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

This might be totally wrong but if your using a 16 pitch reel in a 8 pitch feeder you are going to have to feed the feeder twice before it will be advanced far enough. This should be in your F4G or MCS30.

Depends what is adjacent to the step. 1206 chips could reside closer than say a 16 mil fine pitch. Larger apertures are more forgiving to height variations than small apertures.
