Mechanical Engineer here, not an EE.
I have some environmental sensors that need to be a part of a flow path. It occurred to me that it might be possible to have a metal "can" that sealed to the board around the sensors by sodler, providing a gas-tight connection. The current solution uses a plastic part with an oring and through the board screws, and it doesn't work well, as a bonus.
How would I communicate this to the EE's doing the board layout?
Ideally, there would be a lid like rf shields that could be snapped on and off and be gas-tight when on.
