Wendy Luiten Philips Research, Eindhoven, the Netherlands INTRODUCTION Active LEDs in a consumer TV product are boosted and dimmed with the video picture content. Boosting and dimming of the LEDs is a powerful means to improve visual experience, either through application of active LEDs in an ambient light feature, or through dimming and boosting of the display LEDs in a … [Read more...]
Challenges in Measuring Theta jc for High Thermal Performance Packages
Jesse Galloway and Ted Okpe Amkor Technology One of the more challenging thermal resistance measurements to make for electronic packages is the junction-to-case resistance called Theta jc. The equation for Theta jc, equation (1), is straightforward. However, the difficulty lies in making an accurate case temperature, Tc, without affecting the junction temperature, Tj, and the … [Read more...]
Estimating the Thermal Interaction between Multiple Side-by-Side Chips on a Multi-Chip Package
Je-Young Chang and Ashish Gupta Intel Corporation INTRODUCTION Integration using multi-chip packaging (MCP) is an effective and popular technology option to increase transistor density in one component by integrating two or more dice or other discrete components on a common substrate. For accurate thermal analyses of MCPs, thermal interactions between active components need … [Read more...]

Researchers Pinpoint Heat Movement in Nanostructures
Researchers at Cornell University have developed a new method of precisely measuring the subtle movement of heat in nanostructures. Heat flows at the nanoscale differently than at larger scales, the researchers say, and understanding how certain surfaces affect the transport of heat at the phonon level could have implications in everything from thermoelectric materials to … [Read more...]
