How To Disassemble Ipad 4
How to disassemble the 6th generation Apple iPod Nano player Roman Paulov’s blogofolio
Taking apart the 6th generation iPod Nano player. It has model number A1366 and capacities of 8 or 16 GB.
This guide is a translation of the article: https://www.Ifixit.com/Teardown/iPod-Nano-6th-Generation-Teardown/3563/1.
- Use tweezers to unlock the microphone connector.
Gently grasp the microphone connector and separate it from the board.
Remove the microphone along with the connector.
Some versions combine the microphone, volume buttons and power button into a single assembly.
The microphone is labeled S1055.
- In the photo we compare the disassembled and the previous model. On ours we see: the lack of a rear camera connector.
- We use our iOpener to loosen the adhesive holding the front panel to the back case. This method avoids damage to the screen, preheat the iOpener in a microwave oven at maximum temperature for one to one and a half minutes, wrapped in a damp paper towel. Do not burn yourself.
Place the bag around the iPod to loosen the glue.
The suction cup will help us to easily separate the front panel from the back wall. Center it on the iPod, with the edge centered on the power button. Pull out and remove the front panel.
Carefully separate the storage device. It is fixed with glue. To peel off, use a plastic spatula over the grooves in the battery compartment.
Under it, on the back panel, we see orange and black ribbons.
Separate the black tape along with the power button and the bracket holding it.
Finally, we got to the new iPod Nano with Multi-Touch support!
A shiny new Nano player came to our doorstep early in the morning, and we can’t wait to see what’s inside.
Unlike the 4th generation iPod Shuffle, the Nano box is more or less the right size for it.
Apple Model Number: A1366.
Ipod Nano, Meet iPod Nano.
Despite the same price as the previous model ( 149 and 179 for the 8GB and 16GB models), the new Nano has many differences.
Gone is the time of the wheel of buttons, cameras and playback.
It’s time for the multi-touch screen [!]. The Nano also has volume buttons and a sleep button.
In addition, the form factor has been slightly revised.
- 5th Gen Nano measures 9.1 x 3.8 x0.6 cm and weighs 36.3 g.
- The 6th Gen Nano measures 3.8 x 4.3 x 0.9 cm and weighs 21 g.
The new Nano occupies 67% of the volume of its predecessor, although its dimensions are less than half less.
The new Nano looks more like a Shuffle with a screen than a multi-touch Nano. They have a very similar body design.
Since the screws are nowhere to be seen, we decided to first resort to heating to soften the adhesive base.
Our hot air gun helped to soften the glue that holds the display.
By gently prying the perimeter of the iPod Nano display with a plastic opening tool, we were able to separate it from the device.
And so we opened the Nano player like a tiny book.
The front glass of the Nano protrudes approximately 0.3 mm from the flat surface of the case. You will ask why? Possibly due to the headphone jack. Apple wanted to make the device as thin as possible, so that the bends of the edges fit closely to the glass, the body would have to be made thicker. But preference was given to slightly protruding glass.
Now it’s time to see what’s inside the player!
We bend to the side the display, which is still attached to the cable, take our trusty Phillips screwdriver # 00 and quickly unscrew the 2 screws securing the electromagnetic shields.
The inside of the Nano is very much like the new Shuffle; the space is divided in half between the tiny motherboard and the battery.
Disconnect the digitizer and display data cables, after which you can remove the display.
The 1.54-inch LCD display supports multi-touch recognition, although how you can comfortably fit more than one finger on the display is a mystery.
The LCD has a resolution of 240 x 240 pixels. This means a rather boring 1: 1 aspect ratio. The screen is also significantly smaller compared to the 2.2-inch 240 x 376-pixel display on the 5th Gen Nano player.
Like its sister devices iPhone 4 and iPod Touch, the touch panel, LCD and front glass are inseparably bonded.
The Nano display module is 2.27mm thick. It’s even thinner than the 2.93mm of the new iPod Touch and the 3.05mm of the iPhone 4.
The Nano has a pixel density of 220 pixels per inch (PPI), the highest pixel density in an Apple device outside of the iPhone 4 / iPod Touch 4th generation. That’s almost double the iPad’s meager 132 PPI!
Now you need to disconnect one more cable connector. This time. The headphone jack cable and the power / volume buttons.
Using connectors instead of soldering makes repairing the device much easier. Thanks, Apple!
We unscrew the screw that secures the motherboard, and finally, you can pull it out.
In principle, the battery can be pry off with a plastic tool for disassembling the cases, but, unfortunately, it is soldered to the motherboard.
The 3.7v Li-ion battery is rated at 0.39wh for up to 24 hours of continuous music playback.
Translated into ampere hours, the Nano’s battery capacity is 105 mAh; for comparison. The battery capacity of the Shuffle 51 mAh.
This iPod Nano’s battery only has 2 wires, red and black. All other iPod Nano models had 3 wires. The third wire usually went to the thermistor. Apparently the iPod Nano battery is small enough and the charging speed is slow enough that there is no overheating problem.
The pins of the headphone jack and buttons are connected by a long, thin ribbon cable that runs along the inner edge of the Nano case.
The button contacts are attached to the top edge of the case with 4 very small screws.
Unscrew another screw and use a plastic opening tool to remove the headphone jack.
The headphone jack, volume buttons and sleep button are all on the same ribbon cable that wraps around the Nano from the inside.
Like the 5th generation model, the new Nano uses headphones as an antenna for the FM radio. Over, any headphones will work as an antenna.
Hardware volume control outside the case is a new, albeit handy, addition to the Nano.
Interesting chips on the motherboard:
- Toshiba TH58NVG6E2FLA4C 8 GB NAND Flash (circled in red)
- Apple 33850859 C0E111022 (circled in turquoise)
- Dialog D1830B Power Controller (Apple 338S0783-B1 10298HLS) (orange outlined)
- Fm receiver 0650 D0UY 027 (circled in yellow)
- Apple 339S0104 YGC7 1031 K4X51323P1 YRF 020A3 ARM N2HXHZMP 4 1031 (circled in blue)
- 357589071025 A04 629749 (outlined in pink)
Unscrew 3 more screws securing the new iPod Nano clip.
A total of 11 screws are obtained. Quite a lot for such a small device.
6th Generation Apple iPod Nano Easy to Repair: 5 out of 10 (10 is easiest to repair).
- Ribbon connectors make it easy to disconnect the display and headphone jack from the motherboard connector.
- After removing the display, the rest of the device is easily disassembled.
- The display is very difficult to remove without a hair dryer.
- The battery is soldered to the motherboard, making it unnecessarily difficult to replace.

So, let’s take a look at the brand new iPad 3 bought in Melbourne (Australia).
- Apple A5X dual-core processor
- 9.7-inch LED-backlit LCD Retina display with 2048×1536 resolution.
- Quad-core photographic processor
- Flash memory 16, 32 or 64 GB
- 5 MP HD rear camera
It’s time to start disassembling! What an expert will need to disassemble the latest iPad at midnight, across the world?
Here’s what: a set of professional tools, good old Red Bull and, of course, an iPad 3 tablet.
Everything should work out, it’s not for nothing that I had to fly from America to Australia for the debut of this device.
Wow, what is this iPad model? Ipad 2 3G? Ipad 3 4G? Ipad N (N1) G?
Fortunately, the model has a unique number, unlike some other Apple products. Model number. A1430.
So this is what the back panel of the new “new iPad” looks like. Reminds nothing?
The 5-megapixel iSight camera on the back of the tablet is equipped with autofocus, face detection, HD-1080p recording and stabilization while shooting. This is a clear improvement over last year’s 0.7 megapixel camera.
Retina display off with a resolution of 2048 × 1536 pixels. Is not so impressive anymore, and you can calmly get down to business.
Using a hot air gun, guitar picks and plastic tools for disassembling the cases, we can easily remove the front panel with great effort.
Like its predecessor, the new iPad is very difficult to disassemble. The glass is glued to the body, making it very difficult to repair and replace the battery.
And since Apple sold about a million devices only on the first day of release, can you imagine what a blow to the environment such an unfortunate design will cause?
Of course, iPad can be repaired. With great difficulty.
Heavy-duty display removable with heavy-duty rubber suction cups.
So the first legally acquired iPad 3 became the world’s first open iPad.
And this clearly does not please him.
The following pictures show the professional disassembly tools offered by iFixit.
Well, the display is screwed to the case. Fortunately, this is not a problem for top-class screw looters.
Instead of sitting and admiring the high-resolution display, we detach it. Why? Because we like to do disassembly.
And we shoot the display despite desperate protests of all 3,145,728 pixels.
Time to cut the umbilical cord and disconnect the display and touch screen cable.
The display connectors on iPad 2 and iPad 3 are different. They are incompatible. At the moment.
Based on the model number on the back of the 9.7-inch LCD panel, it is manufactured by Samsung.
We found 3 mysterious matrix barcodes next to the numbers.
Screws and connectors, screws and connectors, motherboard keep you ready!
Well, okay, our poetry is not very good, but everything is fine with the disassembly. We arm ourselves with a plastic spatula and a screwdriver and go!
Come on, iPad. Please let go of the motherboard!
Thank you Siri! Siri? Are you here? (and in response. Silence.)
Hooray, we removed the motherboard!
With the help of the magic powder that remained with us after disassembling the iPhone 4S phone, with a slight movement of the hand we remove the electromagnetic shields and send them flying, while we ourselves admire the microcircuits.
Chips, chips, chips. Here’s what’s on the motherboard on the opposite side to the processor:
- Texas Instruments CD3240 chip (circled in red)
- Broadcom BCM4330 802.11a / b / g / n wireless chip with built-in Bluetooth 4.0hs controller and FM transceiver (orange circled)
- 2 x 512 MB Elpida LP DDR2 RAM = 1 GB DRAM 64-bit (highlighted in yellow)
- Fairchild FDMC 6683 Chip (circled in turquoise)
- Broadcom BCM5973 I / O Controller (outlined in blue)
- Broadcom BCM5974 microprocessor (outlined in pink)
- Apple 338S0987 chip (Cirrus Logic audio codec) (circled in black)
. And here’s what’s on the other end of the motherboard:
- Qualcomm PM8028 Power Controller (circled in red)
- Qualcomm RTR8600 Multiband / Multimode RF Transceiver for 3G and 4GLTE Networks (Orange Outline)
- Toshiba Y0A0000 memory controller (outlined in yellow)
- Triquint TQM7M5013 4-Way Linear Power Amplifier (circled in turquoise)
- Avago A5904 chip (circled in blue)
- Skyworks dock SKY77468-17 (pink outlined)
Using a plastic spatula, we get to the A5X processor. Here it is, in all its glory.
Like the A5, the A5X has a 1 GHz dual-core processor. The “X” was added at the end thanks to a new photographic processor, which Apple claims is even better than the Nvidia Tegra 3.
This particular chip was produced in the first week of 2012. Maybe our iPad marks the beginning of the end of the world.
Turning the motherboard over:
- Apple A5X dual-core processor (circled in red)
- Apple 343S0561. This IC is similar to the updated version of the 343S052 IC we found in the iPad 2 and serves as a power controller (circled in orange).
- Nand memory, part number THGVX1G7D2GLA08. 16gb 24nm Toshiba MLC Flash (circled in yellow)
- Qualcomm MDM9600. 3g and 4G Wireless Modem (circled in turquoise)
- Skyworks 77469 chip (circled in blue)
- Avago A7792 chip (outlined in pink)
Many thanks to colleagues from the Chipworks website for their help in identifying the chips!
We see an inverted A5X processor die mounted on a PCB.
You can argue that the cover of the A5X processor serves as a heatsink, judging by the fact that it is covered with thermal paste from the bottom, and covered with a thermal pad on top.
The A5X is 12.82mm x 12.71mm (162mm ^ 2), 36% larger than the A5.
Like most tablets, the iPad 3 is really just a giant battery.
We pry the battery with a plastic spatula and remove it for further study.
While the iPad 2 has a whopping 25Wh lithium-ion battery, the iPad 3 has raised the ante to 42.5wh.
3.7v and an estimated runtime of 10 hours (9 on mobile) is comparable to the iPad 2, but we assume an additional 17.5wh of power is used to power the increased RAM and significantly improved photographic core.
The battery consists of 3 cells, each measuring approximately 12.5 cm x 6.5 cm x 4 mm. Ipad 2 battery cells were 10.8cm x 6.3cm x 2.7mm.
Each battery cell is labeled 3.78 V and 14.60 Wh. They are also adorned with matrix barcodes and wonderful lettering: 741-0065-A P11GG9-01-F01TS. Fallout!
Energy density is about the same as in iPad 2. About 0.0014 Wh / mm3.
Apple has physically increased the size of each element by about 70%, which explains the jump from 25 to 42 Wh.
Apple claims the new iPad is environmentally friendly thanks to its “recyclable aluminum and glass design.” The materials may be recyclable, but the assembled device is not. We spoke with Steve Skurnak, President of SIMS Recycling Solutions, one of the largest electronics recycling companies in the world. Here’s what he said: “Sealed devices make it difficult to remove the battery. In terms of reuse, hazardous components [like batteries] should be easy to remove. “.
We continue to disassemble, and only the frame of the once mighty iPad remains.
But since we are real vultures, we pounce on the remains of the aluminum beast. And first of all, the dock connector.
It looks like the pinout of the dock connector is the same as on the iPad 2, but the interchangeability of these connectors remains to be determined.
Awful, disgusting screws! Get out and let us extract the antenna in peace.
Get away, train! Let us see the micro SIM card slot.
Like other micro-SIM iPads, the iPad 3 4G has a user-accessible micro-SIM slot that can be removed with a tool.
The headphone jack and one of the many wireless antennas are removable as a single module. Bummer.
Hey hello! Introducing the iSight camera. What are your characteristics there? So, 5-element lens, infrared filter, auto-exposure. That’s it, iSight, that’s enough, we are confused.
Update: Colleagues at Chipworks found that the main camera is actually the exact same sensor as the iPhone 4: Omnivision OV5650 CMOS sensor, 1.75 micron pixel pitch, 5MP backlit.
The second camera also uses an Omnivision sensor, OV297AA. Cmos sensor 0.3 MP, pixel pitch 3.0 microns.
Removing small parts like the front camera and antenna.
The front-facing camera is great for small shots, chat, or to fix your hair.
A whole bunch of all kinds of buttons and switches! Just admire.
The next victim on our list is the speaker module. Goodbye speakers!
Ipad 3 Repair Ease: 2 out of 10 (10 is easiest to repair).
- The LCD is easily removable after removing the bezel.
- The battery is not soldered to the system board, making replacement slightly easier.
- Just like the iPad 2, the bezel is glued to the case, which greatly increases the chances of breaking the glass when trying to remove it.
- A huge, huge amount of glue! Virtually all components are glued, including the battery, which can burst into flames if damaged.
- The LCD is glued to the front panel with adhesive foam tape, which greatly increases the chance of cracking when disassembled.
- The connector on the front panel cannot be reached without removing the display.
