The engineers at engineering consultancy R&D CFD are accustomed to applying CFD simulation to the challenges of Internal Combustion Engine (ICE) design. A recent project called on them to apply their analysis techniques to a different type of “ICE”--ICE cream. Their approach, however, was the same—using Simcenter STAR-CCM+ Multiphysics CFD software allowed the engineers to simulate 2000 variegator design variants in 17 days, and then optimize the design of the feeding chamber to guarantee that the final product would have the desired home-made, variegated appearance each time.

Thermal characterization is crucial for comprehending the behavior of complex electronics. It involves analyzing and measuring heat generation, dissipation, and management. This article provides a basic overview of thermal characterization, including structure and function of electronic components, and various techniques and tools used in the field. Get a better understanding of thermal characterization and its significance in ensuring the reliability and safety of electronic components.

The evolution of power, size, and temperature in electronics design has led to new challenges in system reliability and lifetime. In the past, overheating of critical components was the major cause of system breakdown, but today, other issues also arise. Cooling is a 3D effect, and accurate thermal characterization is necessary for optimal design. The development of thermal transient measurements has culminated in the Cauer-ladder network model and the Simcenter T3STER™ thermal transient analysis software system. Using structure functions, engineers can now identify the physical characteristics of layers and evaluate the thermal performance at the system level, from LED packages to laptops and laser printers.

The severity of the drop testing can be affected by a variety of factors, including the height of the fall, the surface on which the object lands, and the shape and composition of the object.

Shape and composition are two additional factors that affect severity. Objects with sharp edges or points are more likely to suffer damage than those that are smooth and round. Additionally, objects made of sturdy materials are less likely to break than those made of weaker materials.
