New SEM Lab book

Failure Analysis of Electronic Components & Assemblies

Ed Hare, Ph.D. · SEM Lab, Inc.

Follow SEM Lab investigations from a reported symptom through electrical testing, microscopy, and specimen preparation. The cases show how measurements and physical evidence locate a failure, distinguish possible mechanisms, and establish what can be reported with confidence.

Inside the book

From investigation planning to reporting

  1. Foundations Plan the investigation and distinguish failure modes, mechanisms, and causes.
  2. Analytical methods Optical inspection, scanning electron microscopy, EDS, and specimen preparation.
  3. Materials and metallurgy Solder joints, surface finishes, reaction interfaces, and assembly damage.
  4. Component-level failures Packages, board and substrate interconnections, leakage, and LED failures.
  5. Assembly-level failures Solder-joint fracture, printed wiring board construction, and mechanical loading.
  6. Electrical and environmental failures Electrical overstress, ESD, corrosion, and conductive growth.
  7. Worked case studies Investigation sequences, interconnection damage, and fretting at an internal camera connector.
  8. Interpretation and reporting Set the limits of a finding and connect it to a corrective action or further measurement.
