Yes, you would use a Non-Collapsing BGA Pad. 

IPC has no recommendations on Solder Mask defined BGA pads. 

This issue is between you and your assembly shop and quality control managers.

I want to create BGA 0.40 mm pitch footprint.

So if the pitch is 0.50 mm or less then we should create a SMD ( solder mask defined ) pads.

i entered 0.40 mm pitch and BGA Non-Collapsing Ball but the Library Expert is always creating NSMD pads?

Is it possible that the Library expert creates SMD pads for BGA per IPC standard?
