Early Life Failure Rate (ELFR) Test

Equipment: Thermal Chamber

Working Principle

  • Look at the failure rate in the first 3-6 month
  • Monitor the failure rate during usage
  • Understand the increasing of failure rate

Technical Information

  • Monitor the duration of “Infant Mortality” (3-6 months)
  • Measure and calculate early life failure rate
  • Observe performance in use
  • Collect failure rate and mode in wear out stage
