SMD BGA Pads

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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?

Br.

	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.
