Using the PanelScan Multi-Array PCB Traceability System Overview This document describes the configuration and use of PanelScan, a turnkey solution for large area imaging in electronics manufacturing and assembly applications. PanelScan is available as both a Standard one-camera solution and as a Wide two-camera solution. The PanelScan solution simplifies the error-prone and time-consuming process of capturing and associating traceability data or inspection data for multi-array printed circuit boards and component trays at the front-end assembly. PanelScan is designed to perform array-based decoding within very large line scan images.
PanelScan uses one or two Basler Racer 6K wide line scan cameras, which image a single row of pixels on a PC board as it moves under the camera on a conveyor. A special line scan line light is used to illuminate that line of the board with very bright light. As the board moves, the system builds a 6,144 x 13,824 pixel image (a 12,288 x 13,824 pixel image for Wide configuration). There are two applications involved. The first is the image acquisition application, called Basler Acquire. This software is installed automatically during PanelScan installation. Basler Acquire uses the Basler SDK to take images and place them in a Memory Mapped File or MMF.
One instance of Basler Acquire runs per camera. The second application is the PanelScan UI, which is based on Omron Microscan’s AutoVISION Software. When triggered, it reads the images from the Memory Mapped File and processes them. The output from the system is a string of all decodes placed in a .csv or .xml log file.
