AOI (Automatic Optical Inspection) SMT PCBA Quality Control + Fl...



https://www.cstpcb.com
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-reflow as well as other stages. .(Wikipedia)

AOIs for a PCB board with components may inspect the following features:

Area defects
Billboarding
Component offset
Component polarity
Component presence or absence
Component Skew
Excessive Solder Joints
Flipped component
Height Defects
Insufficient Paste around Leads
Insufficient Solder Joints
Lifted Leads
No Population tests
Paste Registration
Severely Damaged...
