This article, through high-frequency board debugging cases, reveals common misconceptions about impedance matching \u2013 from the stability of material Dk values \u200b\u200bto the coupling effects of adjacent signal lines. You will find that what is truly critical is the stable performance across the entire operating frequency band, not perfect matching at a single frequency point. When choosing a manufacturer, engineering adaptability is more important than technical parameters. Let's rethink..."}
