Patent ID: 7919782

Claim:
An instant circuit inspection method, applied to inspect the reliability of a circuit connection of a bonding structure of two circuit substrates, comprising the steps of: providing the bonding structure comprising: a first circuit substrate having a first circuit, wherein an end portion of the first circuit comprises a plurality of first contact pads transmitting signals separate from each other; a second circuit substrate having a second circuit, wherein an end portion of the second circuit comprises a plurality of second contact pads transmitting the signals separate from each other and each second contact pad is configured to be opposite to the corresponding first contact pad for connecting the first circuit, and is divided into a circuit part and a detecting part by a gap; and an anisotropic conductive film disposed between each corresponding first and second contact pad, wherein the gap is wider than the diameter of the conduct particle in the anisotropic conductive film; the detecting part is electrically connected to the circuit part by the anisotropic conductive film and the first contact pad; and the single first contact pad is simultaneously electrically connected to the circuit part and the detecting part; performing inspection procedures to each of the second contact pads, wherein the inspection procedures comprises: inputting a signal to the circuit part of the second contact pad; measuring an output signal from the detecting part of the second contact pad; and comparing the output signal with the signal inputted, wherein the output signal and the signal inputted are of the same type.
