H2: What Are Blind Vias & Buried Vias?

In multilayer PCBs, blind vias and buried vias are advanced interconnect technologies used to create high-density designs without increasing board size.

Blind Vias

Definition: A blind via connects an outer layer of the PCB to one or more inner layers but does not pass through the entire board.
Visualization: Imagine a “blind hole” drilled from the surface to a specific internal layer.
Key Benefit: Saves space compared to through-hole vias, ideal for compact designs like smartphones or wearables.

Buried Vias

Definition: A buried via exists entirely within the inner layers of the PCB and does not reach the outer surfaces.
Visualization: Think of it as an “invisible” connection sandwiched between layers.
Key Benefit: Improves signal integrity by reducing stub effects in high-frequency circuits.

Comparison to Standard Through-Hole Vias

Feature	Blind Via	Buried Via	Through-Hole Via
Visibility	Surface to inner layer	Inner layers only	Full board penetration
Use Case	Space-saving, HDI	Complex multilayer designs	Cost-effective, simple boards
Cost	Higher (laser drilling)	Highest (sequential lamination)	Lowest
