When you google for the specific materials in the "Description" column, you can find their specific characteristics e.g. http://www.ventec-group.com/products...-47/datasheet/

Hello,

I am talking about the following stackup:

https://www.imx6rex.com/download/design-files/imx6-rex-module/v1i1/docs/iMX6%20Rex%20Module%20V1I1%20PCB%20STACKUP.pdf

Here different dielectrics contant values i.e. 4.6 and 4.12. I wonder if all the dielectrics are Fr4 or you used other than Fr4 i.e. Rogers etc. Please let me know that. I will really greatful to you.

I am not sure which board you mean, but the iMX6Rex module stackup can be found on the main page, here: https://www.imx6rex.com/download/des...%20STACKUP.pdf

I am curious if you people used fr4 dielectric or hybrid dielectric in Imx6 rex? If hybrid then can you please mention the substrate of each layer? Thanks in advance.
