PCB Layer Stackup Analysis - Routing Over Split Planes and Signal Integrity

Explore the critical effects of routing PCB tracks over split planes in this comprehensive 56-minute video tutorial. Examine various PCB layer stackup configurations through detailed simulations and practical examples, starting with symmetrical designs using solid ground planes on top and bottom layers, then progressing to more complex scenarios involving split planes. Analyze the impact of asymmetrical stackups, gaps with bridges, and partial cutouts on signal integrity. Investigate crosstalk phenomena when routing over gaps in both near and far planes, including differential pair routing considerations. Learn through hands-on demonstrations using professional signal simulation software, with insights into how AI is being integrated into modern PCB design tools. Gain practical knowledge for making informed decisions about PCB layer stackup design and understanding the trade-offs between different routing approaches over split power and ground planes.
