Can Conductive Adhesives With Nanoparticles Beat Commonly Used Electrically Conductive Adhesives Without Nanoparticles

摘要

This paper deals with electrically conductive adhesives (ECA's) with isotropic properties (ICA's) and describes the way of improving the quality parameters of such electrically conductive joint. This paper discusses the advantages and disadvantages of nanoparticle addition into commonly fabricated electrically conductive adhesive. Electrical parameters of ICA joints before and after mechanical, humid and humid-heat stress is applied, are observed. Standard controlling and evaluating principles for ECAs are based on resistance measurement of a joint; this paper shows that nonlinearity evaluation is more sensitive. For some applications, linearity might have crucial importance and an absolute size of resistance might not be so crucial. Our previous work proves that nonlinearity might not just be more sensitive but that it also does not have to progress in the same way as the resistivity (Busek, D. and Mach, P.).
