Support and audit OSATs to ensure compliance with test procedures, quality standards, and documentation.
Participate in test hardware reviews (load boards, probe cards) and interface with test engineering and hardware design teams.
Test Process Improvement
Drive root cause analysis and resolution of test escapes, yield losses, and test time inefficiencies.
Analyze test data to identify trends, anomalies, and areas for improvement.
Work with OSATs to implement process changes or test optimization strategies to enhance throughput, yield, and test coverage.
Support Golden Device and correlation activities between sites,
testers, and test platforms.
NPI and Change Management
Support New Product Introduction (NPI) from test development handoff to production ramp at OSATs.
Coordinate with R&D and central test engineering to validate and release test programs.
Manage test engineering change orders (ECOs), including program revisions, binning changes, and test flow updates.
Ensure seamless test program and hardware transitions across test platforms or OSAT sites.
Documentation & Reporting
Maintain up-to-date documentation of test flows, procedures, change logs, and qualification records.
Generate regular reports on test KPIs (yield, OEE, retest rate, escapes, etc.) for both internal and customer review.
Track and report OSAT performance metrics, and lead business reviews with key stakeholders.
