PROBLEM TO BE SOLVED: To display both an accurate creation record of defect information and a defect analysis result on a screen by using an image of an inspection object in combination with mounting location coordinate data of each component. SOLUTION: A controller 5 reads defect data on a required printed circuit board, calculates a cumulative defect occurrence number of each component, and creates chief inspection component data comprising component names, locations and mounting location coordinates of the top 10 components. Simultaneously, the controller 5 reads image data and coordinate data of the required printed circuit board from a memory part 2, and displays an image of an inspection printed circuit board on a touch monitor 4. The controller 5 creates defect data associated with a board name, a failed component name, mounting coordinates, a defect kind and a defect data input date and time according to a prescribed process, and records the created defect data into the memory part 2. In analysis, the controller 5 converts the mounting coordinates of the stored defect data in the memory part 2 into image coordinates by use of a specific expression, and displays a defect occurrence frequency display area on each the component of the image of the printed circuit board. |
