iPod Touch 2nd Generation Teardown

Teardown

Teardown

Teardowns provide a look inside a device and should not be used as disassembly instructions.

We disassembled this iPod on September 10, 2008.

Edit Step 1 iPod Touch 2nd Generation Teardown  ¶ 

  • The new iPod Touch comes in a smaller, transparent plastic case.

  • Someone asked if we should turn it on, or check out the new software before we took it apart. But we're just a little too eager for that.

Edit Step 2  ¶ 

  • Also included in the box:

    • Earphones

    • USB 2.0 cable

    • Dock adapter

    • Polishing cloth

Edit Step 3  ¶ 

  • As expected, the form has been updated to match the iPhone 3G's shapely curves.

  • Note that the antenna cover is also transformed. It was a rectangle on the 1st Gen Touch.

Edit Step 4  ¶ 

  • Removing the glass display and touch screen digitizer combo.

Image #1

Edit Step 5  ¶ 

  • The bare LCD display.

  • Apple gives the size as 3.5 inches (diagonal) with a 480x320 pixel resolution at 163 pixels per square inch.

Image #1

Edit Step 6  ¶ 

  • There are no screws securing the LCD. Instead, it's held in place with a little double-sided tape.

Image #1

Edit Step 7  ¶ 

  • Removing the metal backing.

  • The battery is held to the backing with two strips of light adhesive, but peels off easily.

Image #1

Edit Step 8  ¶ 

  • Disconnecting the display data cable.

  • Note the residue from the glue holding the battery to the metal backing.

  • This is getting exciting!

Edit Step 9  ¶ 

  • Removing the battery.

  • The WiFi antenna and circuitry are at the bottom of the image, near the thumb.

Image #1

Edit Step 10  ¶ 

  • The large orange cable connects the WiFi antenna (upper left) to the logic board.

  • The size, shape, and characteristics of the cable prevent external noise from interfering with the digital signals as they travel along the device.

  • At the top of the picture above the battery is a metal cover. Underneath the cover is a Broadcom BCM4325 Wi- Fi and Bluetooth chip. Yes, that's right, Bluetooth! Apple has said nothing of this publicly.

    • This particular bluetooth chipset supports BT2.1+EDR. No word yet on whether the one Apple included supports A2DP, which would enable stereo headphones.

    • This chipset also offers FM support, but Apple has displayed zero interest in FM historically, and there are no signs of that trend changing.

    • Part numbers: BCM4325GKWBG CD0825 B76332 P40 SF

Edit Step 11  ¶ 

  • The other side of the wireless circuitry, battery, and logic board.

Image #1

Edit Step 12  ¶ 

  • You can see the dock connector in the center and the headphone jack on the right.

  • Note the small gold "square" above the dock connector. It's actually a conducting spring that rests against the home button. The button acts as a switch, connecting the spring to ground (the dock connector) when it's pressed.

Image #1

Edit Step 13  ¶ 

  • The logic board.

  • We think the brown rectangle in the center is the speaker. It looks like the two wires in the orange ribbon cable on the right of it run to the new volume control dial.

Image #1

Edit Step 14  ¶ 

  • The battery. 3.7 V Lithium-ion polymer, as expected. Apple part number 616-0404. No word yet on the mAh rating.

Image #1

Edit Step 15  ¶ 

  • The logic board again, this time with (what we think is) the speaker removed.

  • The NAND flash memory is a Micron MLC chip: MT29F64G08TAAWP

  • The processor is an Apple-branded Samsung-manufactured ARM with SDRAM on the package, similar to the iPhone processor.

Edit Step 16  ¶ 

  • The end.

Guys, for anyone trying to dissemble their ipor, be very carefull, there is on the top left of the ipod behind the benzel, a very thin cable that connects the benzel to the mother board. If you trying to remove the benzel, do not lift it untill you got the tape out, then carefully lift the benzel, and unplug the cable.

Hey, this is not easy... I've successfully broken the LCD on my ipt2g trying to fix a chip in the glass. the mistake occurred when i was initially popping it open. Ive spent the last two years of my life fixing cellphones for a radio shack and like to consider myself somewhat of an expert on using a pry tool to pop open anything. i made a noob mistake. the kind of simple ^@^^ i did on my first phones. this is simply not easy to do, applying to much force causes a violent opening, not enough and you fidget around until you slip up. go at it with purpose and a good mindset. hold it above something soft and never allow you hands to get sweaty. when you slip and break it, try to keep your cool and not kick a hole in drywall.

U R so right, this is no experience for the faint of heart, I use 3 guitar picks, have been modified, used to use the Nokia tool (I'm Nokia level III certified) stil, I've manage to open 3 of this iPods.

GOOODDD, it's so difficult, please, be very careful, you'll find yourself replacing in the best case scenario the Digitizer.

Good luck

For some reason the multi-touch stopped working after i started to remove the glass. should i pretend that i didn't try and mess with it and send it in for warranty repair or should i try again to take it apart? i don't know why it isn't working whether i nicked something or if somehow the glass isn't touching anymore or something silly like that.

Actually, this warning is written across the top of the page:

"Teardowns provide a look inside a device and should not be used as disassembly instructions."

I luv this website but man what a bad set of instructions for #4. I have been repairing iPhone's for some time now and just tried my first iPod touch using these instructions....not only did I destroy the digitizer, I also destroyed the frame and the lcd! then I went to youtube and for the correct instructions. Im not blaming iFixit but a complete set of instructions would be very helpful!! oh and i still luv this site and I luv the tools I just bought off here!

I dont understand it took me less than 45 mins to replace the digitizer and bezel and the contact was easy to connect btw i got the bezel and digitizer under $30 so look for a good seller!

What is the function of the copper adhesive tape at the top of the LCd screen

ground connection for the LCD, protects from static, etc, may also hold down something underneath!

Very interesting about the Broadcom chip. I wonder why Apple shut that functionality down? I mean, if it has bluetooth I could hookup a headset and use Fring with no problem.

The bluetooth could be a way of tracking people or something i think someone is controlling my IPT because it will close out to the home screen in the middle of a game and that makes me mad anybody know why it does that and if it can be fixed?

That is because Ram inside the device is getting so hot that it is nearly going to overheat so the ipod cleverly shuts down the application so it can free up RAM.

an add: restart the device to really clear the RAM.

I'm having freezing trouble while playing music using the external speaker. When it happens the left bottom of the iPod becomes really hot. It's in the region of that chip of step 13 with the white sticker. Do you know what is that?

Its not because the ram is overheating, the device doesnt generate enough heat for that to even be a factor, its because the ram is getting full.

Nothing about the RAM getting hot. It's just running low on memory. Apps start closing when the device has about less than 10 MB RAM available. But jailbreaking solves this, there are tweaks that allow for expanding virtual memory, e.g. iMemory Enhancer from Gumball Tech repo.

Do you have to dissasemble the whole board just to get to the earphone jack? I need to replace it... it looks like it requires soldering?
