Abstract

A method is described to inspect all drilled/blind holes on a circuit panel in an economical time/cost way. In accordance with the new method, a computer vision system employs image processing techniques to inspect all holes, including blind holes, for location, diameter, and presence/absence. The system performs this inspection in less time than required to do partial inspection manually, and eliminates operator error/subjectivity. A key feature of this arrangement is its high pixel processing rate regardless of what type of manipulation is occurring. This machine can handle various sizes of panels. All inspection data can be downloaded from the host so no teaching of individual panel types is necessary. Inspection data can also be uploaded to the host for archiving or analysis.
