HDI PCB

The Ultimate High-Density Interconnect Solution for Next-Gen Miniaturization

High-Density Interconnect (HDI) PCBs leverage microvias, ultra-fine traces, and advanced stacking to deliver 10× the component density of traditional boards—enabling revolutionary designs in smartphones, wearables, and AI hardware. With ≤40μm lines/spaces, laser-drilled microvias down to 50μm, and any-layer interconnects, HDI technology slashes package size while boosting signal speed and reliability.

5 Game-Changing Advantages of HDI PCBs

Extreme Miniaturization: 0.3mm BGAs & 20μm Traces: Fit 5,000+ components in smartwatch-sized spaces (e.g., 12-layer boards at 0.8mm thickness). 60% Size Reduction vs. standard PCBs—critical for AR glasses and implantable medical sensors.
Lightning-Fast Signal Integrity: <0.2dB Loss at 40GHz: Low-Dk materials (Rogers 4003C, Megtron 7) enable 112G PAM-4 SerDein AI accelerators. ±3% Impedance Control: Buried capacitance layers suppress EMI by 25dB.
Enhanced Reliability: Microvia-in-Pad Technology: Eliminate solder cracks with 100% via fill (IPC-6012 Class 3). CAF-Resistant Laminates: Survive 1,000+ thermal cycles (-55°C to 260°C).
Power Efficiency: Shorter Signal Paths: Cut power consumption 30% in 5G mmWave modules. Embedded Passives: Replace 40% of discrete components for cleaner power delivery.
Cost Optimization: Fewer Layers, Higher Function: 8 HDI layers outperform 16 standard layers—saving 25% on material costs. High-Yield Manufacturing: Laser direct imaging (LDI) achieves 99.95% defect-free microvias.
