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.
Welcome to element14.
What is the application?
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.
