3D PCB architecture for next generation high speed interconnections

Purpose – To review the challenges confronting the electronics interconnection industry as it transitions into the gigahertz frequency range and to describe novel prospective solutions designed to circumvent the problems by means of alternative interconnection architectures while remaining within the confines of the existing manufacturing infrastructure.Design/methodology/approach – The paper has been written in a manner so as to provide first a brief review of the history of interconnections as background reference, providing access and understanding to a broader readership of the significance of the area of investigation. From there, the paper describes the problems facing electronic circuit manufactures relative to the serious matter of assuring signal integrity of high speed interconnections. It then goes on to describe a general class of prospective solutions, which can be implemented through simple architectural changes in design and manufacture. Finally, the paper describes a prototype system which...
