How Solder Mask and Surface Finish Create Minor Reflections in Transmission Line
Understanding how solder mask and surface finish create minor reflections in transmission line is critical for high-speed PCB signal integrity. These subtle impedance discontinuities, often below -20 dB, accumulate in 10+ Gbps designs, degrading eye diagrams and increasing bit error rates. This guide consolidates expert engineering insights to help you mitigate these effects. The Physics…
