Core Responsibilities

Primary Functions

Execute comprehensive, hands-on failure analysis on a wide range of electronic components, PCBs, and system-level products to meticulously identify root cause failure mechanisms.
Operate, calibrate, and maintain advanced analytical laboratory equipment, including Scanning Electron Microscopes (SEM), Energy Dispersive X-ray Spectroscopy (EDS/EDX), and Focused Ion Beam (FIB) systems.
Perform non-destructive analysis techniques such as 2D/3D X-ray imaging, acoustic microscopy (C-SAM), and thermal imaging to inspect internal structures for defects without damaging the sample.
Conduct destructive physical analysis, including mechanical or chemical decapsulation, cross-sectioning, polishing, and dye & pry techniques to expose and examine internal device structures.
Utilize a variety of electrical fault isolation tools, such as curve tracers, oscilloscopes, multimeters, and time-domain reflectometry (TDR) to characterize electrical failures.
Prepare detailed, high-quality failure analysis reports that clearly document procedures, present evidence (images, data), and articulate the root cause and failure mechanism for an engineering audience.
Collaborate directly with design, reliability, product, and process engineers to discuss failure trends and provide data-driven feedback for corrective actions and design improvements.
Meticulously document all analysis steps, observations, and results within a database or tracking system to ensure data integrity and traceability.
Develop and refine failure analysis techniques and standard operating procedures (SOPs) to improve the efficiency, accuracy, and capabilities of the FA lab.
Manage the workflow of incoming failure analysis requests, prioritizing tasks based on urgency and impact on production or product development cycles.
Perform sample preparation involving precise handling, mounting, and modification of delicate components to ready them for advanced microscopic and electrical analysis.
Analyze failures originating from various sources, including manufacturing yield loss, customer field returns (RMAs), and reliability qualification testing.
Isolate failure locations using advanced techniques like thermal emission microscopy (EMMI), laser voltage probing (LVP), and optical beam induced resistance change (OBIRCH).
Maintain a safe and organized laboratory environment by adhering to all safety protocols, including chemical handling (MSDS) and equipment safety procedures.
Interpret complex circuit schematics and board layout files to understand device functionality and guide the fault isolation process effectively.
Conduct thorough visual and microscopic inspections at various magnification levels to identify subtle physical defects like cracks, corrosion, contamination, or electromigration.
Replicate failure conditions reported from the field or production floor in a controlled lab setting to verify the failure mode.
Provide clear and concise summary presentations of critical failure analysis findings to cross-functional teams and management.
Assist in the evaluation and acquisition of new analytical tools and technologies to keep the lab's capabilities at the cutting edge.
Train junior technicians and engineers on standard failure analysis procedures and the operation of specific laboratory equipment.

Secondary Functions
