Is that placement side only or through the board? What about micro BGAs?
Just started placing a new design with a 176 ball .8mm pitch BGA and was
about to ask the same question?

        I've been using .200 in. as a minimum around all BGA's.
        Until mfg. lets me know otherwise. It also gives enough room for
inspection.
