How to Secure PCBs in a Stratospheric Balloon's Electronics Box?

[kmail]

Hello

I'm designing a box for 6 PCBs. It will fly on stratospheric balloon. Do you know a solution of mounting PCBs to box walls, which will provide strong and stable connection? I was thinking about slots in internal walls, but that can be not enough.

I found interesting solution:

Do you know something more about that type of mounting? Where can I get these parts, which hold PCBs?

That looks like it was custom machined.
You can get regular diecast boxes with pcb guides from the normal electroncs supplies.

But - if you are concerned about weight and ruggedness more than easy servicing I would probably connect all the boards together in a stack with screw standoffs between them and then put them in a box on some sort of foam/rubber/shock-absorbing mount
