Patent ID: 8047381

Claim:
A method for manufacturing an anisotropic conductive adhesive containing a plurality of conductive grains that are needle-shaped, the method comprising: dispersing the grains using a disperser; orienting the dispersed grains, wherein the orienting includes using a flow passage for orienting each of the dispersed grains in a longitudinal direction of each grain while spacing the grains apart from one another in the longitudinal direction; measuring, by a measurer, the length of each of the grains oriented in the longitudinal direction; separating, by a separator, grains having a predetermined length from the dispersed grains based on data related to the lengths of the measured grains; forming the anisotropic conductive adhesive containing the grains having the predetermined length; and supplying to the disperser, by a reprocessor, grains other than the grains having the predetermined length.
