12 Layer 3OZ High Density Interconnect HDI PCB
♦ What is High Density PCB (HDI PCB)?
A High Density Interconnect (HDI) PCB is an advanced printed circuit board designed to accommodate more components in a smaller space by using finer traces, smaller vias, and higher connection density than traditional PCBs. HDI technology enables miniaturization, improved signal integrity, and enhanced performance in modern electronics.
♦ Key Features of HDI PCBs:
✅ Finer Trace Width/Spacing (≤ 100µm, vs. standard 150µm+).
✅ Microvias (laser-drilled, < 150µm diameter) for high-density interconnects.
✅ Blind & Buried Vias (instead of through-hole vias) to save space.
✅ Thinner Dielectric Materials (for compact layer stacking).
✅ Higher Layer Count (often 8+ layers in a slim profile).
✅ Advanced Materials (low-loss dielectrics for high-speed signals).
♦ HDI PCB vs. Standard PCB: Key Differences?
| Feature | HDI PCB | Standard PCB |
|---|---|---|
| Trace Width | ≤ 100µm (can go down to 40µm) | ≥ 150µm |
| Via Size | Microvias (50–150µm) | Through-hole vias (≥ 300µm) |
| Via Types | Blind, buried, stacked | Mostly through-hole |
| Layer Count | 8+ (with thin dielectrics) | Typically 2–12 layers |
| Signal Speed | Optimized for high-speed signals | Limited high-speed performance |
| Applications | Smartphones, wearables, aerospace | Consumer electronics, power circuits |
