    Sammanfattning : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. LÄS MER

  4. 8. Cone Crusher Performance

    Författare :Magnus Evertsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mining; size-reduction; particle size; crushing; comminution; modelling; simulation; aggregates;

    Sammanfattning : Cone crushers are used by both the aggregate producing and the mining industry. Both industries are interested in increasing the product quality while at the same time lowering the production costs. Prediction of crusher performance has been focused on, since crushing is a vital process for both industries. LÄS MER

  5. 9. Selective Comminution Applied to Mineral Processing of Critical Metals

    Författare :Lorena Guldris Leon; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective comminution; compressive crushing; analytical method; minerals; critical metals; elements.;

    Sammanfattning : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. Due to the vital economic importance and limited supply, growing interest places these metals on the critical metals risk list. LÄS MER

  7. 10. X-ray microcomputed tomography (µCT) as a potential tool in particle-based geometallurgy

    Författare :Pratama Istiadi Guntoro; Yousef Ghorbani; Jan Rosenkranz; Veerle Cnudde; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray microcomputed tomography; Mineralogy; Texture; Liberation; Geometallurgy; Mineral Processing; Mineralteknik;

    Sammanfattning : In recent years, automated mineralogy has become an essential tool in geometallurgy. Automated mineralogical tools allows the acquisition of mineralogical, textural, and liberation information of ore samples. Such information is essential in the context of geometallurgy where it is needed for estimating the process response of the ores. LÄS MER
