1. Kretskortskonstruktion
Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : EMC (electromagnetic compatibility) is an important aspect to consider in circuit boarddesign as a product must not be interfered with or interfere with other products throughelectromagnetic radiation. During the development of a prototype, it is primarily important toachieve functionality, and the EMC aspect may only come into play when the product istransitioning from prototype to finished product.

2. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. Embedded boundary scan for test & debug
Master-uppsats, Institutionen för datavetenskapSammanfattning : 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). LÄS MER
4. Evaluation and Simulation of Black-box Arc Models for High-Voltage Circuit-Breakers
Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknikSammanfattning : 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. LÄS MER
