I am designing a BGA placement and need to get the via's out away from the part. What is the smallest via diameter I could use?

The minimum via hole size used will have a significant effect on the cost of the board as it limits the number of PCBs that can be drilled as a stack. Not withstanding the radio performance implications of small diameter via holes, typical minimum sizes of 0.25 mm are commonly used. A reduced cost will be achieved if the minimum hole diameter of 0.5 mm can be used. Quoted from: http://www.plextek.com/papers/gspcbdes.pdf
