Trace spacing depends on the applied voltage, and also how dirty/humid your environment is. If your PCB has soldermask, then usually a few mm is fine for line level voltages, but exposed pads require caution because current may conduct through dirt and moisture on the PCB surface. Splet05. apr. 2024 · One rule of thumb for defining spacing between each trace in a differential pair is the “5S” rule, sometimes called the “5W” rule in application notes and other PCB design guidelines. The 5S rule states that the spacing between two lines in a differential pair should be a factor 5 larger than the width of each trace in the pair. انتقال ارز با trc20
