How to Properly Measure Temperature within Electronic System and Analyze the Results
. by Dr. Kaveh Azar, Ph.D., President and CEO of Advanced Thermal Solutions,
There is a cost to bad data. While modern electronics are very reliable within a short (3-5 years) life cycle in the market, there is not enough to time to develop a significant model for failure analysis. Because of this, accelerated testing at different temperatures and temperature schemes become the most commonly used practice to identify expected life. In fact, temperature becomes a key parameter impacting the expected life of a device, PCB and system. Since temperature is the driver, to what level of accuracy can we determine its magnitude and what is the impact on reliability prediction?
Reliability models include temperature as a key part of the model and it is the magnitude of temperature change which plays a significant role in the value of reaction rate and the subsequent reliability prediction. So how accurately can we predict the temperature to understand that magnitude of change and help in the determination of a devices' reliability?
These two key questions and more will be addressed in this tutorial. Attendees of this tutorial will deepen their understanding of the importance of accurate temperature measurement in electronic systems in order to answer these two key questions They will learn about sensors, thermocouples, thermistor, calibration, their use and analysis of results. In addition attendees will learn about the semiconductor thermal test chips, IR, liquid crystal thermography and calibration.
