    Sammanfattning : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

  4. 8. Electrical Properties of Carbon Black Polymer Composites: Filler Particle Rearrangement

    Författare :Karl Michael Jäger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductivity; fractal; permittivity; carbon black; dielectric; electron tunnelling; polymer; image analysis; cluster; percolation;

    Sammanfattning : The practical application of semi-conducting carbon black polymer composites often involves temperature variations resulting in changes in their electrical properties. Study of cross-linked ethylene butylacrylate copolymer (EBA) filled with acetylene black has shown that these changes are due to carbon black network re-arrangement. LÄS MER
