The Buried + Blind Via HDI PCB delivers superior routing density and thermal performance for complex, space-critical electronic designs. By utilizing a combined microvia stackup, this high-density interconnect board allows engineers to interconnect multiple layers without consuming valuable surface real estate. It is specifically engineered for high-speed digital designs, RF modules, and fine-pitch BGA components where structural integrity and signal clarity are paramount.
Key Features of our HDI PCB Stackup
-
Combined Microvia Architecture: Utilizes laser-drilled blind vias and mechanical buried vias to maximize routing density across multi-layer designs.
-
Advanced Materials: Available in High-Tg FR-4, halogen-free materials, and low-loss high-speed laminates (such as Rogers or Megtron).
-
Fine Line and Space: Supports trace widths and spacing down to 3 mil (75 µm) for high-density BGA escapes.
-
Via-in-Pad Technology: Resin-filled and copper-capped vias (POVH) to optimize thermal dissipation and save surface area.
-
Compliance & Quality: Manufactured in accordance with IPC-A-600 Class 2 or Class 3 standards.
High-Density Interconnect Applications
-
Telecommunications: 5G network modules, high-speed routers, and switching systems.
-
Computing & IoT: Ultra-thin wearables, compact IoT gateways, and high-performance computing (HPC) motherboards.
-
Medical Devices: Handheld diagnostic equipment, implantable monitors, and high-resolution imaging systems.
-
Aerospace & Automotive: ADAS radar modules, engine control units (ECUs), and avionics telemetry boards.
