Can there be a problem to run an electronic board in an atmospheric pressure of 10 bars? I think of the chemical capacitors, is there a risk that the housing collapsed?
I would suggest that you're best asking the component supplier(s) for their recommendations. As far as I know it's not normally mentioned in datasheets for commercial components.
I agree with Andy, you should read the datasheets for each component on the board. For the most part, all components will be able to handle those pressures.
Alternatively, by encasing the circuit in an epoxy, you can raise the resistance to atmospheric pressures.
