‘iFixIt’ tears down the iPad 2


“iFixIt’ has torn down the iPad 2. You can read all about it at and or see a video at ; however, here is the summary from “iFixIt”:

“Prior to starting the teardown, we guessed that the glass front panel was no longer held in place by tabs. We were correct. The new tapered edge on the iPad 2 prevents any kind of tabs from being used; instead, Apple engineers used generous helpings of adhesive to keep the front glass in place. Consequently, the front panel is very difficult to remove — it’s nearly impossible to open the iPad 2 without shattering the glass. We’ll be working hard in the forthcoming weeks to provide a solution to this problem, but for now: please don’t open your iPad 2.

“The iPad 2 received a 4 out of 10 repairability score, mainly for the extreme difficulty of accessing anything inside. But if you do manage to get in, you’ll find that all screws are of the Phillips variety, and the LCD can be easily taken out once you separate it from the front panel glass (but separating it from the glass is difficult, of course).”

“We did a quick glass and LCD thickness comparison:

“iPad 1: lcd = 3.2 mm glass = .85 mm

“iPad 2: lcd = 2.4 mm glass = .62 mm

“The thickness of these components — especially that of the glass — could drastically reduce the durability of the device, especially the glass’ resistance to shattering. We’ll see in due time if the percentage of folks with broken iPad 2 front glass is dramatically different than that of the original iPad.

“Lifting off the LCD exposes the iPad 2’s battery. We found a 3.8V, 25 watt-hour unit. That’s just a hair more than the original iPad’s 24.8 watt-hours, so any improved battery performance should be attributed to software and other hardware improvements.

” We confirmed via software that the iPad 2 indeed has 512 MB of RAM.

“The markings on the 1 GHz Apple A5 dual-core processor appear to be Samsung’s, but Chipworks will investigate in the forthcoming days to find out for sure.

“Other components that power the iPad 2: Toshiba TH58NVG7D2FLA89 16GB NAND Flash; Broadcom BCM5973KFBGH Microcontroller; Broadcom BCM5974 CKFBGH capacitative touchscreen controller; Texas Instruments CD3240B0 11AZ4JT touchscreen line driver; Broadcom BCM43291HKUBC Wi-Fi/Bluetooth/FM tuner combo chip; S6T2MLC N33C50V Power Management IC; ST Micro AGD8 2103 gyroscope; and ST Micro LIS331DLH accelerometer.”

“There’s also an Apple-branded 338S0940 A0BZ1101 SGP chip. This looks like the Cirrus audio codec Chipworks found in the Verizon iPhone, but they’ll have to get it off the board to make sure!”
