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.

Last week we visited a PCBA factory. We were looking at reflow ovens. A lot of them have a metal conveyor belt the boards sit on. On a double sided board, when you put the board on the metal belt, won’t the metal belt knock components off as they are only held on by paste?
We got a quotation sheet of four layers board but it greatly exceed our budget. So now we are thinking about reduce layers to save cost. Does this solution work?
Wat zou voor een ervaren persoon de gemiddelde snelheid zijn van het assembleren van componenten voor opbouwmontage op een PCB?? Ervan uitgaande dat ze een bureau hebben dat correct is ingesteld (pick and place station) and the PCB has solder paste already applied.
