I'm looking to connect 2 small PCBs. I have up to 10 signals that need to be passed from 1 PCB to the other. The 2 PCBs sit perpendicular to each other, and need to be detachable; 1 PCB is an 8 layer, while the other can be anything (doesn't exist yet). Consumer device, so the speed of the signal and all that can be neglected for now; as long as the 2 boards are electrically connected and can be disconnected, it is okay.
The easiest solution would be to use an edge card connector. However, I have less than 6.5mm in width, and need the height to be minimal. I was thinking some gimmicky way to use slots in order to connect the PCBs in a puzzle like fashion, but I feel the connectivity reliability would be questionable.
I'm open to any crazy ideas; or if anyone has found really small connectors, or done something similar, please feel free to share your experience.
