The Hybrid HDI PCB Stackup from PCBSYNC delivers an engineered material solution for complex multi-layer boards requiring both high-frequency performance and structural rigidity. By combining low-loss Rogers dielectric layers with standard FR4 substrates, this build-up board optimizes signal integrity where needed while managing overall production costs. This advanced integration is vital for hardware engineers and procurement managers developing next-generation wireless communications, radar systems, and high-speed computing devices.
Key Features of the Hybrid HDI PCB Stackup
-
Material Integration: Combines Rogers core materials (e.g., RO4003C, RO4350B) with high-$T_g$ FR4 prepreg and cores.
-
Advanced Interconnects: Utilizes laser-drilled blind and buried microvias to maximize routing density in an HDI PCB architecture.
-
Layer Count Capabilities: Available from 4 to 24+ layers with customizable build-up options (1+N+1, 2+N+2, and any-layer ELIC).
-
Controlled Impedance: Tight tolerance control down to $\pm5\%$ for critical high-speed differential pairs and RF microstrip lines.
-
Surface Finish Options: ENIG, ENEPIG, and Immersion Silver to support fine-pitch BGA components and wire bonding.
-
Compliance Standards: Manufactured in accordance with IPC-A-600 Class 2 or Class 3, and certified to ISO 9001, ISO 13485, and IATF 16949.
Applications
-
Telecommunications: 5G base stations, MIMO antennas, and high-frequency microwave backhaul links.
-
Aerospace & Defence: Compact radar modules, guidance systems, and satellite communication transceivers.
-
Medical Technology: High-resolution imaging equipment and real-time diagnostic sensors.
-
Automotive: Advanced Driver Assistance Systems (ADAS) and 77GHz automotive radar boards.
