Better Angles. Better Flow. Better PCBs. Figure 1: Visual comparison of 90°, 45°, and Arc/Fillet trace routing on a PCB Introduction PCB trace routing is far more than connecting dots on a board. Every bend, corner, and curve in a copper trace directly affects signal integrity, manufacturing yield, and long-term reliability. Among the most misunderstood aspects of PCB layout is the treatment of trace angles — specifically, why the industry standard strongly discourages routi
