发明名称 Connecting an integrated circuit on a surface layer of a printed circuit board
摘要 Techniques for optimizing application specific integrated circuit (ASIC) and other IC pin assignment corresponding to a high density interconnect (HDI) printed circuit board (PCB) layout are provided. Applying the techniques described herein, pin assignments may be systematically and strategically planned, for example, in an effort to reduce the PCB layer count and associated cost, increase signal integrity and speed, reduce the surface area used by an ASIC and its support circuitry, reduce plane perforations, and reduce via crosstalk when compared to conventional designs with an ASIC mounted on a multilayered PCB.
