  1. 1. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gabriel Fredriksson; [2022]
    Nyckelord :machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Sammanfattning : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. LÄS MER

    Sammanfattning : At present there are different reliability standards that are being used for carrying out reliability prediction. They take into consideration different factors, environments and data sources to give reliability data for a wide range of electronic components. LÄS MER

  4. 3. The effect of rework on brittle fractures in lead free solder joints : The growth of intermetallic compounds during rework and its effects

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet

    Författare :Elin Dornerus; [2009]
    Nyckelord :Intermetalliska skikt; sprödbrott; lödfogar; blyfritt; Intermetallic layers; Intermetallic growth; brittle fractures; solder joints; lead free; RoHs;

    Sammanfattning : Saab Microwave Systems, SMW is a supplier of radar systems. The circuit boards that are operating in their radars have components which solder joints contains lead. However, the EU directive RoHs and WEEE are causing SMW to prepare for a transition to lead free solder joints. LÄS MER
