Every body
I get a problem for PCB stackup, and I can't make the successful stackup.
Attached file is the original stackup data for reference.
<<Stackup.xls>>
Now I want to change the stackup to follow the conditions as below:
a) Layer 3 and Layer 8 don't change, because RAMBUS signals in those
layers.
b) The PCB's thickness doesn't modify. The total thickness is 1.6mm ¡Ó10%
(62.4mil ¡Ó10%).
c) I have to rout traces impedance for 75 ohm in any layer except layer 3
and layer 8.
Does any one know the solution?
Best regards
