Comprehensive PCBA Failure Analysis in San Diego and Southern California
PCBA failure analysis is more than a service, it’s a commitment to engineering excellence. When you’ve identified a failing PCBA in your system, KEEN TRACE is here to uncover the underlying failure mechanism and root cause. We specialize in the diagnosis and analysis of faulty PCBAs, including their electrical components, integrated circuits, and modules. Our expert team delivers precise, data-driven insights to identify failure mechanisms and root causes with clarity and confidence.
Our Methodology: A Step-by-Step Approach
Our thorough analysis consists of a detailed, multi-step process designed to ensure comprehensive insights into your PCBAs:
Inspection and Verification
- Advanced Optical and X-ray Inspection
A meticulous screen of the failing unit is performed to detect any visible anomalies or defects. - Failure Verification
The reported failure mode is then confirmed through rigorous testing. - Review of Technical Documentation
We then analyze available datasheets, schematics, and layouts to understand the design context of failure.
Electrical Fault Isolation and Localization
- DC Analysis
We conduct voltage and current measurements at critical nodes and test points, to identify any abnormal DC characteristics. - Signal Probing
Our team then probes suspect signals utilizing various bench test equipment to identify irregularities and anomalous signatures. - IR Thermal Analysis
We identify suspect failure sites or components by observing thermal characteristics while exercising the failure mode.
Component and Physical Failure Analysis
- Isolation of suspect components
Then, our team isolates and extracts suspect components for further in-depth examination. - IV Curve Tracing of Suspect Components
We then study pin to pin electrical characteristics of the suspect devices to gain deeper insights. - Physical Failure Analysis
To gain deeper understanding of the physical failure mechanisms at play, we perform component decapsultaion and inspection or physical cross-section of the suspect PCBA location.
Final Report
- Comprehensive Documentation
After completion of our in depth step by step process, we provide you with an exhaustive report detailing our findings. This comprehensive report includes the identified root causes and actionable recommendations for improvement.
