        What a PCB is made of (build-up), determining a suitable build-up, and manufacturer/manufacturing considerations. Second part of video discusses how to choose a suitable stack-up for your PCB design (i.e. what sequence of layers you should assign (GND/PWR/SIG)) for signal integrity, EMI, etc.
