PCBs are the heart of almost all electronic products, carrying the components and copper wires that enable their functions. Electroplating is often included in the manufacturing process, and electroplating varies from design to design. This forces simulation and optimization engineers to constantly create new models. What if most of this work could be handed over…

1.Key points of EMC circuit filter design: L1 is a common-mode inductor, which can attenuate common-mode interference, suppress interference inside the board and external interference, improve the product’s anti-interference ability, and reduce external radiation through the 429 signal line. The common-mode inductor impedance selection range is 120Ω/100MHz ~2200Ω/100MHz, and the typical value is 1000Ω/100MHz; C1…
