HIGH DENSITY INTERCONNECT – HDI PCB

 

Features of HDI PCB

1. Smaller vias and traces for higher route density and fewer layers.
2. Micro-via patterns for routing channels, potential for fewer layers.
3. Only practical way to design with multiple large BGAs having <0.4 mm pitch.
4. Lowest cost for high density boards.
5. HDI for improved signal and power integrity.
6. Newer materials available of higher performance and lower costs, which are not suitable for standard or sequential lamination.

 

HDI PCB is the best alternative to high layer-countand expensive standard laminate or sequentially laminated boards.
1. The trend is for higher pin-count and finer pin-pitch. The tipping point will occur when the >1500 pin BGAs use 0.4mm pitch.
The only way to effectively breakout and route multiple instances of these devices on a single board will be with the smaller HDI feature sizes.
2.HDI PCB currently dominates the fabrication technology for handheld and consumer electronics. For large board designs, it will continue to grow.

 

HDI PCB Structures:

  • 1+N+1 – PCBs contain 1 “build-up” of high-density interconnection layers.
  • i+N+i (i≥2) – PCBs contain 2 or more “build-up” of high density interconnection layers. Microvias on different layers can be staggered or stacked. Copper filled stacked microvia structures are commonly seen in demanding designs.
  • Any Layer HDI PCB – All the layers of a PCB are high density interconnection layers which allows the conductors on any layer of the PCB to be interconnected freely with copper filled stacked microvia structures. This provides a reliable interconnect solution for highly complex large pin-count devices, such as CPU and GPU chips utilized on handheld and mobile devices.

Advanced Capabilities:

  • Any layer HDI PCB.
  • Multilayer copper filled stacked micro via structure.
  • Stacked Microvias / Via in pad.
  • UL Recognized / Copper & epoxy hole fill / Via on hole / FCV.
  • 0.4 mm pitch BGA.
  • 3/9 mil laser via capture pad size.
  • Embedded distributed and discrete passive components.
  • Complex rigid-flex HDI products.
  • Wide material and surface finish selections.
