  • Is there a threshold on ball size where we would not need to re-ball a BGA ( i.e. 8 ball / small type packages).

do you mean you are seeing deviation in ball size prior to placement? if so i don't know of any spec that would cover this. however provided your ball is within 75% of the size of eachother and you are applying solder paste to the pads and not just tacky flux and place/reflow i would think you would be fine.
