Overview

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.

Specifications

PanelScan Integration Guide Specifications PanelScan is available in two configurations: Standard and Wide . • PanelScan Standard – PanelScan Standard uses a single 6,144-pixel-wide line scan camera. When the camera is placed at the specified distance from the part as shown in the drawing below, it has a field of view of 250 mm (10”) wide and can read symbols up to this panel width. • PanelScan Wide – PanelScan Wide uses two 6,144-pixel-wide line scan cameras side-by-side with a 1 inch overlap to cover up to 450 mm (18”) of panel width. Both PanelScan Standard and PanelScan Wide cover a panel length of up to 520 mm within a field of view of 570 mm (22.5”).

• X Resolution – At the specified distance, the camera has a resolution of 0.00163” per pixel, or 1.63 mils . • Y Resolution – PanelScan does not use an encoder to trigger each row of pixels in the image. Images are captured in a time-based mode where each line is acquired within a certain “exposure” time. The speed of the conveyor must be matched to the X Resolution of the system to make them both even. When the speed is matched to the X Resolution, a circle will show with an even width and height.

Note that the lack of an encoder makes the system more economical and easy to set up, but it also means that the panels must be moving at a constant speed under the PanelScan camera and they must not stop until the full board is read. • 1D Symbol Reading Capability – With this resolution, the system is capable of reading high quality 1D symbols down to 3.3 mils with 2 pixels across a thin bar. Note that the system is able to read at this resolution for two reasons: the first is that it uses a high quality lens with a very good MTF ratio, and the second is that it uses a Rect Warp to magnify symbols by 200% before decoding, which helps the algorithm to decode.

Symbols must be of very high quality to be read at these small sizes. Performance on DPM marks will be slightly lower. • Data Matrix Reading Capability – With this resolution, the system is capable of reading high quality Data Matrix symbols down to 5 mils with 3 pixels per cell. Note that the system is able to read at this resolution for two reasons: the first is that it uses a high quality lens with a very good MTF ratio, and the second is that it uses a Rect Warp to magnify symbols by 200% before decoding, which helps the algorithm to decode. Symbols must be of very high quality to be read at these small sizes. Performance on DPM marks will be slightly lower.

Required Hardware

PanelScan Integration Guide Required Hardware The PanelScan kit consists of either one or two 6K Basler Racer cameras connected to an Intel NIC card on a PC. PanelScan also includes either one or two red or white line scan lights based on Omron Microscan’s NERLITE MAX 300. PanelScan requires a custom trigger provided as part of the kit, and also requires a 24V power source split out to the cameras, lights, and trigger. Several variations of the full PanelScan kit are shown in the tables below. The PC and mounting must be provided by the user. 4 Copyright © 2019 Omron Microscan Systems, Inc.

Hardware Configuration and Wiring

PanelScan Integration Guide Hardware Configuration and Wiring Trigger and power wiring must be completed as shown below. A single 24 VDC power source can be used to power all elements of the system. A terminal block is provided with the system to aid in the wiring of all components. The diagram below shows wiring for the Standard system. For the Wide system, cables 3 , 4 , 5 , and 6 are duplicated and should be wired in parallel to power ( 8 ), to the trigger ( 9 ), and to the PC NIC card. Note: Hardware configuration and wiring are the same for all Standard and Wide configurations. 5 Copyright © 2019 Omron Microscan Systems, Inc.
