Share your PCB stackups

Hi!
For 4L- board I used PWR/SIG at L1 and L4, with L2 and L3 as GNDs (one GND polygone or more, depending on number of GNDs). Guy from previous company suggested this stackup. Ric Hartley also mention it in https://www.youtube.com/watch?v=52fxuRGifLU with Robert. He mentioned that this stackup is good for digital boards, if I remember correctly. If there are sensitive tracks, they should be hidden inside the board, and with this stackup that is not possible.



Regards,
Miloš

Hi dear Robert. I designed a 16 layer PCB. KU060 Xilinx FPGA with DDR4. I had 3G SDI with 75Ohm Impedance. I hope someday anyone can use.

Thank you very much giannisasp

Hi Robert,
Here is a small contribution from me as well.
Its a custom 6L stackup from an FPGA board with DDR2 that I designed some time ago. I have reused that stackup elsewhere as well.
I hope someone finds it usefull.
Giannis.

And here is my contribution. All the stackups are based on my article here:
