Title:
PTC特性を有する異方導電性接着剤
Document Type and Number:
Japanese Patent JP4482676
Kind Code:
B2
Abstract:
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.
