Thermal Stress Testing - Breaking Old Habits
When to assess quality and reliability test resources
Thermal chambers have found a place in the psyche of test, quality, and production engineers - and for good reason. They can be an ideal test environment when precisely matched to the test specifications. However, often times they are not.
This article, originally published in Quality Digest, discusses the difference between chambers and temperature forcing and how to optimize both to improve time, accuracy, and uniformity for thermal cycling, device characterization, and stress testing.
