The template tells you what a good stackup looks like. The Stackup Design Series tells you why it is structured that way, how to adapt it when your project has different requirements, and what to do when the template does not fit. Same four-tool format — explainer, mini-course, cheat sheet, and design wizard — for stackup design.
The physics behind layer ordering, reference plane placement, and return path continuity. Four tools that take you from copying a stackup to understanding one — so every decision you make is based on electromagnetics, not convention.
