Why 50 Ohm Impedance Is Common in PCB Design Impedance in PCB work usually means the characteristic impedance of a transmission line. It describes how a signal travels along a copper trace. Trace geometry, dielectric material, copper thickness and the reference plane all set that value. For high-speed digital and…

PCB Trace Routing: Three Reasons to Avoid 90-Degree Corners A right-angle corner is not an automatic defect, and many working boards carry them without trouble. The rule matters because a corner changes the geometry of a conductor, and geometry drives electrical behavior. Whether that change matters depends on signal speed,…
