iPad FCC Teardown
An pre-release peek inside the iPad was provided by some photos we uncovered on the FCC's servers.

iPad Wi-Fi
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.

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.

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 <a href="http://www.ats.net/en/index.php/c-12743-Frontpage.html" rel="nofollow">AT&S</a>. 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.

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.

The connector found on the speakers and other components is typical of the connectors seen in MacBook Unibody laptops. Translation: the iPad isn't <em>that</em> cramped for space.

This is very likely the most expensive part of the iPad. It uses expensive IPS (<a href="http://en.wikipedia.org/wiki/TFT_LCD#In-plane_switching_.28IPS.29">in-plane switching</a>) technology and is LED backlit (as opposed to the cheaper TN and CCFL backlit).

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.

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 <a href="http://www.ifixit.com/Teardown/iMac-Intel-27-Inch-Teardown/1236/3#s6704">newest iMacs</a>.

We would have expected the iPad to have a model number in the A13XX range, not A12XX. It's a little tricky to read into this, but our guess: This is indicative of a longer than typical development cycle.
