Thanks guys for your comments.
I tend to agree that we don't have a reflection problem and there is no heat source to provide a problematic reflection. There is conformal coating on the chip however which is more reflective than the chip on it's own, I think I'll scrape some off as a test to...
Hi,
We have been measuring the surface temperature of a problem chip using a thermocouple and an IR gun but are getting temperatures that are approximately 30 deg C different, the IR gun providing the higher reading. Other companies have been measuring this chip with a thermocouple and the...
