## What Is Any Layer HDI PCB?

[Any Layer HDI PCB](https://www.bestpcbs.com/blog/2025/11/any-layer-hdi-pcb-manufacturers-in-china-fast-delivery/)(Any Layer High Density Interconnect Printed Circuit Board) is a revolutionary PCB manufacturing technology. It utilizes laser drilling to create micron-scale microvias on all conductive layers of the circuit board, including the innermost layers, combined with an electroplating via-filling process.

This enables direct interconnection between any two adjacent circuit layers, eliminating the dependency on mechanically drilled through-holes for interlayer connections. Consequently, it breaks free from the limitations of traditional through-holes and conventional buried/blind via stacking structures in standard HDI designs, achieving the most advanced routing density and ultra-compact design capabilities currently attainable.

## How to Design Any Layer HDI PCBs?

**1. Layer Stackup and Impedance Control**

- Core Principle Upgrade: Employ dynamic stackup optimization algorithms to automatically adjust layer counts based on signal density distribution (e.g., 8-layer boards use L1-L2 signal/ground hybrid layers + L3-L6 buried capacitance layers + L7-L8 signal layers). Thin dielectric layers (30-50μm) require precise impedance calibration using 3D field solvers, targeting 50±5%Ω for single-ended signals and 90-110Ω for differential pairs, supporting over 100GHz high-frequency signal transmission.
- Impedance Formula Expansion: Introduce nonlinear material models (e.g., Debye model) to correct high-frequency effects. Microstrip impedance Z0​=εr​​87​ln(0.8w+t5.98h​) requires skin-effect correction terms, while striplines must account for coupling capacitance between adjacent copper layers. Reserve ±5% manufacturing tolerance, with differential impedance control for critical signal lines.
- Material Selection Deepening: For high-frequency scenarios, LCP (liquid crystal polymer) substrates (Dk=2.9, Df=0.002) are recommended. Medical devices require ISO 10993 biocompatibility certification, while automotive electronics select materials with matched CTE (CTE difference
