Abstract
An anisotropic conductive material contains low melting point electrically conductive particles in a thermosetting resin. The low melting point particles have a solidus temperature of at least 125° C., a peak temperature of at most 200° C., and a temperature difference between the solidus temperature and the peak temperature of at least 15° C. The maximum particle diameter of the low melting point particles is smaller than ¼ of the spacing between adjoining conductors atop which the anisotropic conductive material is to be disposed.
