The HDI PCB is the short form of High-Density Interconnect Printed Circuit Boards.
It has been constructed by using HDI technology for a compact and reliable PCB design.

It characterizes the high-density attributes including laser micro vias, fine lines as well as the high performing materials.

The traditional PCBs are covered with copper throughout the inner and outer layers ,
Where as the HDI PCBs are incorporated with multi-layers of copper filled with stacked micro-vias.

It creates a structure enabling complex interconnections to provide necessary routing solutions.
The high tech applications are utilizing the advantages of the functional strategy of the HDI PCB to construct the large pin-count chips.
