How to ensure continuity in the overlapping of power DTU enclosures?

Ensuring DTU housing overlap continuity requires guaranteeing contact surface conductivity and tightening pressure. Remove the insulating coating from the contact surfaces to expose the metal substrate, or apply conductive paint. Fill uneven areas with conductive pads (such as beryllium copper springs). Tighten screws with a spacing of less than 5 cm and a consistent torque (e.g., 0.5 Nm) to ensure uniform pressure. The overlap resistance should be less than 10 mΩ. For moving parts (such as doors), use hinges or braided straps for bridging. During testing, use a milliohm meter to measure the overlap resistance; it should meet requirements. Ensuring continuity reduces grounding impedance, improves shielding effectiveness, and enhances immunity.
