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

AI Thread Summary
For securing PCBs in a stratospheric balloon's electronics box, a strong and stable mounting solution is essential. Suggestions include using slots in the internal walls, though this may not provide sufficient stability. An alternative method involves stacking the PCBs with screw standoffs and placing them in a shock-absorbing mount, prioritizing weight and ruggedness. Regular diecast boxes with PCB guides are available from electronics suppliers for easier access. Custom machined parts may also be an option for specialized mounting needs.

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

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
