Optical inspection methods

WebAOI is an automated visual inspection methodology used primarily to test for defects in printed circuit board assemblies (PCBAs). AOI autonomously scans PCBAs with cameras and detects two types of failures: 1. catastrophic failures, such as missing components, and 2. quality failures, such as misshapen fillet or components that are skewed. 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 …
