ANISOTROPIC CONDUCTIVE FILM

摘要

There is provided an anisotropic conductive film that contains a radically polymerizable substance, a polymerization initiator that generates a radical by heating, a phenoxy resin having a molecular weight of 30,000 or more, and electrically conductive particles, wherein the anisotropic conductive film has a DSC exothermic onset temperature of 100°C or lower and a DSC peak temperature of 120°C or lower when measurement is performed at a rate of temperature increase of 10 °C/min. The film is capable of establishing a sufficient electrical connection between circuit boards by heating at a low mounting temperature for a short time and is free from problems such as a reduction in connection performance with time in a high temperature and humidity atmosphere.
