Learn essential PCB ground layout principles through practical experiments and real-world examples in this comprehensive video lecture presented by Hans Rosenberg. Explore fundamental concepts like current flow patterns under tracks, copper fill techniques, and the impact of different layer configurations. Master critical design rules to prevent ground-related issues, including proper ground plane implementation, VIA placement strategies, and handling gaps in ground planes. Examine specific case studies involving FPGA board redesign, star grounding methods, and the integration of digital and analog components on a single board. Gain hands-on insights through detailed experiments demonstrating the effects of track cutting, filtering, and various grounding techniques, all aimed at improving PCB design and performance.
