Peter, I scanned the msgs quickly and didn't see a reply if there was one.
IPC-6012 Qualification and Performance Specification for Rigid Printed Boards clause
3.4.4 "The printed board shall have a maximum bow and twist of 0.75% for boards that
use surface mount components and 1.5% for all other boards."

Age old question with new requirements-
Where can I find the recommended accept/reject warp and twist criteria for
PCBs used for BGAs?
