PCB vs Flyover Cables - Line hint:

Context Before
The alternative solution would be upgrading PCB materials, however, fly over cables are more cost effective and
Evidence
remain feasible for traditional server applications.
Context After
For VR NVL72, the design has turned toward cableless given the higher density and manufacturing complexity of AI server. The cost saved on improving higher manufacturing yields and assembly time reduction more than offsets the higher cost of the upgraded PCB materials. It is critical that all the factors that contribute towards insertion loss in the PCB are mitigated, hence PCB material upgrades are necessary for VR NVL72.
