sree, There is no Definite. You have to make the call. If you think the previous info was on target, use the info provided to find out the appropriate percentage relation between ball diameter, pad diameter, and aperture size. If you already run BGA,

That pad had a 16 mil dia, so I arrived at 20 mil squares by adding 2 mils to each side of the pad. Following that logic, a 12 mil pad would use a 16 mil square. But a 12 mil pad is on a finer pitch that isn't mentioned, so you should definitely
