Perforated panel electrical box effect
Perforated metal allows air flow through so the electronic equipment won't overheat. Honeycomb has the added advantage of high open area for cooling -- low loss coefficient through the vent, which at the fan is important (that's where the highest speeds are). There's probably no pat answer to your question without an EMI specialist knowing the frequencies you're trying to keep from. CSPP panels mount inside contractor pull boxes (CS/CSKO. CHKO) to provide a panel mounting surface. Panels are mild steel finished in ANSI 61 gray. Literature [6, 7] The shielding efficiency of double-layer open-hole boxes was studied, the results show that there is a resonance problem in the double-layer shielding cabinet, and the arrangement of the holes has a greater impact on the shielding efficiency of the double-layer shielding cabinet. Unlike solid panels, these panels have a grid of holes sized to fit self-tapping screws, so there's nothing to measure, mark, or cut.
