LFBGA448 package information

This LFBGA is a 448 balls, 18x18 mm, 0.8 mm pitch, low profile fine pitch ball grid array

package.

Figure 73. LFBGA - 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.
