A Deep Dive into the Skin Effect in PCB Traces
Introduction: The Hidden Challenge in High-Frequency Circuit Design In the world of electronics, once a signal’s frequency crosses a certain threshold, physical phenomena that are virtually invisible at DC or low frequencies begin to surface — profoundly influencing circuit performance and reliability. Skin effect is one of the most critical among them. Read more
