The designer MUST be involved in the decision making for a board stackup, as the fabricator only knows his own needs, not the needs of the signals. The stack affects the way the signals flow and so can affect many electronic aspects of the functioning circuit like layer count, field spread/interference, return current, impedance control, and layer paired routing. Likewise, if the stack is not set up correctly, it will affect whether the board might warp, have a higher cost, or whether it will meet standards. In today’s higher speed designs it is critical to do this step well, so we will discuss the issues that are needed for a good stackup, both from an electronic and a manufacturability perspective.
