    Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

  3. 17. Automatisering av det interna flödet på ett tillverkande företag : En studie om den interna hanteringen av kretskortställningar och hur det kan effektiviseras i flödet

    Kandidat-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Ahmed Kadhim Abed; Erik Rappestad; [2023]
    Nyckelord :Transport flow; Circuit board racks; Automation; AMR systems; Waste; Bottlenecks.; Transportflöde; Kretskortställningar; Automatisering; AMR-system; Slöseri; Flaskhalsar;

    Sammanfattning : Purpose: The purpose of the study was to identify the current transport flow for circuit board racks and to investigate the potential implementation of an automated solution for the transportation of circuit board racks in order to increase efficiency in the flow. The research questions answered during this study were: What does the transport flow for circuit board racks look like today?  What could an automated transport flow for circuit board racks look like?  Is an automated transport flow for circuit board racks a sufficient solution to improve efficiency in the flow? Theoretical framework: The study applied several different theories, with waste being a central part. LÄS MER
