Reliability

Which typical reliability test evaluates lifetime and failure rate by operating products at high temperature for a long time?

  1. ATemperature cycling test
  2. BHigh temperature operating life test (HTOL)
  3. CDrop test
Show answer and explanation

Answer: B. High temperature operating life test (HTOL)

The HTOL (High Temperature Operating Life) test operates products at high temperature under voltage for a long time and examines the occurrence of failures. Using temperature acceleration, it estimates lifetime and failure rate in actual use from a short test time.
