Ask Me Anything about Controlled Impedance

Ever feel like controlled impedance is gaslighting you?

You followed the calculator, set the trace widths, matched your pairs… and the signals still reflect, skew, or degrade.

Ask us about:

  • Stack-up strategies
  • Line width tolerances and copper roughness effects
  • Materials that mess with your signals
  • Anything else making your CI a guessing game

Get clear, practical answers from engineers who’ve debugged these problems countless times.

Drop your questions in the comments.

Can you simulate and provide impedance coupons for validation during fab?

What is your maximum trace width and spacing variation tolerance during etching?

An impedance model is generated in the early planning stages of the job. Impedance test coupons are also added to the job during the CAM stage.
