Abstract :
Cyclic mechanical shear testing of isotropic conductive adhesives (ICAs) at ambient temperature reveals both viscoelastic behavior and a reproducible stress plateau. The failure mechanism is typically adhesive, rather than cohesive. Tentative explanations of the viscoelasticity and plateau are offered in terms of filler particle movement and structural layering within the epoxy matrix.
