Under BGA Rules!

[JohnsonMiller]

Hi Guys,

In some case we need to specify different rules/value for under the BGA area, I was wondering how we can specify BGA devices in design rules?

For such occasions I would create a Room that covers the BGA and use a custom query WithinRoom('RoomName').

As mairomaster suggested, you can also use rooms.
