In today's technological environment, circuit board designs no longer just simply connect signal lines. We need to consider the issue of electromagnetic compatibility on PCB boards to prevent different types of signals from interfering with each other. This study is in accordance with the circuit provided by the 99 EMC design competition. With circuit analysis and the specification of each component device, the optional position of each component on the PCB board can be made. Moreover, with the EMC design guidelines for circuit layout and the EMIStream for system simulation, this design achieves the standards of general industry electronics for electronic products.
