Project Title
Joint development of teaching materials to improve EMC skills of academic staff and postgraduate electronic designers
Website: www.aunp-emctraining.polito.it

Objective
With the worldwide concern of electromagnetic pollution (or commonly known as electromagnetic interference, EMI), the research collaboration facilitates the exchange of design expertise between European and ASEAN universities to reduce the unwanted electromagnetic emission from consumer electronics (PDA, mobile phone, MP3 player, etc)

Collaborators
Nanyang Technological University
Poltechnic of Turin, Italy
University of Hannover, Germany
University of Nottingham, UK
King Mongut's Institute of Technology Ladkrabang, Thailand

Grant
By European Commission as part of ASEAN-EU Universities Network Programme (AUNP)

Research Output
Without design consideration, high-speed circuit packaged on the printed circuit board (PCB) can generated a significant amount of radiated electromagnetic fields across wide frequency spectrum and causes interference to other wireless communication users. To illustrate the important of board-level design for high-speed digital circuit figures 1 and 3 show two different board designs and figures 2 and 4 show the near-field magnetic field intensity measured from the two boards. Figure 5 compares the emission from the poorly and well designed PCBs and the results that poorly designed PCB emits significant emissions compared to well-designed PCB. Figure 6 shows that a poorly designed PCB gives rise significant emissions from the packaged system.
