That's why they also glued them in epoxy. If you don't want you electronics to move (and thus break connections), put them tight in epoxy. And I mean completely glued in. No air left. This is as valid for modern solder joints as well as welded.

The AGC we restored was used for ground testing, so most of the modules weren't encased in epoxy. This made things much more convenient for us. We did have to dig through encapsulation to fix one module, though.

Modern electric guitar pickups are epoxied in place precisely to prevent unwanted vibration and thus the additional noise.
