I was searching for low loss high speed PCB material and found the datasheet of the following materials.
The above dielectric constant values Dk representing the Core material. What are the dielectric constants Dk for Prepregs R-5670(K)/ R-5670(N)/ R-5670(G) ?
In which thickness (glass cloth style) these Core and Prepreg are available ? Are they available in 106, 1080, 2116 and 7628 ? The reason of asking this question is, we need to specify the thickness of Core and Dielectric in the Stackup Editor of the PCB Design Tool along with the dielectric constant value Dk.
- MEGTRON6 Normal glass cloth: R-5775(K)/R-5775(G): Dk = 3.62 @ 13GHz
- MEGTRON6 Low Dk glass cloth: R-5775(N): Dk = 3.34 @ 13GHz
