Patent ID: 8121394

Claim:
A method for manufacturing an electronic device, comprising: pressure-bonding a plurality of terminals of an electronic component to a plurality of electrodes formed on a surface of a transparent substrate, respectively, via an anisotropic conductive film to mount the electronic component on the transparent substrate; obtaining an image of the electrodes by imaging the transparent substrate with the electronic component mounted thereon from backside of the transparent substrate; measuring the number of indentations for each said electrode using the image of the electrode, the indentation being formed when the electrode is pressed by a conductive particle in the anisotropic conductive film; calculating an average and a standard deviation of the number of indentations per electrode throughout the transparent substrate by an indentation tester; and calculating a probability that the number of indentations per electrode is less than a reference value on basis of the average and the standard deviation by the indentation tester.
