I it difficult but doable. It would be interesting to see how the customer
measures the impedance as well?

This depends on the materials, dielectric and line dimensions which
contribute the standard deviation. Generally +/-5% is difficult to achieve,
although we have a few designs that are capable @ a 5% tolerance.

Subject: [TN] Impedance Spec +/-5% and Cpk of 1.33
Hi folks,
Is the industry capable of this requirement?
Impedance +/-5% with a demonstrated Cpk of 1.33.
This could apply to Single Ended 50 ohms or 100 ohms Differential.
Also, this is on a Flex Circuit.
Thanks,
Glenn
