The Buried Via HDI PCB delivers efficient inner-layer routing for dense, multi-layer circuit designs. By connecting internal layers without breaking the outer surface, this board architecture allows engineers to maximise component placement and minimise the overall board footprint. It is built specifically for hardware developers and engineers designing complex electronic systems where space and signal integrity are critical.

Key Features of the Buried Via HDI PCB

• Inner-Layer Routing: Dedicated buried vias connect internal layers (e.g., L2 to L3) without occupying outer layer space.

• Advanced Miniaturisation: Reduces layer count and overall board thickness while increasing routing density.

• Enhanced Signal Integrity: Shorter via paths minimise parasitic capacitance and inductance for high-speed digital signals.

• Material Compatibility: Available in FR4, Rogers, and polyimide substrates to meet specific thermal and electrical parameters.

• IPC Class Compliance: Manufactured to strict IPC Class 2 or IPC Class 3 standards for reliable performance.

Applications

• Telecommunications infrastructure and 5G networking equipment

• Aerospace and military control systems

• Advanced medical diagnostics and imaging devices

• High-performance computing (HPC) and enterprise servers

• Compact IoT devices and industrial wearables
