Multi-layer HDI Blind/Buried Via Circuit Board

HDI (High Density Interconnector) blind/buried via board is a type of printed circuit board (PCB) produced using a technology that employs micro blind/buried vias, resulting in a high circuit distribution density. HDI is a compact product designed for users with low-capacity needs.

Blind Vias: Blind vias are a type of via that connects inner layer traces to surface layer traces on a PCB without penetrating the entire board. (Typically used in 4-layer boards and above)

Buried Vias: Buried vias are a type of via that only connects traces between inner layers, and are not visible from the PCB surface. (Typically used in 6-layer boards and above)

Benefits: Increases wiring space;

Drawbacks: The process is costly, and generally not adopted for standard electronic products. It is only used in particularly high-end products.
