There is a heat conductive rubber gasket material for automotive use...It's
the higher frequency mechanical thumps you need to get rid of.

Hello Raj,
I integrated a Symmetricom model X72 Rb into a Down East Microwave (DEMI)
chassis
and it does experience microphonics. This was for a friends 10 GHz
transceiver used for portable work.
So getting rid of the microphonics is important.
Somehow I need to mechanically isolate the Rb from the chassis and still
have a heat sink.

While comparing a Rb FE5680 frequency reference with another RB or GPSDO
I find that tapping a Rb unit causes a sudden shift in the scope display
meaning the frequency has slightly shifted momentarily and locks back
steadily with a phase shift. This does not happen in another Rb FE5680.
Would something be loose I wonder ? Any experiences?
Cheers
