Automatic optical inspection equipment problem point secondary calibration method

Abstract

The invention discloses a method for secondary calibration of problem points of automatic optical inspection equipment. The method comprises steps: Step S1: inputting the problem point, and judging whether the problem point inputted this time is the true point according to the preset comparison principle; Step S2: repairing the problem point determined to be the true point in step S1 or the problem point determined to be the incomplete repair in step S3; Step S3: judging whether the image printed on the screen in step S2 has been repaired according to the preset alignment principle. The invention discloses a problem point secondary verification method of automatic optical inspection equipment, if the problem point is judged to be true, a secondary calibration process is added after the repair is completed, and if the problem point is judged not to be true, screen printing is carried out for future reference to minimize the missed detection rate, the false detection rate and the false detection rate, thereby eliminating the possibility of deliberately not dealing with the problem point and / or releasing the problem point if the repair is not up to the standard.

Description

technical field [0001] The invention belongs to the technical field of circuit board production, and in particular relates to a secondary calibration method for problem points of automatic optical inspection equipment. Background technique [0002] In the field of circuit board production technology, in order to ensure the factory quality and product quality, it is necessary to inspect the circuit board. At present, the inspection process usually takes the staff to first identify the problem points through the automatic optical inspection equipment (AOI machine), and then confirm one by one on the maintenance station (VRS machine), and finally eliminate the problem points. [0003] However, the above-mentioned human-computer inspection process, the initial identification process of problem points and the elimination confirmation process after repair still require manual judgment. It should be noted that manual operation inevitably has a certain rate of missed detection, fal...

Problems solved by technology

[0003] However, the above-mentioned human-computer inspection process, the initial identification process of problem points and the elimination confirmation process after repair still require manual judgment.

It should be noted that there is a certain rate of missed detection, false detection and false detection in manual operation, and there may even be the possibility of deliberately not dealing with the problem point and / or the possibility of releasing the problem point if it is not repaired to the standard

The current inspection process is difficult to eliminate the above hidden dangers
