The sequential lamination buried via HDI PCB is engineered to meet the demanding routing constraints of modern, micro-miniaturised electronics. By utilizing multiple press cycles to isolate buried vias within internal layers, this multilayer board configuration frees up valuable surface real estate for high-pincount components such as fine-pitch BGAs. It serves as the backbone for complex architectures where standard multilayer tracking cannot support the required interconnection density or thermal dissipation.

Key Features of Sequential Lamination Buried Via HDI PCB

• Advanced Multilayer Build: Available from 4 to 32+ layers with precise sequential lamination cycles.

• Microvia Architecture: Blind and buried via structures paired with stacked or staggered via configurations.

• Premium Substrates: High-Tg FR-4, halogen-free materials, and low-loss high-frequency laminates (e.g., Rogers, Panasonic Megtron).

• Fine Line and Space: Ultra-fine trace widths and spacing down to 3 mil (0.075 mm) for high-density interconnects.

• Surface Finishes: ENIG, ENEPIG, Immersion Silver, and OSP for optimal solderability and coplanarity.

• Strict Quality Standards: Fully compliant with IPC Class 2 and Class 3 requirements.

Applications

• Telecommunications: High-speed routers, 5G base stations, and network switching systems.

• Computing and Storage: High-density server motherboards, solid-state drives (SSDs), and AI accelerator cards.

• Aerospace and Avionics: Compact flight control systems, radar modules, and telemetry equipment.

• Medical Devices: Handheld diagnostic tools, implantable telemetry units, and advanced imaging systems.
