Nowadays, customers not only have requirements for the work efficiency of AOI itself, but also have higher and higher requirements for the work efficiency of AOI inspection and maintenance. After obtaining the defect coordinates of the PCB from the AOI equipment, it moves to the maintenance equipment. According to the defect coordinates, the defects are manually repaired one by one through the maintenance equipment. plenty of time

The invention discloses a PCB maintenance system and a PCB maintenance method based on false point defect detection. The PCB maintenance system comprises automatic optical detection equipment, a database server and maintenance equipment, wherein the automatic optical detection equipment is used for scanning a printed circuit board to be detected to obtain a scanned image, and comparing the scannedimage with a corresponding standard image loaded by means of the database server to construct a defect list containing defect coordinate information corresponding to preliminarily determined defectsof the scanned image; and the maintenance equipment can load the scanned image and the corresponding defect list by means of the database server, performs one-by-one re-inspection on the preliminarilydetermined defects, at each defect coordinates in the defect list, of the scanned image, deleting the defect from the defect list if the defect is re-inspected to be a false point defect, and maintaining the rest defects at the defect coordinates in the defect list corresponding to the printed circuit board. According to the PCB maintenance system and the PCB maintenance method, the false point defects detected by AOI are checked and then maintained, thereby greatly improving the maintenance efficiency.
Description
technical field [0001] The invention relates to the field of detection and maintenance of circuit boards, in particular to a PCB maintenance system and maintenance method based on false point defect detection. Background technique [0002] Nowadays, in the era of highly developed electronic industry, printed circuit board (Printed Circuit Board, referred to as PCB) has become one of the indispensable and important components of computers, electronic communications and other products. Printed circuit boards may have short-circuit or open-circuit defects during the production process, and the quality of printed circuit boards determines whether the corresponding electronic device products are qualified or not. Therefore, the quality inspection and maintenance of printed circuit boards is particularly important. [0003] In the prior art, automated optical inspection equipment (Automated Optical Inspection, referred to as AOI) is widely used in the production process of circuit...
