Shielded Tracks on a Printed Circuit Board

Open publisher page 0 citations

Abstract

Fully shielded tracks can be embedded in multilayer printed circuit boards by a novel manufacturing technique. The paper presents a numerical analysis of the influence of dimension tolerances on the characteristic impedance. For partly shielded tracks the coupling between tracks and the environment is studied as well. The analysis relies on a two-dimensional approach, using Conformal Transformations and a static Method of Moments.
