Hi Poul: I used a Barnes IR device that had a very small spot size (worked like a microscope) to try and measure the temperature of components on a board, but the emissivity varied all over the place so could not get temperatures unless everything was painted black. Especially hard to measure were devices in metal packages that were essentially mirrors.
