Just throwing this one out there for opinions. I've got a project that's going to consist of a 12"x9.6" board, basically a 2-layer backplane, which is eventually going to have about a dozen smaller 4x3" daughterboards mounted at a right angle to it on a bus. Reason for the size is that I can just toss it in a standard ATX PC case and boom, enclosure with power and USB ports.
The question is, does anyone around here have any off-the-shelf connectors or hardware (Digikey/Mouser/LCSC) they like to retain a board and keep it from flopping around?
I only have about 40 signals that need broken out, plus power. Bitrates are only around 10-20MHz so pretty much anything that makes contact is fine. I've considered:
- Using DDR4 DIMM sockets, but 288 pins is a little overkill considering I have to assemble this thing.
- Using two of these on the backplane and two right angle mates with jackscrews, currently what I think is the best option.
- These seem nice but I'm not sure how secure I trust a snap-in card guide to be.
- These are awesome and we use them in test equipment at work but they're way too expensive for one connector.
I'm not going to throw this thing down a flight of stairs, but I'd like to be able to move it around without having everything fall out the side every time. I'm sure someone around here has had to rigidly mount a free-standing right angle board to another PCB at some point, what'd you use?
Pretty easy problem to solve but I'm not making custom metalwork/hardware just for a personal project and finding board mounting hardware with the Digikey/Mouser parametric search has been a crapshoot because it's just scattered everywhere.
