种导电粘结剂，例如各向异性导电粘接剂，其在粘合剂中包括导电颗粒集团和信号颗粒集团；其中导电颗粒集团和信号颗粒集团均具有<200μm且变化系数<10％的平均颗粒直径；其中信号颗粒被配置为当其变形至预定高度时提供指示；其中导电颗粒被配置成当其变形至大于或等于所述预定高度的高度时不会失效，例如不会裂化或破裂，其中所述信号颗粒被配置为在所述预定高度下提供指示。 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.
