Higher-speed signal transmission is increasingly required on a printed circuit board to handle massive data in electronic systems. So, signal transmission loss of copper wiring on a printed circuit board has been studied. First, total signal loss was divided into dielectric loss and conductor loss quantitatively based on electromagnetic theory. In particular, the scattering loss due to surface roughness of copper foil has been examined in detail. And the usefulness of the copper foil with low surface roughness has been demonstrated.

Failure analysis (FA) is one of the key competencies in Intel. It enables very rapid achievement of world class manufacturing standards, resulting in excellent microprocessor time-to-market performance. This paper discusses the evolution of FA techniques from one generation of microprocessors to another.
