- Certified 10y agoI have not knowingly seen this used in the wild but it looks intriguing. I've seen a lot of conformal coatings used to increase shock resistance but from my experience that is only half the battle. The thermal expansion and contraction can be the real slow silent killer. The caveat being that I was dealing with devices rated (and used) from -30°C to 85°C.
- bravo22 10y agoIt gets used quiet often, even Nest uses it [1]. Obviously proper heat management is important. 1. https://cdn.sparkfun.com/assets/8/5/c/7/4/52e157adce395f47598b4567.jpg https://cdn.sparkfun.com/assets/8/5/c/7/4/52e157adce395f4759...
