1. 1. Solder Matrix Fiber Composite Thermal Interface Materials

   Författare :Josef Hansson; Chalmers University of Technology; []
   Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; thermal management; composite materials; solder; thermal interface material;

   Sammanfattning : Overheating has been a problem for microelectronics devices for decades, and the problem is exacerbated by the continued trend of miniaturization of features and the corresponding increase in power density. Thermal interface materials (TIMs) target one of the main bottlenecks in heat transfer: the interface between two materials, such as between a heat-generating microchip and a heatsink. LÄS MER

3. 2. Fabrication and Characterisation of Carbon Nanotube Array Thermal Interface Materials

   Författare :ANDREAS NYLANDER; Chalmers University of Technology; []
   Nyckelord :carbon nanotubes; reliability test; thermal management; thermal interface material; chemical functionalization;

   Sammanfattning : The performance of electronic devices has long been limited by thermal dissipation which will result in device failure if not handled properly. The next generation of integrated circuit (IC) devices will feature new packaging technologies like heterogeneous integration as well as 3D stacking which entails additional emphasis on the thermal management solutions employed.
