You need to call the specific manufacturer for each of these materials,
as they may vary.

>
> Thanks to everyone who tried to help with my original question about
> pre-preg material dielectrics.
>
> As it turns out I used the wrong term.  What I meant was, I would like
> to get the dielectric constants for the materials commonly used to
> make PCBs.  These include FR4, Tetrafunctional FR4, G10, GTEK,
> Polyimide, Cyanate Ester, Teflon and the new material from GORE, what
> ever it is called.  Would it be possible to get the ranges as well,
> since I know that the dielectrics are not necessarily constant.
>
> Assume that testing is out of the question.
>
> Since I am at it.  Have I missed any materials?  I know that there are
> some new ones that I may  not be aware of.
