Electronic assembly reliability

• INTRODUCTION
  • Reliability definitions
  • Failure, failure mode and failure mechanism
  • Abrupt (catalectic) and wear failure
  • Example of failure mechanisms
  • Resistance/stress theory
• SOME MATHEMATICAL NOTIONS
  • Failure rate function l(t)
  • Evolution of failure rate over time (bathtub curve)
  • MTBF, MTTF
  • Use of statistical laws and their limitations :
    • Exponential
    • Weibull
  • Sampling :
    • Ki²
    • Binomial
• OUR APPROACH: “RELIABILITY THROUGH TECHNOLOGY
  • Theoretical methods (MIL-HDBK-217, IEC 62380, FIDES)
  • Use of REX
  • Per test
• OUR APPROACH: “RELIABILITY THROUGH TECHNOLOGY
  • Definition of product life profile
  • Risk analysis (technologies versus life profile)
    • Components and technologies : AEC-Q-XXX, PPAP, aeronautics, space…
    • Design
    • Industrialization
  • Robustness testing
    • HALT
    • Development and implementation of a test plan
  • Durability testing
    • Acceleration laws (Arrhenius, Coffin Manson and Norris Landzberg, HallbergPeck …)
    • Building a test plan and sequencing tests
  • Manufacturing process qualification
    • Process control
    • Supplier audit
• BURN-IN
  • Definition of burn-in
  • HASS, HASA, ESS
  • POS and SOS
  • Burn-in effectiveness
• PRACTICAL EXERCISES ON A CASE STUDY
• Throughout the training course, trainees are offered a number of exercises:
  • Mathematical exercises (exponential, Weibull…)
  • Life profile definition
  • Technological risk analysis and industrialization
  • Definition of a robustness plan
  • Definition of a durability test plan (calculation of accelerated tests)
• CLASSICAL RELIABILITY ASSESSMENT METHODS
  • Theoretical calculations (MIL-HDBK-217, IEC 62380, FIDES)
  • Test methods (D0 160, EN 50155, ESA…)
  • Field feedback (REX)
