Magnetic Force Imaging
*Aim : Non destructive FA is more and more required. Different kind of magnetic sensors exist on the market, which present different characteristic. Current mapping using very low field magnetic sensors is explored. *Expected sensibility : better than 1 µT for PCB imaging (2.5 mA and 500µm). better than 10 nT for IC imaging (5µA and 100µm). *”factor of goodness” : sensibility sensor size working distance Olivier CREPEL
