Abstract
In this paper, we analyzed damage patterns of a folder type mobile phone caused by microwave-irradiation, to find an accurate fire cause and to investigate deliberate broken of mobile phone for obtaining pecuniary advantage by deception. In order to analyze broken patterns, we irradiated a mobile phone with microwave using by 2.45 GHz microwave oven. Form the experiment results, damage patterns of mobile phone have been tendency toward heavy broken patterns depending on time of microwave-irradiated. Distinctively, folder hinge and intenna(Planar Inverted-F Antenna) were heavy broken in compare with battery, enclosure and so on. The enclosure of mobile phone became just thermo-metamorphism and the battery was not broken such as explosion.
