Failure Analysis Technicians are responsible for investigating and analyzing product failures to identify the root cause and prevent future occurrences. Their key responsibilities include:

1. Failure Analysis

Investigating and analyzing product failures using various techniques, such as microscopy, spectroscopy, and mechanical testing, to determine the root cause of the failure.

• Conducting physical examinations of failed components to identify potential sources of failure.
• Utilizing specialized equipment and techniques to perform chemical, metallurgical, and electrical analysis.

2. Root Cause Identification

Determining the underlying cause of product failures based on the analysis results. This may involve identifying design flaws, manufacturing defects, or environmental factors that contributed to the failure.

• Analyzing data and test results to identify patterns and draw conclusions.
• Developing and testing hypotheses to determine the root cause of the failure.

3. Failure Prevention

Recommending corrective actions to prevent future product failures. This may involve proposing design changes, improving manufacturing processes, or implementing new quality control measures.

• Collaborating with engineers and production teams to develop and implement corrective actions.
• Monitoring product performance after corrective actions have been implemented to ensure effectiveness.

4. Documentation and Reporting

Documenting the failure analysis process and results in detailed written reports. These reports include the description of the failure, the root cause analysis, and the recommended corrective actions.

• Communicating the findings of the failure analysis to stakeholders, including engineers, management, and customers
• Maintaining accurate records of all failure analysis activities.
