  2. 1. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

    Author : Christian Johansson; Hjalmar Hesselbom; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

    Abstract : 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. 2. Flip chip for high frequency applications : materials aspects

    Author : Katarina Boustedt; Dag Stranneby; Rao Tummala; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flip chip; underfill; bumping; microwave; gallium arsenide; high frequency; thermocompression; soldering; stud bumps; coplanar waveguide; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Elektronik; Electronics;

    Abstract : Flip chip has since decades been the primary choice for chip interconnect for high performance circuits. Over the last few years, interest from the microwave arena has increased, and at this point in time microwave flip chip is a possible option for volume production. READ MORE

  5. 3. High Frequency Tyre Vibrations

    Author : Patrik Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local deformation; adhesion; tyre model; air pumping; parameter study; tyre road noise; tyre road prediction models; tyre noise;

    Abstract : High frequency (above 1 kHz) noise generation from the tyre/road interaction is still not fully understood and accurately modelled.Two noise generation mechanisms previously suggested in the literature are reviewed: air pumping and noise generation cased by adhesive effects between the tyre tread and road surface.
