The 8-Layer 2+N+2 HDI Stackup – Fine-Pitch BGA PCB provides engineers and procurement managers with a robust architecture for complex, compact electronic designs. By utilising two layers of staggered microvias on each side of the core, this HDI PCB structure facilitates efficient routing for advanced Integrated Circuits (ICs) and fine-pitch Ball Grid Arrays (BGAs). It resolves strict signal integrity challenges and thermal management requirements in demanding environments.

Key Features

• 2+N+2 Stackup Architecture: Utilises two successive layers of laser-drilled microvias (blind and buried) for maximum routing density and reduced layer counts.

• Fine-Pitch BGA Support: Precisely engineered to accommodate fine-pitch components down to 0.4mm pitch without compromising electrical performance.

• Controlled Impedance: Manufactured with precise dielectric thickness and trace widths to support high-speed data transmission protocols.

• Thermal Stability: Available in FR-4 TG170 or Rogers high-frequency laminates, ensuring consistent performance under thermal stress.

• Advanced Via Technology: Incorporates staggered and stacked vias to maximise usable board space.

8-Layer HDI PCB Applications

• Telecommunications: 5G network equipment, enterprise routers, and high-speed fibre optic switches.

• Medical Devices: Compact diagnostic equipment, imaging hardware, and wearable monitoring electronics.

• Aerospace & Defence: Mission-critical navigation modules, radar systems, and secure communication devices.

• Consumer Electronics: Advanced smartphones, tablets, and smart home hubs requiring dense component packaging.
