Design ‘aggressive’ of the Galaxy Note 7 caused explosions in the … – CNET in Spanish

Instrumental ensures that a design very tight helped that the Note 7 became an exploding bomb.

even Though Samsung has not yet given its final report, which will allow knowing the real causes that gave rise to the Galaxy Note 7 of them to explode in the hands of the users, Instrumental — a company that helps other to elucidate failures in their equipment — he got to work and found that the hazardous internal design of the device was probably the one who turned a terminal potentially dangerous.

In an independent investigation, the company with headquarters in Palo Alto, California, explained on his blog that have been handled several different hypotheses to understand why they would blow up the batteries. First went to the fault in the manufacturing process of Samsung SDI, later — after his replacement — the mobile continued to exploit, then what was happening?

Anna Shedletsky, chief executive of Instrumental, remember that there were different sources and reasons within Samsung that they were trying to explain the explosions: voltage in the battery cells, too much pressure in their manufacture, tapes, insulation poorly placed, among other, but all with a common culprit: the battery. But… what if the battery is not the culprit after all?

The team of Instrumental did not understand why if the battery was the culprit Samsung canceled the product line. That’s why decided to investigate the device and unmount it, coming to a surprising conclusion: in the interest of making the phone more slim and compact, Samsung made the space for the battery too accurate and fair, a decision that would bring consequences that we already know.

Instrumental explains the logic of Sheldon in Big Bang Theory:

“The team [Instrumental] pointed quickly to the layers separator of the battery. The layers of separator allow ions (and energy) flow between the layers of positive and negative, without allowing these layers to touch each other. If the layers of positive and negative ever touch, the energy that flows directly enters in the electrolyte, by heating, causing it to flow more energy and more heat — typically resulting in an explosion.”

But, what does this mean? Although the able internal of the battery were thin, Instrumental, believed that it was enough to keep the energies in her cause, the problem is that the space used for the battery within the Note 7 was very compact, pressed slightly, by placing it in a critical state, which could worsen by external factors such as having the phone in the back pocket of the trouser and sit on top of him — explains the source. This pressure could be sufficient to go damaging the separating layer until it reached the point of no return, making that explode.

Samsung has not given more details since you withdrew world the device, although research continue their course. This same theory of Instrumentation has been supported by other previous reports, although not with this accuracy.
