Thermocouples are widely used for temperature measurements. They are particularly useful in lab testing, due to their relatively low cost and the ability to easily fabricate thermocouples of specific lengths for a given test. This Tech Brief discusses issues related to the size of a thermocouple that may be considered when using them. A thermocouple consists of two wires made … [Read more...]
Summary of the IEEE ITherm 2023 Conference
The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the JW Marriott Grande Lakes, Orlando, FL, May 30 – June 2, 2023. This was the 22nd ITherm, which was first held in 1988. The conference was historically held every other year until 2016 when it switched to an annual schedule. ITherm 2023 was sponsored by the … [Read more...]
Calculating Thermal Design Power for Mobile Consumer Electronics – Part 1
Thermal Design Power (TDP) is a term commonly used in the thermal management of consumer electronics. While the usage of this terminology may vary across the industry, it commonly refers to the amount of power that a device may dissipate indefinitely, in a given thermal environment, without exceeding the temperature limits of the device. The TDP for a consumer electronics … [Read more...]
Calculating Interface Resistance
Introduction The exposed surface area of many of today’s high-powered electronic packages is no longer sufficient for the removal of the heat generated during normal operation. Heat sinks are a commonly-used, low cost means of increasing the effective surface area for dissipating heat by means of convective air cooling. While the use of a heat sink lowers the fluid-side … [Read more...]
Thermal Modeling of a Silicon Germanium (SiGe) Radio Frequency Integrated Circuit (RFIC) for Wireless Communications
The creation, transport and storage of digital information are growing at rates of 40% to 50% annually, with video, mobile broadband, and machine-to-machine communication being the main drivers. The implementation of 5G wireless networks is enabling this growth and heralding a new era of revolutionary applications and functionality due to bandwidth increases and communication … [Read more...]
