Advantages of HDI circuit board
1. It can reduce the cost of PCB: when the density of the PCB increases beyond the eight-layer board, it is manufactured with HDI, and the cost will be lower than the traditional complex lamination process.
2. Increase line density: interconnection of traditional circuit boards and parts
3. Conducive to the use of advanced construction technology
4. Has better electrical performance and signal accuracy
5. Better reliability
6. Can improve thermal properties
7. Can improve radio frequency interference/electromagnetic wave interference/electrostatic discharge (RFI/EMI/ESD)
8. Increase design efficiency
HDI is the abbreviation of High Density Interconnector, which is a (technology) for the production of printed circuit boards. HDI is a compact product designed for small volume users.

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.
