It can surely be a reason for a vibration failure if the module isn’t mounted flush with the board and can actually moved by hand. Copper is horrible when repeatedly flexed.
I’d suggest strain relief of the assembly with some elastic compound to the board, if possible. It’s also important to evaluate if the module is ‘top heavy’, since the regulator body will leverage to the board.

The assembly note states: Bake bare PCBs in a clean and well ventilated oven prior to assembly at 125*C for 24 hours. Why is this necessary?
We plan to visit factory next week. Could we know more about how many basic PCB testings in EMS field?
After We have assembled the Virtex-4 FPGA BGA package on our custom design PCB, we check for short circuits between all power grounding and they shows short cut between each other. Please tell us about any process for debugging this issue.
