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​​?​

♦ ​​​​Types of HDI PCBs​​​​:

1. 1. ​​1+N+1​​ – Single HDI layer (microvias on outer layers).
   2. ​​2+N+2​​ – Two HDI layers (stacked microvias).
   3. ​​3+N+3​​ – Three or more HDI layers (ultra-high density, used in advanced chips).
   4. ​​Any-Layer HDI​​ – Microvias can be placed anywhere (used in smartphones like iPhones).
