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.
