Package_BGA:TFBGA-361_13x13mm_Layout19x19_P0.65mm - 3D model: TFBGA-361(12x12), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal BGA height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
