AOI inspectionAutomated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) 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 because it is a non-contact test method. 

3D Automated Optical Inspection (AOI)

SPI InspectionSolder Paste Inspection (SPI) is an automated 3D optical inspection performed immediately after the solder paste is printed onto the PCB. It precisely measures the volume, height, and alignment of the paste to detect printing defects early. This proactive check prevents soldering issues in subsequent stages, significantly improving production yield and reducing rework.
