impedance control with different prepreg styles in a dielectric
Hello guys.
My layer stackup looks like the picture
Lets say that:
- Dk for 2116 is 3.4
- Dk for 7628 is 3.7
I need a 50 ohm impedance in layer 1 (layer 2 is ground).
For impedance calculations, how do I manage two different values for Dk?
I had a look at the document below but it doesn't help too much
**broken link removed**
Thanks!!
