Isotropically Conductive Adhesives (ICAs)

  • Chapter
  • First Online:
Electrical Conductive Adhesives with Nanotechnologies

Abstract

Isotropic conductive adhesives, also known as “polymer solder,” are composites of polymer resin and conductive fillers. The conductive fillers provide the composite with electrical conductivity through contact between the conductive particles. With increasing filler concentrations, the electrical properties of an ICA transform it from an insulator to a conductor. Percolation theory has been used to explain the electrical properties of ICA composites. At low filler concentrations, the resistivity of ICAs decreases gradually with increasing filler concentration.
