An overview of computer packaging architecture and electrical design

Abstract

A discussion of packaging architecture is presented to understand the requirement on the physical design of the single chip module (SCM), multichip module (MCM), printed circuit board (PCB), connector, and cable. They in turn establish the driving force for their electrical designs. The packaging architecture of midrange, mainframe, and workstation computer systems provides an insight into the requirements of the physical and electrical design of electronic packaging of the future. It is important to ensure the electrical signal fidelity throughout the interconnection to limit the switching noise and signal crosstalk, and to minimize the propagation delay due to packaging. Electrical design with these consideration for chip carrier, printed circuit boards, connector, and cables is described.<>
