Thermal Cycling

Environmental Stress Requirement Sub-Categories

Testing For:

  • Components, equipment or other articles to withstand rapid changes of ambient temperature
  • Connectors for electronic equipment
  • Semiconductor devices
  • Fiber optics
  • It applies when the product specification calls for a reliability growth program of equipment (electronic, electromechanical and mechanical hardware as well as software) or when it is known that the design is unlikely to meet the requirements without improvement
  • Solder joints, glued interfaces and other parts that are stressed by differences in CTE
  • Components and solder interconnects
  • Semiconductor devices
  • Tin and tin alloy surfaces
  • Design for Reliability Processes - Early in the design processes, Highly Accelerated Life Testing (HALT) is utilized to expose early prototypes and existing components to the full range of expected operating conditions, within a controlled environment

Failure Type :

F(r) = Failures accelerated by rapid thermal change rates (some solder issues, timing issues and mechanical issues)

Typical Failures Detected:

  • Different parts of unit can be at different temperatures, maximizing parametric drift issues.
  • Transient software issues detected due to tight timing.
  • Mechanical fatigue of rapid thermal causes faulty solder joints or components to crack.
  • Mechanical mismatch that causes excessive stress and failures.
  • Hardware values that shift unevenly out of compensation range of SW/FW.
