Up to which altitude does the STM32 work properly?

I want to shoot it in about 20km altitude, but I have doubts about if the microcontroller still works under that low pressure. Does also anyone know the distance of the conducting paths?

to avoid issues with radiation, short tracks on the pcb, ...

Radiation is mostly about internal MCU / semiconductor problems.

With small enough structural sizes, each alpha particle hit will distort internal states, i.e. flip RAM cell contents.

That means, albeit not physically damaged, it will do weird things up there.
