Designer/Fab expert,
How the industry is doing as far as SOLDER MASK clearance is concerned?
Are designer prefer to put right clearance so that the fab house does
not have to modify it? And if the designer is creating the solder mask
layer by keeping correct solder mask clearance,, does a note from that
point of view is required on fab drawing?

This question is bec' of solder mask clearance requirement is varying
from pads of different components to different like BGA, Via in pad,
etc.
