        Place a pad in the center prior to BGA placement, then CC with
silicon using squirt mode on you coater from all four sides. Design a
filling hole on back side and pump filler, after BGA assembly, till it
comes out from all four sides. Dam around BGA and squirt Si coating. It
is similar to submerging. Submerge the whole board in silicone...Leaving
pockets of air will pop corn at high altitudes.
