of 
.005mm accuracy that can handle very accurate placement of BGA's. 
Linuxcnc can already handle all the control and the XYZ stage is pretty 
simple for small board like these. It's something that could easily be 
built DIY for $1-2K depending on the size and travel.
