Standard Stackup + Controlled Impedance Deep Dive

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.
