Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] At present, when the Defect Mapping system tracks the location information of defective units, the management of the lot unit panel number (panel) is changed to the defects of the panel number (panel), strip number (strip) and unit (PCS unit) In this way, the defect location can be directly tracked to the unit, which greatly improves the accuracy and effectiveness of defect tracking. CAM engineers need to create center file drilling files for each type of circuit board, and make the machine automatically align and find out the printing position according to the coordinates of the positioning...
