Samsung has with the Samsung Galaxy Note 7 is one of the biggest flops in the smartphonehistorie put on the market. 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
She 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.
'Testing battery, Samsung Galaxy Note 7, it took too much time,'
"The testing of batteries is notorious for how much time it takes, and thousands of batteries must be tested to significant results," says Shedletsky. "It is quite possible that Samsung are batterijproductieproces during the development has changed. Then it may be that Samsung, the latest versions of the batteries are not as rigorously tested as the old one."
Also the space that Samsung (not) between the system board and the battery compartment of the Samsung Galaxy Note 7 showed will not have helped. Sometimes this was less than 0.1 mm. On the Z-axis, there was completely no space, while there are at least ten percent of space is supposed to be.
Samsung wants to cause even in 2016 disclosure
Samsung has announced that the own research as to the cause of the explosions. The manufacturer says that it is the cause for 2017 to the outside. The expectation is that the company in February of next year Samsung Galaxy S8 announces.
