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

    University essay from Linköpings universitet/Fordonssystem

    Author : Gabriel Fredriksson; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  6. 5. Design and construction of modular event detector system

    University essay from Institutionen för systemteknik

    Author : Jenny Ericsson; [2003]
    Keywords : Datorteknik; datorteknik; miljötest; Lab VIEW; avbrottsdetektion; byggsätt; modulär elektronik; Datorteknik;

    Abstract : This thesis describes the function and construction of a modular event detector system. Event detectors are used for solder joint reliability testing using electronic monitoring for short duration resistance changes during accelerated ageing and temperature cycling. Collected data is mainly used to study solder joints long-term properties. READ MORE
