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: http://img94.imageshack.us/img94/7586/dsc9131.th.jpg [Broken] Do you know something more about that type of mounting? Where can I get these parts, which hold PCBs?
