Roughness of Copper and its Effect on Signal Integrity

Bert Simonovich, a very well-known expert in the signal integrity community, is our guest in today’s podcast episode. He developed the "Cannonball-Huray" model a transmission line loss modeling, which has been adopted in several popular EDA tools.

We will be discussing several topics relating to copper roughness, including different approaches to ensure signal integrity in your PCB design.

1:49 Bert's background
3:43 Bert retrospects using photo tools which is now the photo plotting with Gerbers. His experience helped him understand the mechanics of PCB construction
7:58 A client’s demand led to extensive research involving dielectric material comparisons and foil roughness
11:44 With various PCB surface roughness models, how to determine which process to move forward with?
20:26 Bert gives a detailed explanation of how copper is being used in PCBs
23:08 HDP user group international published a research paper Smooth Copper Signal Integrity in 2016
31:31 Bert and Zach agree that PCB construction is complicated and it is highly recommended for PCB designers and SI engineers to learn more about the fabrication process
39:09 What does reverse-treated foil means, and how does it relate to the power layer?
49:33 Read Bert’s DesignCon Paper: A Practical Method to Model Effective Permittivity and Phase Delay Due to Conductor Surface Roughness
