Ellsworth,

We found during a recent BGA evaluation project that BGA placement with the 
FIP2 is not possible from the Matrix Tray Unit (MTU) and Fuji does not 
provide a solution.  You can dispense BGAs from tape and/or stick feeders.  
However there is problem with placement accuracy since the machine is not 
capable of viewing the bottom of the component in normal operation (binary 
backlit vision) and must use the silhouette of the component for placement 
alignment.

Fuji solved the problem with the FIP3, it has a restraining arm on the MTU 
shuttle for BGA handling from the MTU.  It also uses gray scale front lit 
vision which allows placement accurately from the bottom side (ball) view.
