50-Ohm Impedance Calculation for PCB Traces
30
May

50-ohm impedance is not a magic trace width; it is a result of copper width, dielectric height, Dk, copper thickness, solder mask, and reference planes. This guide explains how PCB trace impedance calculation works before your RF or high-speed design reaches fabrication.

May

Aluminum PCBs do not fail wetting because “aluminum is difficult”; they fail because process windows are copied from FR-4 and then blamed on the board. This guide breaks down the real fixes: surface finish control, flux activity, thermal profiling, paste storage, stencil design, and inspection feedback loops.
