Hi Experts,
From my understanding, HDI build-up layers require thin prepreg layers,
leading to very thin trace widths for 100ohm differential impedance control
- and your high speed serial links would suffer great conductor loss.

How do you mitigate against this?

If your design has many build-up layers with thin build-up layers on either
side of your stripline, then it is impossible to even get something like
100um (4mil) trace widths for your 100 ohm differential pairs!!

Regards,
Carson
