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.

Depending on board size and layout, you could mount it with 1 or 2 screws in the middle portion of the board rather than 4 screws at the corners. I've seen several devices that either aren't bothered by a small misalignment, or that use 1-2 screws plus pegs to achieve tight alignment without adding much to the footprint.

  • \$\begingroup\$ I think this approach will work the best. I've experimented with some layout options, and there may be room near the middle for screw holes. Thanks! \$\endgroup\$ May 2 '14 at 16:54
