We have never studied this, but here's what we'd guess. If there are void in BGA solder balls at inbound: * A proper reflow recipe will eliminate the void. * A poor recipe will allow the void to remain and possibly generate additional void.

yes they can, we have re-reflowed BGAs for voids and have noticed that they are still there.
