The PFA & EFA Technician will provide comprehensive Electrical Failure Analysis (EFA) and Physical Failure Analysis (PFA) support for products across NPI, qualifications and high-volume manufacturing (HVM).  

A key part of this role is the disposition of maverick material triggered by the Statistical Bin Limit (SBL) system—using data-driven evaluation, structured troubleshooting, and effective collaboration with cross-functional partners. You will collaborate closely with key stakeholders to identify failure signatures, determine root cause and failure mechanisms, recommend lot disposition, and partake on continuous improvement to reduce and improve SBL fail rates. 

This position requires keen technical curiosity, disciplined execution, clear communication, and strict adherence to lab safety and quality systems in a fast-paced production environment. 

Key Responsibilities 

1) Maverick Lot Disposition via SBL System & Deviation Management 

Extract, interpret, and analyze test data to support SBL-triggered investigations. 

Execute and follow up on FA actions (EFA and/or PFA) to determine disposition paths. 

Recommend and communicate lot dispositions clearly and timely to stakeholders for quality control. 

Maintain strong working knowledge of test processes, equipment, systems, and product behavior to enable accurate decision-making. 

Document deviations and observations and provide feedback through the appropriate quality management system, ensuring traceability and compliance. 

2) Electrical Failure Analysis (EFA) 

Develop and maintain strong EFA skills across product technologies to identify root cause and understand failure mechanisms. 

Utilize advanced FA tools such as an IV curve tracer, micro-prober, and bench tester to perform EFA. 

Support site EFA activities including failure confirmation, characterization, and electrical failure data correlation studies. 

Provide EFA support and PFA recommendations for assembly failure cases and other escalations. 

3) Physical Failure Analysis (PFA) 

Conduct physical failure analysis and correlate electrical failure modes to physical defects when needed. 

Perform package and sample preparation activities such as:  

Package de-processing. 

Cross-sectioning support (manual and/or tool-assisted) 

IMC measurement (where applicable) 

Utilize layout and failure localization information to correlate suspected defect locations. 

Operate FA lab tools such as Ion Miller, FIB, EDX, SEM, 2D/3D X-ray, Thermal EMMI, and other laboratory equipment. 

Capture, save, and organize images and data; write structured, detailed FA documentation and reports with clear conclusions and supporting evidence. 

Coordinate with vendors for tool maintenance, upgrades, and service support; support general tool upkeep and lab readiness. 

4) Continuous Improvement & Productivity 

Propose and implement engineering and technical improvement ideas to reduce SBL triggers and optimize SBL disposition efficiency for EFA/PFA workflows. 

Assist engineers with initiatives to improve FA efficiency, effectiveness, and consistency (methods, tooling, templates, checklists, and standard work). 

Support labor productivity projects that improve throughput, reduce rework, and enhance reporting quality. 

Contribute to technical projects and, where applicable, support technical paper creation and knowledge sharing. 

Qualifications 

Nitec / Higher Nitec / Diploma in Electrical & Electronics Engineering, Computer Engineering, or a related discipline. 

Experience in test failure analysis, a lab environment, or manufacturing troubleshooting is a strong advantage. 

Enthusiastic working with data, diagnostic tools, and structured problem-solving methods. Able to work effectively in cross-functional teams and communicate clearly in a production environment. 

Required to work 12-hour rotating shifts. 

Preferred Skills 

Proficiency in FA tools and techniques (FIB, SEM, CSAM, Emmi, Oscilloscope, I-V Curve Tracer, ATE).
