Hi,
We are looking for suitable pcb material for pcie gen5(32GHz).
Our PCB is the NVIDIA CPU based custom board, According to the NVIDIA guide pcb stack-up document, the loss should be less than < 1.793dB/inch and the IT-170GRA2 material was used.
The Rogers is too higher spec than our requirement and expensive.
Instead of Rogers, Can you provide IT-170GRA2 or EM-890k materrial?
Our PCB is 8layer and the impedance lane is L1,L3,L6,L8.
Can you make IT-170GRA2 or EM-890k for the impedance lane?
For L2,L4,L5,L7 power and reference layer, high tg material (<170'C) can be used.
Can you mix the PCB material with the low loss and the high tg?
You can recommend the similar PCB material with IT-170GRA2 or EM-890k.
