Before officially starting to disassemble the details, we revised and improved the specifications provided by Apple. The detailed specifications of iPad Air 2 are as follows:
9.7-inch IPS multi-touch LCD screen with a resolution of 2048*1536 and a pixel density of 264ppi with anti-glare coating
64-bit A8X processor (rumored to be three cores with a clock frequency of 1.5GHz), matching 2GB of memory and M8 coprocessor
8 million rear iSight camera capable of capturing 1080p HD video at 30fps and 720 video at 120fps
1.2 million front camera capable of shooting 720P video
Touch ID fingerprint unlock + barometer + dual microphone + 3 axis gyroscope + accelerometer + ambient light sensor
Support for 802.11ac dual-antenna MIMO WiFi and Bluetooth 4.0
Apple offers 16GB/64GB/128GB onboard storage version
The iPad Air 2 uses a new model sequence of "A15xx", so the WiFi version of the iPad Air 2 model is the A1566.
One of the most important changes to the iPad Air 2 is the addition of the Touch ID fingerprint sensor.
Apple has compressed the thickness of the iPad Air 2 to 6.1mm, even thinner than a pencil.
Well, after introducing the appearance of the fuselage, we officially began dismantling. Use the cymbals very carefully to pick up the screen from the edges. In this process, it is more difficult to remove than the previous generation.
After disassembling, we can see that the connection between the screen and the motherboard is concentrated at the bottom of the screen. This is a very popular change compared to the previous iPad Air, which means that consumers can change the screen or LCD cable more. It's easy and simple.
Touch ID's Sensor Cable is very similar to that used on the iPhone. After the Home button is removed, we can see a separate integrated chip below. According to the observation, this is the NXP Semiconductors' 8416A1 Touch ID sensor.
In the front panel disassembly we found more integrated chips:
Orange: Parade Technology's DP675 LCD Master
Yellow: Texas Instruments' TPS65143A LCD Bias Solution
This is the various small parts we removed, including the speakers, etc.
Remove FaceTime HD camera and 8 million iSight camera
The position and design of the headphone jack are basically the same
Remove the dual antenna
Remove microphone, ambient light sensor
Unfortunately, the logic board is still fixed with glue.
Next we introduce the various components of the logic board:
Red: Apple APL1012 A8X 64-bit processor
Orange: Elpida / Micron Technology's F8164A3MD 8Gb memory (1 GB x 2 = 2 GB)
Yellow: 128 Hynix (16GB) NAND flash memory of SK Hynix H2JTDG8UD1BMR
Green: NXP 65V10 NFC module (same as iPhone 6/iPhone 6 Plus)
Blue: Apple (Cirrus Logic) 338S1213 audio decoder
Purple: NXP Semiconductors LPC18B1UK ARM Cortex-M3 Micro Master (Apple M8 Coprocessor)
Black: Murata 339S02541 Wi-Fi module
carry on:
Red: Maxim Integrated MAX98721BEWV Vibrator
Orange: Broadcom BCM5976 digital controller
Yellow: Texas Instruments TI48WHXDP 343S0583
Green: Fairchild Semiconductor Corporation FDMC 6683 and FDMC 6676BZ
The battery was removed and the data was 27.62 Wh, which was lower than the iPad's 32.9Wh capability.

advantage:
The battery is not soldered to the logic board
The LCD is integrated with the front panel glass. This simplifies the disassembly process.
Disadvantages:
The screen is broken and the maintenance cost is increased, and it is forced to complete the replacement. In addition, damage to the LCD screen is added when disassembling.
Like the previous iPad, the front panel uses glue to increase the risk of broken screens during repair and disassembly.
A large amount of glue is used inside the fuselage for regulation, which means that user maintenance becomes more troublesome.
Main characteristics as below:
- Elaborately manufactures, stable and reliable quality.
- Modular design, small size, save space and greatly improved wiring efficiency.
- Easy to install
- LED action display, each action be absolutely clear to see.
- Custom design to adapt the needs of modern Cnc Machine tools.
