How should a pneumatic shield box handle feed-throughs, filtering, and grounding?
Configure feed-throughs separately for RF, power, and data, then verify shielding, transmission, and grounding for each. One filtering approach cannot serve every port: an SMA pass-through, a USB 3.2 line at 20 Gbps, and a DC power feed have completely different requirements. Filtering has to match the signal band, protocol bandwidth, voltage and current, and the delivered mechanical structure. A photograph of a cable route is not evidence that the interface meets a shielding figure.
Key points
- Separate feed-through design for RF, power, and data paths
- Filter selection driven by band, protocol bandwidth, voltage, and current
- High-speed data needs a dedicated filter panel, not a generic feed-through
- Grounding continuity verified on the assembled unit
- Interface capability confirmed by test, never inferred from a photograph
