USHANANTHINI CHINNAPPAN

• Lead DC/AC bench characterization of analog and logic devices in alignment with validation and verification (V&V) plans; ensured correlation between bench, simulation, and ATE data.
• Developed and implemented innovative lab test methods and hardware setups, including semi-automated AC/DC measurement systems to improve validation efficiency and accuracy.
• Operated advanced test equipment: Semiconductor Device Analyzer, Keysight EasyEXPERT, B2201 Switching Matrix, Oscilloscope, Signal Generator, Spectrum Analyzer, LCR Meter, Audio Precision, Network Analyzer, and other tools.
• Conducted comprehensive statistical data analysis (CPK, SPC, Six Sigma) to assess process control and validate product performance.
• Played a key role in NPI projects, coordinating validation activities, ensuring hardware availability (probe cards, testers), and driving closure on yield and reliability issues.
• Defined and executed quality and reliability testing (HTOL, HAST, ESD, Latch-up) per JEDEC and internal standards; worked closely with global teams for test site coordination.
• Reviewed test hardware and PCB design files, including schematics and Gerber files, to ensure validation readiness and signal integrity.
• Collaborated with designers, application engineers, test engineers, and product managers to interpret requirements, define validation strategies, and resolve technical issues.
• Investigated discrepancies in validation results; implemented root cause analyses and corrective actions for continuous improvement.
• Supported customer complaints and technical requests, providing test data, validation reports, and proposed solutions.
• Managed validation schedules by breaking down projects into milestones, assigning responsibilities, and tracking progress across teams.
• Compiled and presented validation gate reports to internal stakeholders and customers; ensured timely delivery of customer engineering samples.
• Conducted training sessions on lab tools, processes, and best practices; developed internal training documentation and supported mentoring of junior engineers.

Key Achievements:

• Supported NPI project as product lead for 3 months, successfully aligning internal stakeholders and external test sites for timely validation completion.
• Drove bench characterization process improvements that reduced test cycle time and improved correlation across test platforms.
• Streamlined coordination across design, test, and validation teams, contributing to early defect detection and faster project ramp-up.

• Collaborated with Product Engineers to address low yield and first-pass yield issues caused by test program instability and device-related failures.
• Ensured manufacturing test systems were fully operational and production-ready at all times.
• Responded promptly to test system issues, providing timely updates to relevant stakeholders.
• Drove continuous improvements in test system processes to enhance efficiency and reliability.
• Managed lot disposition and NCL (non-conforming lot) processes to ensure customer quality expectations were met.
• Contributed to test solution development, including writing basic segments of test programs.
• Investigated Electrical Customer Complaints (ECC), implemented corrective actions, and worked to prevent recurrence.
• Lead local qualifications for new test programs, products, and load board hardware.
