Hi All

I am designing a USB type C 90R impedance controlled tracks. This is the first time I am doing high-speed tracks. I have some doubts regarding the impedance calculations. I will provide all the information as much as I know to succeed.

Below is the 4 layer PCB thickness

This is the calculator I have used from EEWeb to match the 90R impedance

The board stack up I would like to use is

Could anyone help me with the calculations I have created for 90R impedance is correct? Thanks
