We use an adhesive backed silicone sheet (McMaster P/N: 8622K41). We cut the sheet to the size of the cRIO and stick it on. You can do this to several cRIOs with one $38 sheet.

Another thing we do is use nylon fasteners. We do this for a few reasons:

1. Using plastic fasteners on the cRIO helps further isolate it from the baseplate.
2. You can trim all the fasteners to length (after they've been installed) with a pair of flush cutters.
3. We're tapping into 1/8" thick aluminum and the threads on the nylon screw will give before we can strip out the tapped hole in the baseplate.
4. They're light.
