widths below 50\u03bcm. The problem with subtractive etching is the &#8220;undercut.&#8221; Because the etchant attacks the copper both vertically and horizontally, you end up with a trapezoidal trace cross-section. At 25\u03bcm, that undercut isn&#8217;t just a rounding error; it\u2019s a structural failure. It creates unpredictable impedance, massive signal reflections, and makes it impossible to maintain the tight tolerances required for 112 GHz
