That you have one BGA of 30 BGA that has voids, makes us wonder what's the deal with that one BGA. Especially given that this is the initial run of a product with BGA at your plant, it really makes us want to understand just what is driving the voidi

Sn62 eliminates voids on BGA ?

I'm curious why your customer is concerned with BGA voiding. Normal process voids, even well in excess of IPC "limits", don't effect reliability so why monkey with the process to get rid of a non-issue?
