Is there a quick solution to mounting pc board inside a plastic enclosure, where heavy vibrations might be a problem? Are there pcb mounts made of rubber or with a small spring to absorb the shocks? thanks.
I'm not sure about that, there probably is a way to do it. Possibly using computer silent fan mounts, though a bit pricey - http://www.acoustiproducts.com/en/ultra_soft_fan_mounts.asp suitable for higher frequency vibration rather than being dropped, shaked etc. Is it possible to pot the circuit with potting compound? This makes it very durable and weatherproof.
