FreeLists / si-list / [SI-LIST] Re: Core thickness in between power planes!

[Tariq Abou-Jeyab <aboujeyab@xxxxxxxxx>]

Thanks for all who responded.
After looking back at the board, we figured
a way to flood the signal layers with power, to be
able to have a ground plane in the middle. So, the
core thickness is not an issue now. The closer the
more plane capacitance you get, the better.
Issue solved!

Thanks,
Tariq
