    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. Embedded boundary scan for test & debug

    University essay from Institutionen för datavetenskap

    Author : Aijaz Baig; [2009]
    Keywords : boundary scan; JTAG; embedded; test;

    Abstract : The boundary scan standard which has been in existence since the early nineties is widely used to test printed circuit boards (PCB). It is primarily aimed at providing increased physical test access to surface mounted devices on printed circuit boards (PCB). READ MORE

  4. 3. Evaluation and Simulation of Black-box Arc Models for High-Voltage Circuit-Breakers

    University essay from Institutionen för systemteknik

    Author : Niklas Gustavsson; [2004]
    Keywords : Reglerteknik; Arc model; ATP; Circuit-breaker; High voltage; Reglerteknik;

    Abstract : The task for this Master thesis was to evaluate different black-box arc models for circuit-breakers with the purpose of finding criteria for the breaking ability. A black-box model is a model that requires no knowledge from the user of the underlying physical processes. READ MORE
