Isotropic conductive adhesives in electronics
J.E. Morris, Portland State University, USA
Abstract:
Isotropic conductive adhesives are metal/epoxy composites with high loading beyond the percolation threshold for electrical conduction. The primary reliability issues are impact resistance and galvanic corrosion of the contacts, among others. Nanoparticles and carbon nanotubes are beginning to be incorporated into the materials, for improved performance.

4.1 Introduction
There are two primary categories of electrically conductive adhesives (ECAs): isotropic conductive adhesive (ICA) and anisotropic conductive adhesive (ACA), with the latter dividing ...
