    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  3. 2. Optimization of the sorting process in PVC-floor recycling : Scenarios to optimize economic and environmental aspects of the upscaling sorting process

    University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Author : Emelie Jonsson; Birkir Pálsson; [2021]
    Keywords : Circular economy; Sorting process; PVC; Automation; CO2 emission; Cirkulär ekonomi; Sorteringsprocess; PVC; Automatisering; CO2-utsläpp;

    Abstract : Background: The industrial economy has been dominated by a one-way production and consumption model. Closing loops for materials has seen an upswing in popularity. The focus though has been on the environmental aspects instead of the economic benefits from implementing closed loops. READ MORE

  5. 4. Evaluation of Scale-up Model for Flotation with Kristineberg Ore

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Adam Isaksson; [2018]
    Keywords : flotation; HSC; Kristineberg; locked cycle; mass balancing; mixed cycle; open circuit; scale-up; blandkrets; flotation; HSC; Kristineberg; sluten krets; massbalansering; öppen krets; uppskalning;

    Abstract : The objectives of this project were to survey the flotation circuit of the Boliden concentrator, mass balance collected data and evaluate a scale-up model for laboratory flotation results. The model assumes that half of the recovery to cleaner middlings in a standard laboratory test would report to the final concentrate if it were done in closed circuit, as is the case in a full-scale plant.
