AOI (Automatic Optical Inspection)

AOI (Automated Optical Inspection) stands for Automatic Optical Inspection. It is a device that detects common defects encountered in welding production based on optical principles. AOI is a new type of testing technology, but it is developing rapidly. Many manufacturers have launched AOI testing equipment. When automatic detection, the machine automatically scans the PCB through the camera, collects the images, compares the tested solder joints with the qualified parameters in the database. After image processing, the defects on the PCB are checked out, the defects are displayed / marked by the display automatic marks Come out for repairs.

Using high-speed high-precision visual processing technology to automatically detect various mounting errors soldering defects on PCB boards. PCB boards can range fine-pitch high-density boards to low-density large-size boards, can provide online inspection solutions to improve production efficiency welding quality. By using AOI as a tool to reduce defects, find eliminate errors early in the assembly process to achieve good process control. Early detection of defects will avoid sending bad boards to subsequent assembly stages, AOI will reduce repair costs avoid scrapping non-repairable circuit boards.

main feature

1) High-speed detection system

related to PCB board mounting density

2) Fast convenient programming system

Graphical interface

Automatic data detection using placement data

Fast editing of inspection data using component database

3) Use rich dedicated multi-functional detection algorithms binary gray level optical imaging processing technology for detection

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

5) Check the electricity by marking directly on the PCB with ink using graphic error indication on the operation display.
