how to fix large film caps on the board Vibration

[Stefanoo]

Hi everybody,

I am wondering if anybody have experimented a functional way to fix large, rounded caps on the board to prevent parassitic vibrations.
Maybe glue them? If so, what would the solution to use?

Many thanks

Hot melt glue is commonly used.

If you look inside most all RF circuit boards you will see Hot glue beads everywhere...The most common way of damping vibrations on a cap in a board. Note that ANY variation (microphonics) of a capacitor will foul up RF tuning, hence the glue.
Of course hot glue will make for component removal very difficult....myself I would opt for Silicone,,,I would think the vibration absorption properties would be superior. M2C

What's wrong with a nylon capacitor mounting clamp or a couple of holes and a tie wrap?

That explains the gunk which when I was more innocent thought the capcitors had exploded. Nice info.

Silicon is often used, and tie wraps, we do MIL std and only use tie wraps.
