Production Line

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)

Visual inspectionVisual inspection is a common method of quality control, by using either or all human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment to ensure that the manufactured products being made to meet the quality requirements.
