How can the initial design of a power FTU avoid subsequent modifications?

FTU early-stage design avoids 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 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 to simulate signal integrity and power integrity.

Through early-stage design, the probability of passing EMC tests on the first attempt increases by more than 80%, significantly reducing later rectification costs and time.
