In this application note from Analog Devices, you can get a quick refresher on the theories for conduction, convection and radiation heat transferring, as well as a briefing on how conduction is the most prevalent heat transfer method in PCBs. With this foundational knowledge presented, this application note further explores the correct PCB layouts for measuring PCB temperature and ambient temperature. Package considerations are also presented when considering package thermal resistance, power dissipated in the device, soldering temperatures, and response to thermal shock, including examples for measuring thermal shock in the ADT7301, AD590, AD592 and TMP17 sensors.
