As is normal with recent Apple products, iFixit has given a low repairability score of 3/10 (even though the iPhone 5 proved the exception with 7/10), meaning that opening it up for repairs is pretty much out of the question if you’re an amateur.
The full list of what iFixit discovered on the logic board:
- Apple A5 dual-core processor, with 4 Gb (512 MB) of Mobile DDR2 RAM, denoted by theH9TKNNN4KDBRCR silkscreen label on the A5
- Toshiba THGBX2G8D4JLA01 256 Gb (32 GB) NAND flash
- Apple 3381064 dialog power management IC (similar to the Apple 338S1131)
- Murata 339S0171 Wi-Fi module
- Broadcom BCM5976 touchscreen controller
- Apple 338S1116 is unknown at this time (although it bears a striking resemblance to theApple 338S1117 found in the iPhone 5)
- STMicroelectronics low-power, three-axis gyroscope (AGD3/2229/E5GEK)
- Texas Instruments 27AZ5R1 touchscreen SoC
- STMicroelectronics 2226 DSH CKBEV
- NXP Semiconductors 1608A1
And some of the main points from the teardown:
- While very difficult, opening the case and replacing components is not impossible.
- The battery is flanked by notches that make prying it out of the rear case fairly easy.
- Many components are soldered together, requiring either a very difficult or very expensive repair if any one part breaks.
- The Touch has no external screws. Instead, a combo of clips and adhesive makes it difficult to open the case.
- Cables connected to the logic board run over the top and connect on the bottom, making it difficult to remove the board or disconnect the cables.
