AOI’s obvious benefit is its ability to spot defects in boards or subassemblies coming down a production line, so any defective units are captured and removed for rework before being shipped to a customer or integrated into a larger system.
Yet AOI systems also have huge potential beyond the obvious - they collect large volumes of data that can be used to steadily improve process yield over a longer period of time. However, for this data to become effective, it must be analysed and presented to users as information which is relevant, easy to understand and easy to use in improving their line or process.
VuData, Cupio Yestech Europe’s recently announced statistical process analyser software package, provides this easy link; acting on data generated by a YESTECH AOI installation to produce information on which management decisions can be made, both for short term corrective actions and longer-term yield improvement strategies.
VuData stores data with all faults related to assembly numbers, board serial numbers, system operator and time. Performance data in terms of line speeds, timing and throughput is also collected. Comprehensive reports can be generated, showing yield rates in both board and opportunity format, as well as current and historical failure rates with types and trends. Management reports are also available for inspection and review timing, false and genuine fault rates and other line metrics.
Live charting directly shows yields and part failure rates, with common failures and rankings. Additionally, these charts generate performance alarms, which can be emailed directly to any staff that should be alerted. Information may be exported to Excel, pdf, jpg or other formats for external use. Fail pictures are presented in a fault picture viewer, and any data can be used to generate live charts, graphs and reports as circumstances demand. This allows feedback from the production line or rework area to be fully analysed, and actionable results generated in real time.
AOI performance can be tracked through reports related to time, user, board, fault, false call, assembly, job and serial numbers. Data can be searched, sorted, filtered and grouped without need for external software. Longer term trends can be spotted, and corrective action taken, through VuData’s analysis and presentation of statistical information including part, lead and solder fail statistics, and fault classification statistics. VuData also provides yield and throughput monitoring as well as other management statistics.
“VuData is a software package that provides its users with both immediate and longer-term benefits” commented Andy Bonner, CEO of Cupio Yestech Europe, “Alarms can be immediately raised if fault levels become excessive, and quick feedback is provided for first pass yields. Current and historical production status can always be viewed by graphics and text reports which are easy for users to format and understand. Trends and statistical data are equally as easy to access, format and present, giving management the information they need to make longer term process and yield improvements.”
