CIRCUIT BOARD AND APPARATUS FOR CHECKING THE DEFECT OF CIRCUIT BOARD

摘要

PURPOSE: A circuit board and a failure processing apparatus thereof are provided to improve detection accuracy of a bad cell by printing a short wiring on a major wiring of the bad cell using an ink-jet printer method. CONSTITUTION: A bad cell detection unit(210) detects a bad cell among a plurality of cells. The bad cell detection unit creates coordinate data of the bad cell. A bad cell display unit(230) shorts one and more bad cells at a wiring pattern of the bad cell by printing ink with an ink-jet printer method based on the coordinate data of the bad cell. The ink uses different ink with the wiring pattern of the bad cell. A bad cell determination unit(250) classifies a final bad cell about the bad cell in which ink is printed.
