Kevin,
Discuss it with your vendor. You have to just define the board thickness =
& matched impedance.
Vendors can then give you the options depending on the best stack, core =
thickness & dielectric constant of prepeg.
Hope it helps.
Thanks

Subject: [SI-LIST] PCB Stackup - 4 vs 6 layers
Given both PCBs have the same dimensions (Width and length) and =
thickness,=20
which stackup is cheaper to build?
4-layer PCB with a big core
Sig
GND
Big Core
PWR
Sig
or 6-layer PCB with a smaller core
Sig
GND
Sig
Smaller Core
Sig
PWR
Sig
Thanks,
Kevin
