Optical inspection methods
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 bar… WebSep 1, 2014 · This study presents an optical inspection system for detecting a commercial point-of-care testing product and a new detection model covering from qualitative to …

WebMar 4, 2024 · Non-optical Defect Inspection Technologies. Non-optical inspection techniques, those not involving any kind of optical probing, such as KOH etching and TEM, have been widely used for characterizing the quality of SiC wafers. These methods are relatively mature and precise to inspect defects on SiC wafers. WebNon-destructive testing is a valuable technique used by many industries to evaluate the properties of a material, component, structure or system without causing any damage. There are various types of NDT such as visual inspection, radiography, ultrasonic testing, magnetic particle testing and penetrant testing.
WebUnderstanding Surface Quality Specifications. This is Sections 9.1 and 9.2 of the Laser Optics Resource Guide.

WebThis method is called automated optical inspection (AOI). An AOI system conducts an inspection using several light sources and one or more still or video cameras. The light sources light up the board from various angles. The cameras then take still images or video of the board, compiling them to create a complete picture of the unit.
