Level 2 HDI PCB
The Level 2 HDI PCB technology is an improvement on the Level 1 HDI PCB technology. It includes two forms of laser blind via drilling directly from the surface layer to the third layer, and laser blind hole drilling directly from the surface layer to the second layer and then from the second layer to the third layer. The difficulty of the Level 2 HDI PCB technology is far greater than the Level 1 HDI PCB technology.

8 layers Of Double Via Level 1 HDI PCB
The figure below is 8 layers of level 2 cross blind vias , this processing methodand the above eight layers of second order stack hole , also need to play twolaser perforations . But the perforations are not stacked on top of each othermaking it much less difficult to process.
