Update 4/3
We have taken apart a production iPad, with much higher resolution photos.
FCC Photo Analysis
The FCC was kind enough to show the internals of the WiFi iPad before it was released! The photos that they put up had the interesting bits hidden behind grey squares, but we were able to extract the raw files! The WiFi iPad is officially Apple model A1219, while the 3G iPad is A1337.
Apple requested this information stay concealed until August 17th. Clearly, the FCC ignored them.
Note: This is not a traditional iFixit teardown. These photos are not up to our normal quality standards, and it's quite difficult to perform analysis on the low-resolution files. We will be doing a real teardown of the iPad on April 3, the moment we get our pre-ordered units.
Update: 3G iPad
We have uncovered internal photos of the 3G iPad, which won't be released for at least a month! Starting at step 14.
Just want the highlights? Stay tuned to @ifixit for news as we unveil it.

iPad FCC Teardown

Performing analysis as we go. Please help out in the comments! To see highest resolution files, log in and you'll get a large option on each photo.
-
One word of caution: This is likely a preproduction board, and Apple very well may have changed some suppliers since they gave the FCC a sample unit. Take this data with a grain of salt until we are able to analyze a production model tomorrow.
-
It looks like there is a LOT of epoxy holding these chips down to the board. More than we've seen before— Apple is really serious about durability on this thing.

Step 2
¶
-
Bottom of logic board, with and without the EMI shield.
-
We're very happy to report that Apple didn't solder the battery! The iPad uses the same battery attachment system as the iPhone 3G and 3GS.
-
It looks like this board was made by AT&S. It will be interesting to see if their marking remains in the final production board. We haven't seen Apple's PCB manufacturers brand their boards before.
Edit
Step 3
¶
-
This cable carries the signal from the dock connector to the logic board.
-
Never one to waste space, Apple also managed to tack the wifi and bluetooth boards onto this cable.
-
Like some other Apple devices we've seen, the home button is low-tech. There's two contact points that mate with pads on the display assembly. When the button is pressed, the circuit is completed.
-
Notably lacking from this RF/data cable is anything GPS related.
Edit
Step 4
¶
-
Wi-fi and Bluetooth are integrated into a single board. Broadcom has been one of Apple's favorite suppliers recently. It's possible this is the same BCM4329 chip that Apple used in the 3rd Gen Touch.

The bracket shown in the second picture is both a cable clip and a ground point for the WiFi/Bluetooth/cable assembly.
Edit
Step 5
¶
-
A shot of the speaker assembly.
-
The dual speakers provide mono sound. Two small sealed channels direct sound toward three audio ports carved into the bottom edge of the iPad.
-
The connector found on the speakers and other components is typical of the connectors seen in MacBook Unibody laptops. Translation: the iPad isn't that cramped for space.
Edit
Step 6
¶
-
The inner side of the display assembly.
-
The part number is hard to make out, but it looks to be LP097X02. If that's correct, then the display is made by LG-Phillips.
-
This is very likely the most expensive part of the iPad. It uses expensive IPS (in-plane switching) technology and is LED backlit (as opposed to the cheaper TN and CCFL backlit).
-
Display LED barcodes: 1579CN7346569 3225 LG0NJ 'GK65284221MTA', and 5091L-0942B 091214 R51 K319CED5D61R0094B2
Edit
Step 7
¶
-
The battery is quite obvious to pick out of this picture of the rear case (sans display assembly).
-
The 3.75V, 24.8 watt-hour (6.5 Amp hour [!]) battery provides the juice for an advertised 10 hours of use. In contrast, the iPhone 3GS has a 4.51 watt-hour battery and the MacBook Air has a 40 watt-hour battery.
-
The battery seems to integrate two separate 3.75V lithium polymer cells wired in parallel for such ample battery life.
-
The USB power supply had to be enhanced specifically for the iPad. It's a 10W unit manufactured by Foxlink Technology, Ltd., part #A1357 W010A051.

Step 8

-
Some other markings on the battery:
-
APN: 616-0447
-
VPN: DAK 120670-01HH00LH
-
-
The small black box in the second picture is one of the WiFi antennas.
-
Hopefully the WiFi reception will be decent, as the back of the iPad appears to be a single block of aluminum. In addition to the antenna mentioned above, the Apple logo in the center of the rear case also serves as a window to allow for the transmission/reception of RF signals. We saw Apple do this on the newest iMacs.
