What is AOI?

Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the manufacturing process because it is a non-contact test method. It is implemented at many stages through the manufacturing process including bare board inspection, solder paste inspection (SPI), pre-reflow and post-re-flow as well as other stages.

Flexible/multi-purpose AOI
Different models are suitable for multiple quality control positions on the production line, including 2D after solder paste printing
Solder paste quality inspection, component measurement before reflow soldering, process quality inspection of PCBA after reflow soldering, and inspection after wave soldering of hand plugs

Full vector algorithm, fusion logic operation, bilateral brightness boundary distance, component body tracking, OCR/OCV, brightness template matching, color distance, color extraction (RGB & HSV), brightness range, brightness deviation, minimum brightness change span, etc. 30 A variety of advanced detection algorithms.
