A Look at iPhone 5′s Unibody Design [Report]

We have already seen many back covers and prototypes of iPhone 5 selling on different Chinese websites and we are pretty sure that the next iPhone will be larger, thinner and lighter than the previous iPhone 4 and 4S. Well, this time an industrial analyst, Don Lehman has examined the leaked cases and backs of the iPhone 5 and concluded that the next-gen iPhone will be lighter, slimmer and even much stronger than iPhone 4 and 4S.

The analyst has also reported that Apple has changed the Antenna design of the iPhone 5. If we think back at 2010, the GSM iPhone 4, the “Antennagate problem became very viral for many users. So, now Apple will use the Antenna design between the iPhone 4 GSM and CDMA.

According to Don Lehman:

The leaked design has three pieces of metal instead of four. It still has two U-shaped pieces at the top and bottom, but this time the two flat sides become one single piece of metal that also comprises the back of the device. That single piece of metal is the unibody backplate. 

The same properties that unibody designs give to Apple’s laptops apply to this design as well: stronger, lighter, and thinner. You can see from this picture the tool path of the CNC machine that made the unibody backplate of this design. The tool path sort of looks like the lines that are made when a farmer plows a field. This started out as a single block of metal and the CNC carved that metal out until you have what you see here.

Don also analyze that bosses are machined of the single rear shell piece such that to provide enormous strength and reduce the thickness of iPhone. While Glass or plastic windows of the Wi-Fi, GPS, Bluetooth and NFC technology will be present on the top and bottom of the back of the iPhone 5. Similarly, once cell antenna will be present on the top and the other at the bottom. However, Apple will make the back thinner and weight will be also reduced. But it will surely have the increase strength.

Update : Apple Media event has been ended and iPhone 5 has been released – here’s iPhone 5 features and Specs.
