Most engineers involved with temperature measurement know there are several methods for measuring temperatures of fluids and solids. The oldest and most common method for measuring the temperature of a fluid such as air is the standard mercury-in-glass thermometer. However, this is not acceptable for measuring surface temperatures of solid objects. For surface temperature … [Read more...]
Simulation of Solder Fatigue Effects on Typical BGA Package due to Material and Temperature Variations – Part 2
Abstract The past two decades have seen many approaches to solder fatigue and solder joint life published. This subject has proved difficult as various failure mechanisms are proposed and examined. While these theoretical bases are discussed, it often leaves the end developer in a difficult situation as to how to apply an accurate simulation approach to fatigue failure for a … [Read more...]
Radiation Basics: Making Sense of Emissivity & Absorptivity
Introduction This is the second installment in a series of articles that aims to explore a range of practical topics on radiation that are relevant to those of us focused on electronics cooling and thermal design. The last article [3] provided guidance regarding when radiation matters, with examples being natural convection environments, space applications, solar collectors, … [Read more...]
Report About the THERMINIC 2024 Workshop
By Andras Poppe and Marta Rencz The 30th THERMINIC (Thermal Investigations of ICs and Systems) workshop was held on 25-27 September 2024 in Toulouse, France at the Mercure Toulouse Centre Compans. Jean-Pierre Fradin (Icam, France) and Patrick Tounsi (INSA Toulouse & LAAS – CNRS) as local organizers and co-program chairs of the 2024 THERMINIC did a great job: Over 110 … [Read more...]
