Field guide
SI Design Explainer

Eight sections covering the full signal integrity picture โ€” from why a trace stops being a wire to how you pick a stackup for high-speed interfaces. The foundation everything else builds on.

Mini-course
SI Mini-Course

Ten chapters, ten quizzes. Transmission lines, controlled impedance, return path, reflections, termination, crosstalk, differential pairs, eye diagrams, PDN interaction, and stackup design โ€” covered in sequence, with checkpoints after each.

Interactive tool
SI Design Wizard

Five questions about your signal โ€” rise time, topology, stackup, interface type, primary concern. The wizard gives you signal bandwidth, critical length, target impedance, and a specific termination recommendation. For your board, not a textbook example.

Cards
SI Flashcards โ€” Terms & Rules

The key SI terms and the eight design rules as flip cards. Track what you know and what needs review โ€” a fast refresher before a design review or a routing session.

What's next

SI is one part of the board.
Master all of it.

The PCB Design Mastery Course covers the full picture โ€” from schematic to production-ready layout across 24 modules. Signal integrity, EMI control, multilayer stackups, manufacturing handoff. Built for engineers who want to stop guessing and start designing with intent.

24 modules โ€” concept to manufacturing files, nothing skipped

Real project walkthrough โ€” follow a live design, not slides

EMI control included โ€” the topic most SI courses never touch

12 months access โ€” self-paced, revisit anytime, free updates

Checklists, templates & tools โ€” download and use in your own projects

Certificate of completion โ€” something concrete for your profile
