High Thermal Reliability HDI PCB Board HDI Design Denser Circuitry Lead-Free High Tg
To increase routing density, designers increase the number of layers, producing a complex stack-up. Manufacturers use sequential lamination processes to fabricate such complex designs.
Some of the common types of stack-ups are mentioned below:
1+N+1 – PCBs contain 1 build-up of high-density interconnection layers
i+N+i (i≥2) – PCBs contain 2 or more build-up of high-density interconnection layers. Microvias on different layers can be staggered or stacked
i+bN+i (i≥2) – Includes buried vias
Any layer HDI – All the layers of a PCB are high-density interconnection layers. This allows the conductors on any layer of the PCB to be interconnected freely with copper filled stacked microvia structures

What are the advantages of HDI PCBs?
1. Phenomenal versatility: HDI boards are ideal where weight, space, reliability, and performance are primary concerns.
2. Compact design: The combination of blind vias, buried vias, and microvias brings down the board space requirement.
3. 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.
4. High reliability: The implementation of stacked vias make these boards a super shield against extreme environmental conditions.
5. 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.
