Hi everyone !
The purpose is a 4 layers PCB.
My PCB manufacturer suggests different buildups for the same thickness of PCB.
What are the options to select one among the other ones ?
The other question is: when I select one buildup, am I going to be able to ask for the same buildup with another manufacturer ?
As far I understand impedances depend on layers' thickness …
So ...
Thank.
