Abstract

The invention discloses an AOI (Automated Optic Inspection) system for inspecting a PCB (Printed Circuit Board). The AOI system comprises a scanning device and a workbench corresponding to the scanning device, and further comprises a detachable support platform, wherein the support platform is connected with the workbench, and the support platform and the workbench are located at the same height. According to the AOI system and the inspection method thereof provided by the invention, the problem that a large-size PCB cannot be supported by a table board is solved by additionally installing the detachable support platform, and the large-size PCB board is completely scanned by regional scanning. Therefore, increase of investment for purchasing a large-table-board AOI machine for detecting certain large-size circuit board is avoided, and cost is saved.

Description

technical field [0001] The invention relates to the field of circuit board manufacturing, in particular to an AOI detection system and a detection method for a printed circuit board. Background technique [0002] The full name of AOI (Automatic Optic Inspection) is automatic optical inspection, which is based on optical principles to detect common defects encountered in welding production. AOI is a new type of testing technology that has only emerged in recent years, but it has developed rapidly. At present, many manufacturers have launched AOI testing equipment. During automatic detection, the machine automatically scans the PCB through the camera, collects images, compares the tested solder joints with the qualified parameters in the database, and after image processing, checks out the defects on the PCB, and displays / labels the defects through the display or automatic signs out for repair by the maintenance crew. [0003] Existing AOI detection equipment has limited AOI...
