High-Density Interconnects circuit board also called HDI PCB, which is the fastest developing technologies in PCBs, can be defined as a printed circuit board with higher wiring density than conventional pcb. It is very vital and important for some devices to reduce size and weight, and enhance electrical performance. It has wide application.It usually is used for programmed digital automatic control, such as cellphone, GPS and so on.
It can be divided into two kinds of board-blind and/or blind vias. There is our company 6 Layer PCB:
