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
