High-Speed PCB Stackup Design Guide: From 4-Layer to 20+ Layers
A well-designed PCB stackup is the foundation of signal integrity, power integrity, and EMC performance. This guide covers high speed pcb stackup design principles for 4-layer through 20+ layer boards, including symmetry rules, signal-ground coupling, HDI structures, impedance control, and a manufacturer-ready checklist. Mastering high speed pcb stackup design is the first and most critical…
