Abstract: PURPOSE: A method for testing an open/short state of an electrode is to facilely confirm whether the electrode on a board is opened or shorted, thereby finding a failure of the board at an early stage. CONSTITUTION: A method for testing an open/short state of an electrode comprises steps of applying a power source to a plurality of electrodes on a board, detecting a temperature of each electrode with a temperature sensor and determining the open/short state of each electrode. In the method, a conductive rubber plate(10) is mounted at both ends of each electrode on a pad of the board so that the electrodes are commonly connected with the power source. When the power source is exerted on each electrode, heat is generated from each electrode by a resistance of each electrode. If the heat is not detected at an electrode line in which the power is applied, it is determined that the electrode is opened. If the heat is detected at an electrode line in which the power is not applied, it is determined that the electrode is shorted with other adjacent electrode.
