When handling BGA components with hundreds of pins and sub-0.5mm pitches, traditional through-hole vias become a physical impossibility. High-Density Interconnect (HDI) structures solve this space crisis.
Standard PCB design courses teach you how to make a board function . An advanced masterclass teaches you how to make a board survive . The Masterclass 2025 focuses on three pillars:
The masterclass teaches how to use a VNA (Vector Network Analyzer) or simulation tools to plot PDN impedance. The goal is to keep impedance below the target impedance (e.g., 1mOhm for a 1.8V core rail drawing 10A). Students learn why simply placing 10 capacitors of 0.1uF leads to parallel anti-resonance —a dangerous peak that can cause clock jitter.

/ Loss Tangent): This dictates how much signal energy is absorbed by the dielectric material as heat. Ultra-low-loss materials (like Rogers 4000 series, Panasonic Megtron 6/7, or Isola Tachyon 100G) feature a Dfcap D sub f below 0.002.
AC coupling capacitor placement layout optimization. Total avoidance of stubs, layer transitions, and tight 90-degree trace bends.
This module covers the "art of black magic" demystified:
Understanding the physics of transmission lines is critical. Modern designers must account for skin effect and dielectric loss at frequencies exceeding 30 GHz.
The course’s depth is best understood through its detailed breakdown. Here is the real-world curriculum as outlined in the course, divided into its core modules:
Students must produce:
Symmetrical differential pairs with less than 0.5mm length mismatch. Ground plane references must remain completely unbroken beneath traces. Conclusion
