Blind and Buried Vias Explained
Blind vias link outer to inner layers; buried vias live entirely inside. They unlock density but add lamination cycles.
Definitions
Blind starts at a surface; buried never reaches it.
Process cost
Each via type adds lamination and registration steps.
When worth it
Use where pitch forces routing you cannot achieve with through vias.
Key Takeaways
Key Takeaways
- Blind reaches a surface; buried does not.
- Each adds lamination cycles.
- Use only when pitch demands it.
