Au contraire, mon ami. Although there is not "BGA" solderability test specified in J-STD-002A, the Test S can be used to assess solderability on BGA packages. [Joint Soldering Technology Committee ]

Chipmounter Placement Speed

I can only speak for the Fuji, but it is quite possible to get the maximum placement as long as you set the feeders and cut out some of the programming options that slow the machine. But then you may have a line-balancing issue, i know i did.
