Standard Stackup + Controlled Impedance Deep Dive

Multidisciplinary product creation powered by your unconstrained network. Work concurrently across design, sourcing, and manufacturing with real-time insight. 35+ Years of Excellence: https://www.altium.com/develop?utm_source=youtube&utm_medium=video&utm_campaign=prior-2026-releases In this video, Tech Consultant Zach Peterson explores the concepts of controlled impedance and controlled stackup design in PCB manufacturing. He discusses the advantages and disadvantages of each approach, and we shows you how to specify impedance in Altium Designer. Zach also answers a viewer question about the use of controlled impedance when using a standard stackup. Finally, he compares the results of impedance calculations in Altium Designer with those from JLCPCB's impedance calculator. 👉 Resources from this Episode: - Impedance Control: How to Specify Your Requirements for PCB Manufacturers: https://resources.altium.com/p/pcb-manufacturing-and-impedance-control-how-specify-your-requirements - Your Quick Guide to Understanding PCB Impedance Tables: https://youtu.be/TxJmlrcRnfw?si=_wPCskjthTAgwvvM 👉 Exclusive Note: Altium is transforming the electronics industry so thoroughly that some of our content needs a moment to catch up.
