摘要： The present invention relates to an anisotropic conductive adhesive comprising an anisotropic conductive adhesive combined with a crystalline polymer to realize anisotropic conductivity and PTC (Positive Temperature Coefficient) characteristics at the same time. The anisotropic conductive adhesive having PTC characteristics according to the present invention comprises an insulating adhesive component and a plurality of conductive particles dispersed in adhesive component, in which the insulating adhesive component comprises a crystalline polymer. Since the anisotropic conductive adhesive according to the present invention includes a crystalline polymer, when temperature rises and the volume expands, electrical resistance is rapidly increased, whereby current flow is intercepted resulting in blocking current, providing PTC characteristics acting as a switch. Thus, it shows circuit protection function as well. Accordingly, it is possible to intercept a circuit upon occurrence of excess current without using a separate element for circuit protection such as PTC thermistor.

摘要： The present invention discloses an anisotropic conductive adhesive comprising an insulating adhesive component and a number of conductive particles dispersed in the insulating adhesive component, wherein the insulating adhesive component contains a crosslinked rubber resin. The anisotropic conductive adhesive of the present invention prevents exfoliation of an adhesive or reduction in adhesive strength of circuit by minimizing its the heat-contraction occurring in the process of a polymerization or a hardening reaction when connecting micro-circuits, whereby a short circuit between adjacent electrodes can be prevented when connecting the circuits, and excellent connection reliability according to a long-term use is achieved.
