The phone proved to be a fire hazard and a recall and a final stop in production followed. The exact cause of the explosions, and Samsung’s share therein, however, remain still unclear. Therefore, the founder and director of engineering company Instrumental Anna-Katrina Shedletsky decided the assembly process under the microscope.

insulating layers by design useless

Samsung Galaxy Note 7 trustShe made her team a Galaxy Note 7 to open and analyse any problems. There came the smartphone, under normal use and so the battery can charge. Therefore, pressure is put on the positive and negative cell layer and the insulating layers between them. If these layers are too close to each other and compressed, the insulation virtually useless. The two charged layers start one energy to feed, causing short-circuiting can occur, and the temperature spreads. This results in smoke and explosion.
