  1. 1. Warpage Prediction of Electronic Underfill Components During Curing

    University essay from Umeå universitet/Institutionen för fysik

    Author : David Lindblom; [2021]
    Keywords : Warpage; viscoelastic;

    Abstract : To ensure the shelf life of a semiconductor, the integrated circuits are usually embedded in an epoxy molding compound (EMC) to shield it from stress and corrosion. The EMC is a viscoelastic material and is categorized as a thermoset. Working with viscoelastic material appose a challenge due to the cure-induced warpage. READ MORE

  3. 2. Crack growth based FEM with embedded discontinuities

    University essay from KTH/Hållfasthetslära

    Author : David Lindblom; [2021]
    Keywords : PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

    Abstract : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

  4. 3. Automatic System Tests on Airborne Radar Systems

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sebastian Lindblom; David Johansson; [2018]
    Keywords : ;

    Abstract : The aim of this master thesis was to create automated system tests on airborne radar systems. Automated tests can reduce time spent on repetitive and monotone work and instead create time for exploratory testing and customer criteria testing. Nightly builds and well designed tests can improve robustness and create a more stable system for the user. READ MORE

  5. 4. A PERSPECTIVE ON PRIORITIZATION IN PROJECT PORTFOLIO ENVIRONMENT

    University essay from KTH/Industriella informations- och styrsystem; KTH/Skolan för elektro- och systemteknik (EES)

    Author : Henrik Eberhardt; David Lindblom; [2011]
    Keywords : Project portfolio; project prioritization;

    Abstract : The overbridging aspect of this interpretative master thesis is the implementation of a project prioritizing strategy. The concept is subdivided into three processes and entities, which could be seen as tools; project management office(PMO), project evaluation and project selection, which in turn are discussed separately.
