I have a question regarding dielectric constant of FR4. How does Dk change
in case you increase the temperature from room temperature to maybe 150
degree C.
I remember I have seen once a curve somewhere, which showed  Dk increasing
drastically when the temperature went up.
Is this correct and what would be the explanation behind. 

Walther
