The rapid rise of AI accelerators and high-performance computing has pushed rack power densities to unprecedented levels. While direct-to-chip liquid cooling successfully manages heat at the processor, the power delivery path itself has emerged as the next critical thermal bottleneck. Recently, Electronics Cooling sat down with Vic Geevarghese, Director of Operations of … [Read more...]
MEMS-Based Solid-State Airflow for Compact Thermal Management
As consumer electronics continue their rapid evolution, each new generation is defined by a familiar yet intensifying mandate: deliver more performance in less space. Today’s devices — whether smartphones, wearables, or portable computing platforms — are expected to be thinner, lighter, and more power-efficient, while simultaneously supporting increasingly demanding workloads … [Read more...]
Thermal Facts and Fairy Tales: Misusing Theta JA to Calculate Junction Temperature
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...]
Summary of SEMI-THERM 42 Conference
