HDI PCB Manufacturing – Microvia, Blind & Buried Via HDI Boards up to 30 Layers

HDI PCB manufacturing capabilities and technical specifications

We provide professional HDI PCB manufacturing with laser‑drilled microvias, blind vias, buried vias, and advanced stack‑ups for high‑performance, compact electronic devices. Our services include fast prototyping, controlled impedance, strict quality control, and full DFM engineering support.

What Is an HDI PCB and Why Choose It?

High‑density interconnect (HDI PCB) offers significantly higher wiring density than standard PCBs using microvias, blind and buried vias, fine lines, and thin‑core high‑performance materials.

By shortening signal paths, improving layer efficiency, and freeing routing space under fine‑pitch BGAs, HDI PCBs deliver smaller size, better signal integrity, higher reliability, and lower total system cost.

Key advantages of HDI PCB:

  • Pack more functions into a smaller footprint with microvias and via‑in‑pad
  • Improve signal integrity and reduce high‑speed noise
  • Lower layer count and reduce overall BOM cost
  • Enhance thermal performance and long‑term reliability
