As predictable as the sun rising somewhere over east Japan, the iFixit crew have put their tools and wits to the task of deconstructing the latest generation of iPod touch. Although they tear apart it softly, the "scence" is still so shocking after iPod had been torn down. Lte's enjoy this process. If you can't control yourself, maybe just take out your iPod Touch and follow us. Suggest no!
2.There are two cables securing the display assembly to the logic board. One is easy to disconnect, but the other is more challenging. The thin black cable connects beneath the logic board. That means that replacing the display assembly will definitely not be trivial.
3.rive the screw
4.open this metal plate
5.We can see the battery lists a capacity of 3.44 Watt-hours.
6.In a first for the iPod Touch line, the headphone jack is not soldered to the logic board.
7.There's one screw, one connector, and the headphone jack lifts out.
8.It took a bit of prying to lift the battery and logic board out of the casing, but unfortunately the headphone/sleep button control ribbon cable is both soldered to the logic board and glued to the outer case.
9.
10.After wrangling the logic board/battery/display assembly out of the rear panel, we can finally access the screws holding the volume button cover and the sleep button down.
11.After a good bit of anxiety-filled scraping with a metal spudger, the ribbon cable is finally free from the rear panel.
13.After removing a loop of copper tape around the digitizer connector, the display assembly can finally be separated from the logic board.
14.A copper shield fastened to the back of the battery can also be removed at this point. This step is so risk and may be you can piece your iPod Touch together agian, do it carefully!
15.At this point, the rear facing camera can be disconnected from the logic board.
16.The front-facing camera is readily accessible and can be disconnected from the logic board at this point.
17.Next, we disconnected the Touch's singular external antenna.
18.Open it, and you will find some serious chips.
Conclusion
iPod Touch 4th Generation Repairability: 4 out of 10 (10 is easiest to repair)
Good: Opening the device is pretty straightforward, as long as you have a heat gun and some iPod Touch opening tools handy.
Good: The headphone jack is not soldered to the logic board, a first for the iPod Touch line.
Bad: The front glass and LCD are permanently fused together, increasing the cost of repairing broken front glass.
Bad: Removing the display completely requires removing the logic board
Bad: Apple soldered the volume button and sleep button cable to the logic board. The previous Touch had a ZIF connector. This makes removing logic board very difficult.
Bad: The battery is still soldered to the logic board, just like previous models.
