I'm designing a small board, with these quick disconnect tabs along the edges. The board will be mounted to a non-conductive surface. I had initially planned to use screws at the corners, but the shape of the components means this results in a significant increase of footprint, and I'd like to keep costs down. My hope is to avoid margins, such as those in this (trivial) example.
Is there a more efficient way to mount this board, in terms of board area? I've considered soldering on ring connectors that will stick out the corners, and putting screws through the rings. That seems weak and unprofessional, though. Slot mounting is unfavorable, since the board will be mounted on a flat surface with space around it.
