LFBGA448 package information
Figure 73. LFBGA - 448 balls, 18x18 mm, 0.8 mm pitch, low profile fine pitch ball
grid array package outline
1. Drawing is not to scale.
2. The tolerance of position that controls the location of the balls within the matrix with respect to each other.
For each ball there is a cylindrical tolerance zone fff perpendicular to datum C and located on true position
as defined by e. The axis perpendicular to datum C of each ball must lie within this tolerance zone.
Each tolerance zone fff in the array is contained entirely in the respective zone eee above. The axis of each
ball must lie simultaneously in both tolerance zones.
