What are the advantages of HDI PCBs?
Phenomenal versatility: HDI boards are
ideal where weight, space, reliability, and performance are primary concerns.
Compact design: The combination of blind
vias, buried vias, and microvias brings down the board space requirement.
Better signal integrity: HDI incorporates
via-in-pad and blind via technology. This helps in placing the components
closer to each other which cuts down the signal path length. The HDI technology
removes via stubs and therefore reduces reflections of signal and thus
improving signal quality. It therefore
remarkably improves signal integrity due to shorter signal paths. Also read:

High reliability: The implementation of
stacked vias make these boards a super shield against extreme environmental
conditions.
Cost-effective: The functionality of a
standard 8-layer through-hole board (standard PCB) can be reduced to a 6-layer
HDI board without compromising the quality.
