Abstract
A conductive adhesive, such as an anisotropic conductive adhesive, comprising a population of conductive particles and a population of signal particles in an adhesive; wherein both the conductive particle population and the signal particle population have an average particle diameter of <200 μm with a coefficient of variance of <10%; wherein the signal particles are arranged to provide an indication when they are deformed to a pre-determined height; and wherein the conductive particles are arranged such that they will not fail, e.g. crack or fracture, when deformed to a height larger than or equal to the pre-determined height at which the signal particles are arranged to provide the indication.
