High Density Interconnection,shorted as (HDI) PCB, is a kind of (technology) for the production of printed circuit boards. It is a circuit board with relatively high circuit distribution density using micro blind via and buried via technology. Adopting the structure of Stripline and Microstrip, multi-layering becomes a necessary design. In order to reduce the quality problem of signal transmission, insulating materials with low dielectric constant and low attenuation rate are used. To meet the miniaturization and arraying of electronic components, the density of circuit boards is constantly increasing to meet the demand.

HDI (High Density Interconnection) circuit boards usually include laser blind vias and mechanical blind vias; general through buried vias, blind vias, stacked vias, staggered vias, cross blind buried, through vias, blind via filling plating, fine line small gaps, The technology of realizing the conduction between the inner and outer layers by processes such as micro-holes in the disk, usually the diameter of the blind buried is not more than 6 mils.
