Temperature Cycling
Temperature Cycling is a testing method used in the automotive industry to make sure electronic parts can handle extreme temperature changes, similar to what a car experiences from winter to summer or from being parked in the sun to driving in cold weather. It's like putting car parts through a weather endurance test, where components are repeatedly heated and cooled to make sure they won't fail when used in real vehicles. This type of testing is essential for ensuring the reliability and durability of automotive electronics. You might also see this referred to as "thermal cycling," "thermal shock testing," or "environmental stress screening."

Example Interview Questions
Senior Level Questions
Q: How would you design a temperature cycling test program for a new automotive electronic component?
Expected Answer: A strong answer should cover planning test parameters based on vehicle usage conditions, determining appropriate temperature ranges and cycle times, considering industry standards, and explaining how to analyze and document results for regulatory compliance.
Q: How do you handle test failures during temperature cycling?
Expected Answer: Should discuss root cause analysis processes, demonstrate knowledge of common failure modes, explain documentation procedures, and describe how to implement corrective actions in the testing program.
Mid Level Questions
Q: What are the key parameters you monitor during temperature cycling tests?
Expected Answer: Should mention temperature ranges, ramp rates, dwell times, and explain how these factors affect electronic components. Should also discuss basic data collection and analysis methods.
Q: Explain the difference between temperature cycling and thermal shock testing.
Expected Answer: Should explain that temperature cycling involves gradual temperature changes while thermal shock involves sudden changes, and describe when each type of test is appropriate.
Junior Level Questions
Q: What safety measures do you take when conducting temperature cycling tests?
Expected Answer: Should be able to discuss basic safety protocols, proper handling of test equipment, and understanding of warning signs that indicate potential problems during testing.
Q: How do you document temperature cycling test results?
Expected Answer: Should demonstrate knowledge of basic test report writing, data recording, and understanding of why proper documentation is important for quality control.
