Notes:

1.Primary datum -C- and seating plan are defined by the spherical crowns of the solder balls (shown before motherboard attach). 2.All dimensions and tolerances conform to ANSI Y14.5M-1994.

3.BGA has a pre-SMT height of 0.5 mm and post-SMT height of 0.41-0.46 mm.

4.Shown before motherboard attach; FCBGA has a convex (dome shaped) orientation before reflow and is expected to have a slightly concave (bowl shaped) orientation after reflow.
