Analysis techniques and notes about how yieldWerx modules support these
From ATE Test to Actionable Information- Support
For decades engineers have used STDF as the standard format for ATE test output- data logs, and yieldWerx automatically parses this format. However, with the increase in engineer’s usage of the general data record type (GDF) this usage often results in every product test program’s data log having a unique format from which you need to extract your data. Our support team can assist your company in this data extraction from STDF generated data logs using GDF record types.
Customized Data Parsing and Integration with yieldWerx
In addition, our support can create custom data parsers that can read proprietary ATE data formats. The resulting test data then integrates into Core yieldWerx as well, integrating it into the system easily. The test results can be loaded automatically into Core yieldWerx real-time basis or imported manually into Core yieldWerx.
Automating test data handling is valuable because your product may be assembled and tested at different sites. This could involve different ATEs, each likely generating slightly different data logs. Take the example of a customer (MPS); they used five different OSATs for product XYZ, resulting in a variety of unique test data logs to parse. The product volume over one quarter represented ~MMM units. With our support in extracting the data from each OSAT house MPS customer could view all the test results in a unified database found in Core yieldWerx.
Enhanced Decision-Making Through Data Visualization
Once data is loaded into the yieldWerx, the end-user can drill down the data and see the reports in the form of text as well as visually rich charts. These visualizations assist engineers to understand and pinpoint issues in the ATE data. The engineering managers and planners can read relevant reports and make decisions on the fly regarding engineering and planning priorities. They can customize the reports, set rules, and generate alerts, which maximizes their usage of Core yieldWerx as a yield management system.
Achieving Consistent Data Analysis for Actionable Insights
Customers rely upon Core yieldWerx for analyzing the data in a consistent manner that captures their operations and delivers data on which engineers and analysts can take action. Typical data to action events include identifying low-yielding lots, discerning equipment anomalies, or flagging drifts in parametric test results. Automating triggers in the yield management system allows for early notification to staff before issues become critical. It also provides guidance on where to initiate root cause investigations. These efficiency measures not only save an engineer's time, but also prevent additional yield loss, directly contributing to profitability.
Personalized Yield Management Systems for Optimal ROI
yieldWerx understands that every client has a different set of needs and this requires customization of a yield management system. For over 15 years yieldWerx has been successfully delivering customizations to its valued customer and helping them achieve minimum defects, reducing time to market and saving test time, and ultimately achieving higher ROI.
