Pourquoi le régulateur s'est cassé sur le PCB lorsqu'il a subi un test de vibration?

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.
