Aerospace and Defense Applications
Suppliers for aerospace and defense applications create devices at low volumes (e.g., hundreds to ten thousands units per year), with a high mix of silicon technologies and manufacturing processes. The test process often requires very specialized test equipment with minimal automation which results in operators initiating and ending a test data log for each device under test (DUT).
In these mission-critical systems the premium on zero escapes coupled with the low part volume enables product and quality engineers to balance the yield/quality/cost triangle towards quality. Deeper data analysis of test results and the ability to promptly respond to customer returns enables these engineers to decrease test escapes as well as do a risk assessment for their customers.
Device providers shifting from supplying a consumer product to this industry sector need to add on business and engineering processes to meet government contractual requirements for archiving. This enables full traceability and the analysis of tens of years of data.
Engineers value the following YMS functionality found in yieldWerx products:
- Wafer/Bank/Scrapping/Down Grading Management
- Outlier detection
