A misconception that experienced thermal engineers have likely encountered is related to the improper use of Theta JA (θJA) of an electronic component. Many electrical and reliability engineers are taught that the junction temperature of an electronic component in any electronics packaging configuration or application may be calculated by the equation below. Here, TJ represents … [Read more...]

Alternative Battery Module Configuration for Fast Thermal Runaway Detection with a Reduced Number of Temperature Sensors
Abstract With increasingly strict regulations on lithium-ion battery (LIB) thermal runaway (TR) and safety, rapid detection has become essential to ensure passengers can evacuate safely in electric vehicles (EVs). Early TR detection requires temperature sensors to monitor battery behavior. Incorporating many sensors increases both cost and system complexity, so commercial … [Read more...]
Spacecraft Thermal Control in Extreme Environments: Surviving Lunar Night and Martian Dust
Abstract Extreme conditions in interplanetary environments, like lunar night at -173°C and Martian dust storms, require new thermal control systems that go beyond traditional electronics cooling approaches. Martian dust consists primarily of iron-oxide and silicate particles with diameters ranging from 1 to 3 μm. These particles are electrostatically adhesive, capable of … [Read more...]
Rethinking Thermal Design Priorities in Electronics Packaging
Steady state operating temperature is a critical design parameter for ensuring the reliable operation of modern electronics systems. However, in practice it is but one of many factors that impact overall system health and performance. Modern challenges, like the large transient power draw associated with artificial intelligence (AI) workloads create the potential for more … [Read more...]
