I have an issue with an assembled board that occasionally experiences flex
in routine use, and I need to determine whether it is a reliability concern.
Prior to engaging in a full-blown reliability study, I would like to know
whether there are any industry specifications (IPC or otherwise) that relate
to finished assembly flex (bow/twist).

The closest thing I have found is IPC-A-610C, page 10-16, regarding bow and
twist after soldering.

Are there published reliability studies (solder joint, trace, other
features) related to bow/twist/flex of assembled boards?

Please advise.
