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

.5mm pitch should use SMD pads and follow pad size calculation for Non-Collapsing ball. And another question I have is if a pad uses 0 soldermask expansion would it still be classified as soldermask defined

. Non-collapsing BGA's have larger pads to accommodate via-in-pad and establish an adequate annular ring. The BGA ball does not collapse around the edge of the pad like a collapsing ball does
