Q: What's the best technique for temperature management of sensitive components in extreme environments?

摘要

Wilson Lee, Director of Product Marketing, Newark elements Engineers may underestimate the importance of thermal management, but it is critical to utilize techniques at the production level that reflect the real environment in which their build or components may exist. In my experience, I have found engineers make two common mistakes during temperature management. The first mistake is engineers rely strictly on the product specification sheet, which tests components in a lab setup, without a true frame of reference for how the part operates or its functionality within a larger design environment. There are nuances to the design process that the spec sheet won't consider: forced air cooling for an out-of-bound temperature range, power source reliability and quality/cleanliness of the operating environment, to name a few. Instances where a design engineer is designing components for use in another part of the world can pose challenges too, as they are sometimes not able to sufficiently simulate the in-use environment. Disregarding the real operating environment in which components are used can result in thermal failure.
