Failure analysis (RCA) of electronic circuit boards

• DEFINITIONS
  • Defect, failure mode, degradation, failure mechanism, failure cause, root cause
• INTRODUCTION TO CAUSE-FINDING STEPS
  • Situation analysis: description of the fault and the context in which it occurred
  • Fault confirmation/characterization
  • Locating the fault at board and component level
  • Observation/expertise of the fault
  • Search for and weighting of failure mechanism
  • Search and weighting of failure causes
• FAULT DESCRIPTION AND CONTEXT OF OCCURRENCE
  • Product and fault description
  • The product: its design, manufacturing process, history, etc.
  • The fault: facts (data), conditions of occurrence, feedback, etc.
  • Methods: QQOQC, 5W, IS-IS NOT, Graph, …
  • Examples
• METHODS FOR LOCATING/CHARACTERIZING FAULTS ON A MAP
  • Failure modes and their special cases (intermittence, instability, combustion, etc.)
  • Location tools (objectives, limits and risks of altering the fault)
  • Introduction to families of degradation mechanisms
  • Fault characterization methods
  • Consistency analysis of results
• INTRODUCTION TO FAILURE MECHANISMS
• FORMALIZING ASSUMPTIONS AND WEIGHTING CRITERIA (OBJECTIVES, METHODS, MEANS, LIMITS)
  • Application example
• ELECTRONIC BOARD FAILURE CAUSES AND WEIGHTING
  • Reminder of definition: what is / is not a cause
  • Review of electronic board failure cause families
  • Hypothesis review methods: Brainstorming, Fault tree, Cause-effect diagram, Mind mapping, ….
  • Weighting tools and criteria (objectives, methods, means, limits) :
    • Experimental design
    • Laboratory expertise
    • Robustness testing
    • Manufacturing process audit
    • Field measurements
    • Expert opinion, etc.
  • Example
• CAUSE AND ROOT CAUSE OF ELECTRONIC BOARD FAILURE
