Ofer,
It says in my spec:
"In order to enable rework to any BGA device without affecting the quality of
neighbouring component joints, a component exclusion zone of 5mm is required
around all BGA sites.
Exceptions to this are passive devices, which if essential may be sited as
close as 2mm to the device. In the event of rework, these devices would have
to be removed prior to BGA removal and resited after BGA replacement."
Hope this helps,
