  1. 1. Post-processing for roughness reduction of additive manufactured polyamide 12 using a fully automated chemical vapor technique - The effect on micro and macrolevel

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ingrid Johansson; [2020]
    Keywords : Chemical post-processing; PostPro3D; selective laser sintering; surface roughness; polyamide 12; Kemisk efterbehandling; PostPro3D; selektiv lasersintring; ytojämnhet; polyamid 12;

    Abstract : Additive manufacturing has increased in popularity in recent years partly due to the possibilities of producing complex geometries in a rapid manner. Selective laser sintering (SLS) is a type of additive manufacturing technique that utilizes polymer powder and a layer-by-layer technique to build up the desired geometry. READ MORE

  3. 2. Indium Bump Fabrication using Electroplating for Flip Chip Bonding

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Saron Anteneh Sjödin; [2015]
    Keywords : Pixel Detector; Read Out Chip; UBM; Bump; Electroplating; Evaporation; Reflow;

    Abstract : Hybrid pixel detectors are widely used in many fields, including military, environment, industry and medical treatment. When integrating such a detector, a vertical connection technique called flip-chip bonding is almost the only way to realize the high-density interconnection between each pixel detector to the read-out chip.
