How to balance cost and effectiveness in EMC remediation of data center switches?

EMC remediation for data center switches should prioritize cost-effectiveness: First priority is PCB layout and routing optimization (zero cost), which can solve 30% of problems; second priority is adding ferrite beads, common-mode inductors, and Y capacitors (cost < 2 RMB/port), which can solve 50% of problems; third priority is adding shielding measures (cost 5-15 RMB), which can solve 15% of problems; fourth priority is replacing the main chip or modifying the schematic (cost > 50 RMB), used only in 5% of extreme cases. Yinte Electronics provides EMC pre-testing services and component samples to assist customers in completing remediation before PCB fabrication, reducing total costs by over 70%.
