Abstract
A system for inspection components that are sealed within tape is provided. The system includes a light source that can illuminate the components through a tape layer. A polarizer is used to polarize light from the light source, the components, and the tape layer, so as to reduce glare and reflected light. An image system receives light from the polarizer and stores image data for each component.
