How can the initial design of intelligent low-voltage monitoring units avoid the need for later rectification?

Early design is crucial to avoid later rectification; EMC design must be integrated into every stage.

Architecture stage: Plan shielding structure and grounding system.

Schematic stage: Select low-noise components and reserve filtering circuits.

PCB stage: Strictly partition layout, impedance control, and a complete ground plane.

Structural design: Consider gap shielding and cable entry treatment.

Design review: Conduct a dedicated EMC review.

Simulation verification: Use SI/PI tools for simulation.

Early design increases the probability of passing EMC tests on the first attempt, reducing later rectification costs and time.
