On September 21, 2012, Apple iPhone 5 was listed in the first batch of nine countries and regions, including: USA, Canada, United Kingdom, France, Germany, Australia, Japan, China Hong Kong, Singapore. At the same time as major mobile phones went to the first listing site, the famous American dismantling website IFIXIT has made detailed dismantles of iPhone 5. Below, let's take a look at it.
First, repeat the specifications of iPhone 5 before dismantling:
- 4 "Retina screen, resolution is 1136x640
- Equipped with Apple A6 chip
- 8 megapixel isight camera
- 8-pin lightning base interface
- Support 4G LTE network
- Run iOS 6 system
Second, the appearance of the iPhone 5 has changed a lot, the most obvious is the bottom, the base interface is getting smaller, the earphone hole is placed at the bottom, and the speaker design has also changed.
Third, the good news is that the iPhone 5 still uses the same screws as iPhone 4 and 4s. The integrated aluminum back shell reminds people of the iPhone 3GS, and the four corners of the iPhone 5 have kept the design of the iPhone 4.
Fourth, what? ! Want to use suction cups? You know, you don't need to use a suction card from the start of the dismantling of 3GS.
The iPhone 5 uses an integrated rear cover design, disassembly needs to start from the screen, unplug it with the suction cup, the same as the iPhone 3GS, not just like the iPhone 4 / 4s, push the back cover.
Because iPhone 5 is removed from the previous, replacing the screen glass is easier. IPHONE 4S demolition screen should pass through 38 steps, iPhone 5 may be the easiest to repair in history.
5. The screen connector is secured to the motherboard with several screws. Unscrew the screw, you can easily open the screen connector very easy to use the chart. The screen can be removed so easy, and once again think of the dismantling of 3GS.
6. After the screen is removed, the internal structure is incorporated into the eye.
7. As an example, let's remove the battery, cut off the part and battery connection. This is also common sense to dismantle the electronic device. Unscrew 3 Phillips screws, remove a metal bracket to disconnect the battery connector from the motherboard.
8. We use the flat chop to pull the battery, the battery uses a binder to fix, typical apple style. iPhone 5's battery has also been improved, the voltage is higher, the battery capacity is larger, we will do a contrast:
- iPhone 5 Battery: 3.8V - 5.45WH - 1440MAH 3G call 8 hours, standby 225 hours
- iPhone 4S battery: 3.7V - 5.3WH - 1432mAh 3G call 8 hours, standby 200 hours
- Galaxy Siii Battery: 3.8V - 7.98WH - 2100MAH 3G call 11 hours 40 points, standby 790 hours
Nine, IPHONE 5 has a variety of metals and metals, and this connector as seen in our figures is a metal frame for connecting a front camera and a metal frame for rear camera. Or maybe the metal frame itself is a certain antenna. It is difficult to say in a time.
Speaking of the antenna, one end of the antenna connector next to the battery is easy to pillage the motherboard. The antenna of this location is in the iPhone 4S is a cellular network of the cell, but in the iPhone 5, I don't know what to do, waiting for further dismantling.
Ten, at the top of the inner cavity, we found several antenna connector, which is firmly fixed inside.
Eleven, after the rendering, we lift the motherboard from the inner cavity. The ISIGHT camera is ligated with the motherboard, and some parts remain in the inner cavity.
Twelve, we finally touched the iPhone 5's good things: chip. Let's take a look at what is the model of the iPhone 5 chip.
Chip is open:
- Red: SkyWorks 77352-15 Power Amplifier Module
- Orange: SWUA 147 228
- Light yellow: Triquint's 686083-1229
- Green: AFEM -7813 power amplifier
- Blue: Skyworks 77491-158
- Purple: A561S K12224 GF010 of Avago Technologies (Anhua High Technology)
- Red: High-pass PM8018 RF Power Management IC
- Orange: Apple 338S1131 Power Management IC
- Light Yellow: Sea Kexi H2JTDG2MBR 128 GB (16 GB) NAND Flash Memory
- Green: Apple 338S1117 Audio Codec
- Blue: Understanding of Semiconductor (ST) L3G4200D (AGD5 / 2235 / G8SBI) low power three-axis gyroscope. Like iPhone 4S, iPad 2 and other leading smartphones.
- Purple: Murata 339S0171 Wi-Fi Module
Thirteen, many parts on the motherboard are fixed with screws and metal frames. It seems that Apple attaches great importance to parts on the motherboard.
14, I saw Apple's A6 processor.
On the other side of the motherboard, close to this chip in the NANO SIM card slot, is the A6 processor used by Apple iPhone 5. The A6 processor CPU performance and graphics card performance are twice, but the core area is reduced by 22%. In actual application, iPhone 5 equipped with A6 processors is faster, such as 2.1 times before the Page load speed reaches the previous, and the Keynote load speed has previously 1.7 times.
Shows the words "apple", is Apple's own chip: Cirrus audio decoder.
Fifteen, the various chips on the motherboard are like the ants climbed on the wooden block.
- LIS331DLH (2233 / DSH / GFGHA) of STMic Semiconductor (ST) ultra low power consumption high performance linear acceleration 3 axis
- BROADCOM BCM5976 touch screen controller
- Apple A6 processor
High-pass MDM9615M LTE modem
- RTR8600 RF MULTI-BAND / MODE transceiver is the same as found in Samsung Galaxy S III.
XVI, 4G LTE chip of iPhone 5, can be definitely QUALCOMM MDM9615M
Popular: MDM9615 is a high-pass launch support LTE (FDD and TDD), Dual carrier HSPA +, EV-DO version B and TDM (MDM) chips, which will be manufactured in 28 nano-node technology, MDM9600 product range highly optimized successive products. The chipset has improved in modem performance, power consumption, motherboard and BOM cost.
17. The chip of the touchpad controller is a Broadcom BCM5976.
Apple uses a touch panel controller with MacBook Air. Plus the Touch screen controller of Texas Instruments, created the touch input of the iPhone 5 Retina screen.
Eighteen, after anatomy the motherboard, we turn our attention to the back shell. Next, remove the LightNing base interface assembly, including headset holes and speakers. Look at this part, Apple has to narrow the base interface, and this component is not a base interface of the 30-pin. The microphone at the bottom is crowded between the headphone holes and the Light Ning base interface, hiding behind the second speaker hole.
Let's take a look at these parts in close proximity to the base interface, which is indeed 8-pin, although Apple official does not explain in detail, but two needles are used to power and ground, other 6-pin still don't know what to use .
19. Although there are still a few parts, there is no demolition, but it is a back shell, or it can feel very light. There are more light, we have known the equipment with high precision, and the entire back shell is just a little bit better than the back of the iPhone 4S.
Twenty, the vibration motor adopts the technique of stress contact welding, saving the trouble of opening the small connector. iPhone 4S is a linear motor, different from iPhone 4s, iPhone 5 is used back to previously used rotation motors. Once we also appreciate the linear motor of Apple with noise, now we scratched the head, don't understand how the apple is back.
Twenty-one, the handset is two screws and connectors to fix the screen, and the middle is separated. The iPhone 4S speaker is originally pasted on a fragile power supply, and it needs to be meticulous. IPHONE 5 speakers are easy to play from the screen integration, and another reflection is easy to repair.
Twenty-two, the HOME button of the iPhone 5 is placed on an integrated metal bracket and can withstand more frequent pressing. The iPhone 4 and 4S users' home is easy to fail, and they don't dare to trade the HOME key themselves. The iPhone 5 not only prolongs the life of the HOME button, but also replaces it. It is not so troublesome.
Twenty-three, the front part of the screen integration is surprising, unscrewing several screws. This piece should be a baffle with a heat dissipation function, and the spring contact piece next to the screw also implies that the plate is also grounded.
Twenty-four, should be read by the reader, we test whether the iPhone's black coat is easily worn. We have found that the edges are very strong, but the four corners are easy to wear, it is best to use protective sleeves and need more careless time.
Twenty-five, one of the big selling points of up to 8 megapixels is an isight camera. From the camera assembly, ISIGHT has a little difference with last year, but it is actually a weak light shooting of Isight, and the image capture is faster.
Apple claims that the lens of the camera uses sapphire crystals. We tried to use steel scratches to scrape the outer layer and have no effect. The outer layer of the lens is really hard and scratched.
Twenty-six, now we can see the microphone of the iPhone 5, just as Apple promises, Apple has three microphones for iPhone 5, which is mainly used to serve FaceTime and hands-free features.
The microphone in the back may be used for background noise reduction.
Summarize
Finally, IFIXIT gives the repair to the iPhone 5 into 7 points (10 points to the most easy to repair), the iPhone 5's repair is difficult to reduce the iPhone4 / 4S, which is much reduced.
- Because the disassembly of iPhone 5 is neutralized from the front, so replacing the screen glass is easier. You know, most of the IPHONE repair cases are damaged by screen.
- After being removed by the front panel, you can take a little out of the battery.
- iPhone5 uses screws that have appeared on iPhone4 / 4s.
- Front plate glass, digital plate, and LCD panel are integrated, and many minor originals are welded to a strip cable, which improves maintenance costs.
