4L 2+N+2 HDI PCB

HDI PCB are abbreviation of  high density interconnect printed circuit boards, they are characterized by finer lines, closer spaces, and more dense wiring.

For HDI boards own higher circuit density than traditional circuit boards, its designs can include smaller through holes and capture pads, and also higher connection pad density. They are widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical performance of the device.

HDI boards are applied to wide range of industries, like digital devices, smartphones and tablets, automobiles, aircraft and other vehicles products. 

HDI Board Stack-up:

1+N+1 with laser microvia and mechanical buried core via. The “1” represents “build-up” or sequential lamination on each side of the core.
i+N+i (i>=2) PCBs contain 2 or more “build-up” of high-density interconnect layers. Microvias on different layers can be staggered or stacked. Copper filled stacked microvia structures are commonly seen in challenging designs.
