HDI PCBs have a higher unit circuit density than traditional PCBs. They use a combination of buried and blind vias, as well as microvias with a diameter of 0.006 inches or less.
High-density circuit boards are PCBs with the following or more features:
There are through-holes and buried vias, surface-to-surface, at least two layers with holes, core-to-coreless structure, powerless substrate structure without power connection, core-to-coreless structure alternative
