Teradyne’s Assembly Test Division has introduced the Optima 7210 optical inspection system for post-placement, in-line defect detection and process measurement. This machine vision system replaces user judgment with built-in knowledge of SMT process and variation compensation, to enable the completion of production-ready programs reportedly in just one hour. This can shorten manufacturing cycle-times, time to first product validation, and improve prototype quality. Based on configural recognition and image analysis technology, the system delivers non-contacting inspection with rapid programming, vast reductions in false flag rates, and the elimination of program maintenance required to resolve them. A component of this technology, an image compensation software, builds process knowledge and variation awareness into the image analysis, automatically compensating for normal variations in board assembly, and eliminating constant program modification. Configural recognition technology provides the flexibility to compensate for normal variation immediately, to get coverage for rapid changeover lines and consigned lot manufacturing. The supplier claims that it has also the capability to be an alternative in high-volume manufacture, where in-circuit testing is not possible or not economical. The instrument can also check for placement defects, while providing in-line monitoring for process trends. Other highlights are: measurement vehicle for manufacturers implementing 6-sigma practices; built-in compensation for normal board and process variations during program and runtime; internal SMT process knowledge displaces user judgment and skill requirements; production-ready programs developed with as few as one sample; less than 20 ppm false flag rates achievable.
