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...]
Utilizing Laser Flash in Combination with Finite Element Modeling to Analyze Thermal Conductivity of Interfaces and Layers within Complex Structures
Abstract The utility of the laser flash thermal conductivity measurement can be greatly expanded to more complex structures by modeling laser flash results using Finite Element Models. This approach is illustrated using a test fixture with 4 heat sinks, where heat spreading is a significant factor. If traditional 1D thermal diffusion models for laser flash are used, thermal … [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...]
Statistics Corner: Weibull Distribution
A little over a pandemic ago, the first article in this series on statistical analysis mentioned that a fundamental aspect of statistics is that one assumes a mathematical model that describes the distribution of a data set and then uses that model to estimate the probability that a given value or set of values will occur [1]. This allows us, for example, to estimate whether … [Read more...]
