AOI equipment introduction

      The full name of AOI is automatic optical inspection, which is a device that detects common defects encountered in welding production based on optical principles. AOI is a new type of testing technology emerging, but it is developing rapidly, and many manufacturers have launched AOI testing equipment. When automatically detected, it uses the camera to automatically scan the PCBA and collect images. Test solder joints are compared with the qualified parameters in the database, and PCBA defect inspection through image processing and display defects / markers AOI as a tool to reduce defects through the use of display or automatic marking during assembly.

Features of AOI

• High-speed inspection system: It has nothing to do with the density of PCB boards

• Fast and convenient programming system: conduct under the graphical interface, use the post data to automatically perform data detection, and the component database to quickly edit the detection data

• Use rich special multi-function detection algorithms and binary or gray-level optical imaging processing technology for detection

• Automatic correction of the detection window according to the instantaneous change of the detected component position to achieve high-precision detection

• Check the detection of electricity by marking it directly on the PCB with ink or graphically indicating it on the operation display
