I'm basing a design on the MCIMX6ULL_CM EVK and have a query about the board stack-up. The copper thickness, number of layers and overall stackup height are shown on the gerbers, but not the individual prepreg layer thicknesses.
I can infer the prepreg thicknesses from the controlled impedance table (based on a calculation using the impedance and track width), but I would like this to be confirmed, if possible.
I notice my question has been 'Branched to a new discussion'. However, when I click on the 'discussion' link, it takes me to a page that says:
This place or content does not exist or access to it is restricted. If you think this is a mistake, please contact your administrator or the person who directed you here"
Any info on this?
My apologies. You can get individual prepreg layer thicknesses for the MCIMX6ULL_CM board by accessing cross-section of board file.
I hope this helps!
