What is Microvia HDI PCB?

 

A Microvia HDI PCB (High-Density Interconnect Printed Circuit Board) uses laser drilling to create micro-blind vias (Microvias) with diameters typically ≤0.1 mm, enabling high-speed signal or power interconnections between adjacent layers. Compared to traditional multilayer boards, HDI PCB with Microvias delivers significant improvements in routing density, signal integrity, and space utilization.

80–100 μm (advanced equipment can achieve 40–50 μm)
Aspect Ratio
0.6:1 to 1:1
Manufacturing Method
Laser drilling + resin plugging + copper electroplating
Applications
High-pin-count BGAs, fine-pitch packages, high-speed signal transmission

 

Core Advantages

 

01

 

High-Density Routing Micro-blind vias allow shorter, straighter traces, reducing signal delay and crosstalk, and supporting 0.2 mm pitch BGA packages.
02

 

Thin and Lightweight Design By minimizing through-hole stubs and optimizing the stack-up, Microvia PCB designs can significantly reduce board thickness and weight while maintaining mechanical strength.
03

 

Excellent Electrical Performance Precise impedance control ensures compatibility with high-speed interfaces such as DDR, PCIe, and 5G RF.
04

 

High Reliability Resin plugging and copper filling processes ensure via wall integrity, improving solder joint stability and thermal cycle performance.

 

Design and Process Key Points

 

Stacked vs. Staggered Designs

  • Staggered: Lower cost, higher reliability, suitable for most designs
  • Stacked: Space-saving, ideal for extreme density, but with higher cost and process complexity

HDI Structure Types (IPC-2226 Standard)

 

  • Type 1: One-step lamination + laser drilling
  • Type 2: Two-step lamination + buried vias + laser drilling
  • Type 3: Three-step lamination + multiple laser drilling
  • ELIC (Any Layer HDI): Any-layer interconnect, suitable for extreme miniaturization

 

Material Selection High-Tg FR-4, Rogers high-speed materials, and hybrid laminates - customized to meet specific application requirements.
