If your circuit boards operate at 1 Gbps or above, just meeting a differential impedance spec for circuit boards is not enough. In current and next-generation boards, it is critical to also meet a loss spec. In this series of lectures, we show practical solutions to characterize, control and improve the loss in circuit board transmission lines by design and fabrication. We eliminate the confusion over topics such as attenuation, insertion loss, skin depth, copper roughness and surface treatment, optimum coupling for lowest loss, role of dielectric materials, which S-parameter has the most information, stack-up design for lowest loss, the role of vias in affecting insertion loss, which is better time or frequency domain measurements, and many more topics. Included with the video lectures are color PDF copies of the slides.
