Introduction During the last ten years, developments in LED semiconductors have led to an important change in LED applications from that of luminous indicator to that of illuminator. With LEDs now advancing into several lighting fields, LEDs have become one of the standard methods of producing light, joining more traditional sources such as incandescent, fluorescent and … [Read more...]
Packaging Challenges For High Heat Flux Devices
Introduction It comes as no surprise to anyone in our industry that device power levels are increasing to support customer expectations of ever greater functionality and performance. The greatest thermal challenges in computing occur in the packaging of processors. This results not only from the fact that processors typically have the largest overall power dissipation in a … [Read more...]
Thermal Conductivity of Solders
Soldering has been a primary method of establishing mechanical and electrical connections in electronics for many years and will likely be used in this fashion in the future. While there are several physical properties and characteristics of solders that are of interest to the electronics community at large, one of the most significant physical properties to a thermal engineer … [Read more...]
An Overview of Liquid Coolants for Electronics Cooling
Introduction The cooling of electronic parts has become a major challenge in recent times due to the advancements in the design of faster and smaller components. As a result, different cooling technologies have been developed to efficiently remove the heat from these components [1, 2]. The use of a liquid coolant has become attractive due to the higher heat transfer coefficient … [Read more...]
Direct Die Attach Using a Room Temperature Soldering Process
As the power and power density of IC components continue to rise [1], the need to effectively dissipate the heat to ensure long-term reliability has increased [2]. The largest contributor to the total thermal resistance along the heat conduction path comes from the thermal interface material (TIM) used between the surfaces of the silicon die and the heat spreader or heat sink. … [Read more...]
