WebFeb 22, 2024 · Optical inspection is the best method since it can identify opens, shorts, damages, debris, and cold solder. Through careful observation, one can identify any signs of corrosion, wear, or tears on the pins quickly and easily. This technique also detects abnormalities like discoloration or misalignment. WebOptical methods are based on how the sample acts toward electromagnetic radiation. The absorption or emission of radiant energy, the bending of radiant energy, the scattering of …
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… WebAug 1, 2009 · Three different 2D optical inspection methods will be reviewed in relation to how well workmanship can be assessed, with the advantages and disadvantages of each method compared.
