HDI means HIGH DENSITY INTERCONNECT PCBS. Owing to increase, density they provide the necessary routing solutions for large pin-count chips that are utilized in mobile devices and other high tech products.


What kinds of HDI board you can get from us?

HDI PCBs have a much higher wiring and pad connection density than traditional PCBs, due to their design constraint. The structural build up is explained below.

1+N+1 – PCBs contain 1 “build-up” of high-density interconnection layers.

 i+N+i (i ≥ 2) – PCBs contain 2 or more “build-up” of high density interconnection layers. Microvias on different layers can either be staggered or stacked up.

 Any Layer HDI – The layers of a PCB are high density interconnection layers which allow the conductors on any layer of the PCB to be interconnected freely with copper filled stacked microvia structures.

Applications of the HDI PCBs:

· Automotive Industries: Engine Control Units, GPS, Dashboard Electronics.

· Telecom Industries: Computers, Laptops, Tablets, Wearable Electronics, Internet of Things

· Military: Military Routers, COTS Boards, etc.

· Medical: 35 Micron trace space board, Pacemakers

· Semiconductors: MCM / Flip Chip / Wirebond, stacked microvias
