Well, the electrical components do have clearance holes for the hardware we're using...

It allows us to align all of our hardware in CAD and ensure that the electronics are robustly fastened to the baseplate. We typically use 1/4-28 on 1/8" plate. For the Talons, we use #10-32. For the Digital Sidecar and Spike Relays, we use #6-32.

All of our fasteners holding down electronics are Nylon screws to ensure that there is proper frame isolation. Teams have had issues using shielded DB-37 cables and DB-25 cables and didn't realize that the shield was touching metal fasteners, creating a short between chassis and potentially ground/power.

Not to mention, using Nylon screws is significantly lighter than using your typical metal fastener in this application.
