Resumen o descripción
This paper develops a device capable of confirming the minimum coverage area on a thermistor by a thermal paste dispensed and cured in the manufacturing process of Exhaust Gas Recirculation (EGR) temperature sensors to provide the required fixation in the presence of mechanical shock conditions. Such a device leverages the thermistor’s self-heating effect and the thermal conductivity of the paste to read the voltage drop from the sensor, which translates into paste coverage area. The methodology follows a synthesized procedure to develop equipment and processes, considering an early phase for concept confirmation to demonstrate the feasibility of the device development. In a later phase, the optimal parameters are calculated and set to the device for delivering the corresponding classification of the sensors during the test. Once launched in production, the device demonstrates high effectiveness in screening out the sensors with rejectable paste coverage area on the thermistor.
