Abstract

An anisotropic conductive adhesive is a material which comprises a highly insulating adhesive and electroconductive particles uniformly dispersed therein, and such a material is used in electronic components for the purpose of electrical connection between electrodes that face with each other, insulation between adjacent electrodes, or fixing. Conventional anisotropic conductive adhesives exhibited low durability in terms of creep test, and it was therefore difficult for conventional anisotropic conductive adhesives to attain stable circuit resistance. Disclosed is a non-reactive anisotropic conductive adhesive which comprises (A) a polyamide elastomer, (B) a powder composed of spherical electroconductive particles, and (C) a solvent and which exhibits excellent creep characteristics and conducting properties.

Description

technical field [0001] The present invention relates to an anisotropic conductive adhesive. Background technique [0002] Anisotropic conductive adhesive (hereinafter also referred to as ACP) is a material in which conductive particles are uniformly dispersed in a highly insulating adhesive. It is intended to be used for electrical connection and adjacency between opposing electrodes of electronic components. Insulation and fixation between electrodes. ACP containing a solvent is printed on a flexible printed circuit (hereinafter referred to as FPC) and heated and dried to form a coating film of ACP on the FPC. An FPC including a coating film is known as a heat seal connector (heat seal connector, heat press paper) component (Japanese Patent Application Laid-Open No. 60-170177). After the electrode portions of the display element and the electrode portions of the thermocompression-sealed connector member are superimposed on each other, the respective electrodes can be sele...
