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.

estoy diseñando un 2 capa de PCB con componentes en ambos lados. Los componentes SMT son un lado de la PCB, pero TH (a través del orificio) Los componentes están en ambos lados.. Necesito entender algo mencionado por el proveedor llamado lados primario y secundario..
Envío mi diseño de PCB al fabricante para su prototipo., pero devuelven muestras de PCB desviadas con zig-zag adicional. ¿Por qué tiene líneas en zigzag?? Reducir la interferencia?
estoy haciendo un 4 Prototipo de PCB de capa que utiliza un mcu bluetooth conectado a una antena de chip de 2,4 GHz. Estoy pensando en qué hacer con la línea de alimentación., si se debe enterrar en una de las capas intermedias, o a la izquierda en la capa superior. Conseguir un 50 línea de ohmios, ¿Debo elegir una capa superior con un ancho de 13 mil o una microstrip enterrada con un ancho suave de 7??
