HDI PCB manufacturing provides high-density interconnect solutions with microvia, blind via, and buried via structures for compact, high-performance electronics. We deliver reliable HDI boards from prototype to mass production, supporting up to 30 layers for automotive, 5G, medical, and industrial applications.
What Is HDI PCB and Why Choose It
High-density interconnect (HDI) PCBs offer much higher wiring density than standard PCBs, using microvias, blind vias, buried vias, fine lines, and high-performance materials.
By shortening signal paths and optimizing routing, HDI PCBs create smaller, more reliable, and higher-speed electronic products for modern engineering demands.
- Pack more functions into a smaller footprint with microvia and via-in-pad
- Improve signal integrity and reduce high-speed noise
- Lower total system cost by reducing layer count
- Enhance reliability with optimized thermal and structural design
Microvia, Blind & Buried Via Structures
Our HDI PCB manufacturing uses precision laser drilling to build reliable via structures for high-density designs:
- Microvia: Laser-drilled vias down to 0.10 mm (4 mil)
- Blind Via: Connects outer layer to inner layer without full penetration
- Buried Via: Connects inner layers only, invisible on the surface
- Stacked & Staggered Vias: Advanced structures for maximum routing density
