The iPhone 6s is already pretty slim at 7.1mm, yet Apple is said to make the iPhone 7 even thinner, according to the rumor mill, by eschewing the 3.5mm audio jack altogether, replacing it with a Lightning port connector for the bundled in-ear headphones. That's not the only trick Apple would employ to reach the speculated 6mm and change thickness of the new iPhone, though, claims Korean media.
iPhone 7, resulting in a more compact motherboard and antenna area, leaving extra space inside for an eventual larger battery to sprawl, despite the purported thinner chassis. This packaging technology fuses the silicon chips and the semiconductor compounds together, resulting in more powerful yet more compact chippery.Apparently, Apple may be using the so-called "fan-out" chip packaging method for the first time in a handset with the
All welcome changes, but not the only benefits of the "fan-out" tech. It is actually the ASM (Antenna Switching Module) that will see advantages of merging the silicon chip with GaAs (Gallium Arsenide) semiconductor compound, as is tipped to happen in the iPhone 7. Gallium arsenide is good for receiving high-frequency signals with little interference, improving on the signal penetration, but so far two modules were needed on the circuit board, whereas merging them in one with "fan-out" will now save space, yet have the same level of antenna efficiency.
The source of this rumor are, as usual, a few suppliers - Apple has allegedly given big orders to ASM makers from Japan and other places that produce the antenna units with "fan-out" technology. In addition, TSMC itself has mentioned that it is producing a big part of its 16nm wafers with "fan-out" for one sole customer. It stopped short of naming Apple, but by now we've heard numerous times that the foundry is tasked with producing the upcoming A10 chipset that will be used for the iPhone 7. Apple is said to use this method for other motherboard components inside the new iPhones, too, so we can't wait to see the final result this fall or thereabouts.
