Sixty to sixty-five percent of the heat generated on a printed-circuit board (PCB) is transferred to the temperature sensor die via its pins. The GND pin is connected to the substrate, and therefore has the least thermal resistance between temperature sensor and heat source. This paper provides tips for efficient PCB temperature measurement.
