With the pitch of the parts getting tighter and the pin count of BGAs going up, there is a need to get as much routing, on as few layers as possible, into very dense areas of the board. HDI will help to accomplish this, but the technology requires some different setup and thought as to what is needed and how to accomplish it from a design perspective. First, the designer needs to understand the structure of the HDI traces and vias, and what their options and effects are to the cost and electronics involved. The presentation will go into the different possible stackup types next, and discuss ways to get signals and powers from layer to layer in the board. Then we will move on into possible patterns and grids such as via in pad, offset or swing vias to maximize fanout and routing opportunities, all the while keeping routing return, power distribution, and layer paired routing in mind. Lastly, we will talk about the benefits to other parts on the board that HDI can provide, and some information about the unique manufacturing needs of these types of boards.

HDI PCBs are printed circuit boards that feature higher wiring density per surface area than standard PCBs. As parts become tighter and pin counts of BGAs increase, it is necessary to get as much routing, on as few layers as possible, into very dense areas of PCBs. By using HDI technology, it is possible to place more components on both sides of the raw PCB.  From a design perspective, HDI technology requires different setup and thought as to what is needed and how to accomplish it. This course will provide instruction in HDI technology, covering:

  • the structure of the HDI traces and vias
  • options and effects of cost and electronics
  • options for stack up types
  • how to get signals and powers from layer to layer in the board
  • patterns and grids such as via in pad, offset or swing vias to maximize fanout and routing opportunities
  • routing return, power distribution, and layer paired routing


Discussion about the benefits HDI technology provides to other parts on the board, along with the unique manufacturing needs of these types of boards will also be covered.
