Design-stage support for PCB, filtering and switching-noise decisions before compliance testing becomes a late-stage problem.
EMC performance is strongly affected by switching-node geometry, return-current paths, grounding, filtering and component selection. Addressing these issues during design can reduce late redesign risk.
Review switching nodes, grounding relationships, power/signal interfaces and filter architecture.
Examine trace routing, return loops, ground planes, high-di/dt loops and switching-node geometry.
Evaluate common-mode chokes, differential-mode chokes and X/Y capacitor networks according to the noise mechanism and current path.
Support investigation of EMI issues using design measures such as snubbers, shielding, layout modifications and filter changes.
