I'd like some opinions on capacitor placement for BGAs.

Where are you placing the filter caps; top or bottom (we're using 0508 and
0603)
If on the top, how far away are you placing them. (we're using a .150
keepout for rework) and are they helping
What problems do the rework guys have with the caps on the bottom

Any insights/thoughts on this subject would be appreciated
There seems little, middle ground on this issue for engineering and mfg.
