> If you're shielding against EM weapons, the weight will quickly stack up more than just the signal wire. Agreed. The signal wire while being large antenna for EMI isn’t a problem at all. Filters, rugged transceivers, chokes and your problem is solved there. EMP is a threat where you are able to load all traces on the PCB and in the chips themselves with varying potentials instantly. We’re used to securing transients on the signal lines. Not on the 10mm trace from chipA to chipB.
