A try was done to install insulating foam inside the EM shield boxes. Armaflex foam was provided by MPE in several adhesive sheets. After trying to cut it to setup the light holes we realized that the foam along the cuts was very dusty and we decided to not install it...
Just a 5mm PVC foam sheet was added between the PC and the PC flange support, inside the box.
JZ provided new cables for the PC: they can be plugged directly into the white panel connector from inside the EM box. These new cables have been additionally insulated using spiral binding cables.
