HDI (High Density Interconnector) board, which is high density interconnect boards ,it is one kind of a relatively high density circuit boards that using blind and buried vias micro line technology . Containing the inner line and the outer line,using drilling and hole metallization process to achieve link function between the internal layers of the circuit. As electronic products to develop high-density, high-precision, corresponding to the circuit board to made the same requestment. And improving the density pcb most effective way that is reduce the number of through-holes, and accurately set blind hole, buried hole can achieve this requirement, so it HDI boards should be produced.
