BGA Placement Pass Rate ?

Hi, Does anyone know what the placement success percentage is for lead components And the placement success percentage for lead free BGA components. We place many varieties of BGA devices, over 100 different size parts, from 1000 pin BGA to small 4mm square DFN's

Any info would be helpful or where I can ask next, there seems to be no industry standard pass percentage for BGA placements.
