INSTRUCTIONS: [Technical Field 3 of the Invention] Field of the Invention The present invention relates to a method and system for verifying a suspected defect in a printed circuit board. I: Prior Art 3 Background of the Invention Printed circuit boards (PCBs) are manufactured by extremely complicated manufacturing processes in which various defects occur. Typically, a printed circuit board will be manufactured with a quality control program 'which can include multiple stages' such as inspection and verification to assure its quality. This quality control program is usually executed in two steps. This first step is performed by an automated optical inspection (AOI) system, which may include a camera. In the first step, the AOI will detect the location of the suspected defect. When the 15th step is performed, a checkpoint will attempt to manually or automatically verify whether the suspected defect is a true defect. Typically, the quality control program, and particularly the verification phase, must obtain images of different regions of the PCB and different magnification (zoom) scales of the panel. 20 To date, 'capturing multiple images of different areas of the PCB and their different zoom scales requires machines that densely move the verification system, as well as densely mechanically moving the optical components to change parameters (eg, magnification) And focal length). Moving the camera itself and the optical components of the camera is tedious, time consuming, and costly. 5 201009326 There is therefore a growing need for an efficient method and system that will address these issues and provide a fast, accurate, reliable, and simple means of verifying suspected defects on printed circuit boards.
