The part under inspection is located in the middle of the screen, highlighted by the red box. The same part from a previously saved sample board is shown in the top right corner. As the operator steps through the parts, the area of inspection is synchronized with the same area on the sample so an accurate comparison can be made. At the bottom of the screen is an overview of the PCA and the data that is imported from the pick and place machine, BOM and sample files. Control buttons at the bottom right allow the user to save and load samples, save and load archive files, and load new BOM and PCA data. Archive files are saved for QA traceability of particular production lots or of PCAs inspected.

The TABS at the bottom center contain the data imported from the pick and place machines and BOM from an ERP system. There are two more tabs that display the differences between CAD data and BOM data, as well as the sample file data

Operational Flow

The first PCA off the pick and place machine is scanned into the system. CAD data is imported and appears on the tab below the image. This data is combined instantly with mount data and BOM data and differences are highlighted in yellow. Once the fiducials are established, the operator simply steps through the CAD data with the system synchronizing the expanded image view of the part (with CAD and BOM data displayed in a box beside the part being inspected). When the Cluso system is used in conjunction with a “golden” sample board, then discrepancies between the inspected PCA and sample are also displayed in the sample differences tab. The system will track and indicate which parts have been inspected, as well as how many parts remain to be inspected.

Engineering can also notify production of upcoming changes to PCAs, such as part or revision levels, by entering notes associated with the sample board that will appear the next time that assembly is inspected.
