Default How Do I Make a PCB Shock Resistant?

Good morning, all. I'm brand new to hands-on electronic repair so please pardon any silly questions.

I recently acquired a Geiger counter manufactured in 1962 and I am rebuilding it. The PCB is 4" x 4" and 0.062" thick. The part of the chassis to which it mounts has four steel legs that protrude 1.45" perpendicular to the plane of the chassis. The four corners of the PCB screw onto these steel legs..

I would like to know some options for making the PCB more shock resistant should the unit ever get dropped. Is there any such thing as, say, shock-resistant washers that could go over the four screws and sit between the PCB and the steel legs to which it's mounted? Or is there a better way?

Any suggestions geared towards a newbie would be greatly appreciated. Thanks, all!

Kindly,

Matthew Connor


You can always encapsulate it in two part epoxy. MG Chemicals (and
others) sell these kits.

Mind you you won't be able to easily remove the encapsulation later
unless you soak the blob in acetone for a day or two to soften the epoxy...
