Hi All,
I'm working on a backplane design and come up with the following 7-layer PCB
stackup:
1) Signal (Single Ended Signals)
2) +5V
3) GND
4) Signal (Diffential Signals, high speed)
5) GND
6) +12V
7) Signal (Single Ended Signals and +3.3V trace)
I don't really need two GND planes, but the reason I added the second GND
plane (layer 5) was because of symmetry and balancing PCB stackup. How does
this stackup compare to the 6-layer stackup (without the second GND layer on
layer 5)?
Your comments/ideas would be greatly appreciated.
Thanks,
Kevin
