    Congratulations!!!

    I Love the iFixit!!! It's is always a pleasure to follow the site!!!

    Ok, so I presume there is a lot of free sapce to make some mookup's in the iPad as like as to "add" a full USB connector and also a SD Card or MicroSD card connector.

    So, is there any body available to please us with a "How To"???

    Would be nice!!!

    On the iPhone 3G and 3GS, Apple was nice enough to use visible screws instead of tabs. Since the iPad lacks screws and is held together with tabs, I think it's unlikely you could get the iPad apart with a single suction cup. We'll be working on figuring out the least invasive way to get your iPad opened up.

    The A4 is likely a multi-die package, with the CPU and DRAM mounted on the same substrate. (High-speed logic and high-density memory require fabrication processes that are less-than-optimal for the other.) That would explain the multiple part numbers. Other folks have pointed out that the K4X2G643GE part number is for a 2Gb (256MB) part.

    Sheesh! 2 Gigabits is 512 MB? Since when is a Byte only 4 bits? It's 256 MB of RAM and that goes in line with reports from developers who had their apps rejected for memory warning crashes, which occur at a comparable RAM usage as on the iPhone 3GS.

    Ok we're looking at two chips here, i get it. 2 Gigabits per chip times two equals 512 MB. But why are developers seeing only the same free amount of memory as on the iPhone 3GS? Why would the iPad keep about 256 MB to itself?

    I guess given the software reports, there's no holding out hope that the 2Gb part number refers to each individual DRAM chip inside the A4 rather than the 2 combined?

    In any case, can you confirm my interpretation of Samsung's nomenclature that the "64" in K4X2G643GE refers to a 64-bit memory bus width? If that is so, that means that regardless of RAM amount, the iPad has double the memory bandwidth of the iPhone and other smartphones which Anandtech reported to have 32-bit memory buses in their Google Nexus One review. The doubled memory bandwidth would benefit not only the CPU but also the GPU which shares system memory and bandwidth.

    It seems A4 is not (yet) revolutionary product, but upgraded version of A8 based processor found in iPhone 3GS.

    On FCC RAW data logic board photos of iPad it is clearly seen that the processor, not yet marked as A4 but in old, iPhone style, is manufactured during week 49 of 2009.

    In addition, Apple part number of A4, APL0398, is quite similar (upgraded?) to original iPhone 3GS processor PN APL0298.

    I was confused about the amount of memory, but the pictures on the Chipworks page cleared that up.

    The number in the outside, K4X2G643GE, indicates 2 gigabits (256MB) total, 64 bits wide. The numbers on the inside, K4X1G323PE + K4X1G323PE, indicate 1 gigabit (128 MB) on each die, 32 bits wide.

    Also, next to the light-sensor connector at the top, you'll see empty spaces for a tiny 25-pin BGA chip and a 6-pin connector. If I had to hazard a guess as to their purpose, I'd say the chip is camera-related, and perhaps converts the raw camera output to USB, and the 6-pin connector brings out the USB input for testing.

    Can anyone measure the pad pitch of the BGA? If it's 0.50mm, it would fit the SMSC USB3311 or another in-family. The 24-pin connector there would support the 12 signals for ULPI to a camera.

    Heyyyyy, the FCC got a camera with theirs! And they've got the BGA chip and connector populated with it. Apple's holding out on us! They probably wanted to save something for version 2. Here's from Step 1 of the FCC pictures. And Step 18 shows the camera loud and clear.

    A friend of mine remarked to me: "First thing I thought of when I saw the iPad was that it seemed like a nice alarm clock.

    Well, I take it back. IT HAS NO F-ING CLOCK BUILTIN!

    http://www.guardian.co.uk/technology/201...

    It cannot wake from sleep on an internal alarm. Apparently it cannot

    run an alarm clock in background!"

    I couldn't believe that - what, no permanently running RTC? To save parts costing under a dollar, they made a big expensive computing device that doesn't know the time and date?

    But now I'm looking at that main board more closely, hmmm.... I don't see any 32768Hz crystal. You know the ones - a tiny metal cylinder with two leads, as found in every watch, cheap desk clock, and computing device that, you know, CAN tell the time.

    Just possibly the crystal could be in a small rectangular ceramic case, but I don't see any candidates for that either.

    This is completely ... beyond absurd. Bizarre. What were they thinking? It really makes me wonder...

    With Steve Jobs being on death's door and all, I wonder if he's maybe doing a big 'fu*k youse all' farewell gesture? And the iPad (feminine hygiene name _intended_) is the raised finger?

    In six months, all iPads brick themselves, with a permanent, unremovable goatse image. Signed "So long suckers! Thanks for all the cash. S Jobs" And then a deliberate internal short circuit makes the battery explode.

    Fortunately, that worry can't be real. Since the iPad doesn't know the date. Err... unless it's online, I suppose.

    The original iPhone's back was a stamped aluminum case plus a glued-on cast metal frame, along with a tack-welded metal screw bracket. The buttons and other pieces screwed into the frame that was glued onto the back. The main problem with this was that all the Chinese replacement parts makers advertising on Ebay were selling the plain back case without the frame and other parts necessary to use it. Also, sometimes the frame would become partially unglued from the back when you opened the phone.

    The iPad should not have these issues, as the back is a solid hunk of aluminum (though it does have some tack-welded screw mounts). I do foresee iFixit and others selling lots of replacement screen clips that hold the unit together, though.

    There is no hardware to support FM transmission (only receive) and just because the Broadcom chip has an FM demodulator, doesn't mean that you have enough hardware to support FM reception. You need a substantial set of antenna tuning components, not to mention the antenna itself.

    You mention that the ipad has 2 3.7 volt li-poly batteries. Other wise know as li-po.

    Li-po as I know it is still fairly unstable and if the voltage per cell drops to low it can cause damage to the cell.

    I rac RC with li-po and have seen them catch on fire.

    But looking at the pictures I beleive it's printed on the battery case as li-Ion.

    Maybe a miss print in step 22? Maybe it should say Li-Ion?

    Don't get me wrong, it will be a great day when Li-Po is more stable for electronics.

    No, a VGA camera would have a lens assembly and a different looking sensor.

Or it is kind of a primitive solar cell which transfers the light to electric current detectable by the device.

    Resistors and diodes have two leads, but a lot of ambient light sensors have a built-in amplifier or analog-to-digital converter to make integration easier. For example, see the Toshiba TBS852. Even if the device doesn't have an amplifier, it's common on small packages to have extra leads whose only function is mechanical. But, since there is a capacitor next to this package, it probably has this extra circuitry.

    • 以下是重量分类:铝背:138克,电池:148克,LCD: 153克,玻璃(和框架):193克,扬声器:17克,主板:21克,其他所有:27克。

    • 总计:697克(比苹果报的0.68公斤略重,还有其他人称他们的iPad吗?)

    • 这可能是一部分,但我们将继续深入挖掘它的芯片。跟随@ifixit获取最新的更新!

    Wait, no moving parts? Can't wait to find out this thing's achilles heel.

    The moving parts are the various buttons and the no-tilt slide switch. The Achilles' heel will be the small amount of RAM and limited flash storage space. The 2nd gen will most likely address the latter (just by increasing it), and possibly the former.

    Do you have the weights for the component pieces in the step 31 photo? In particular how much does the aluminium back piece, the batteries and the screen each weigh compared to the total weight?

    I added the weights to the step. On my scale, the total weight of the iPad came out to 697 grams. That's definitely more than the .68 kg quoted in the Apple specs.

    Mine weighed 24.2 oz, which is 686 grams. Maybe the different display mfr causes a 10g difference.

    Any chance you guys did a wallpaper shot after removing the screen? Please tell me you did.

    Yes but if you go to http://www.apple.com/ipad/specs/ and go to footnote number 1 it reads, Actual size and weight vary by configuration and manufacturing process.

    Achilles' heel to me is like the DC cables on the first Aluminum iMac, or the bad capacitors in the iMac G5, or the top cases on plastic MacBooks, or the liquid cooling system on PowerMac G5s, or the DC-in boards on MacBook Unibody, or headphone jacks on iPod Video 5th gen, or yellow LCDs on the 27" iMac, etc. - not a lack of features.

    There always seems to be some problem that has to get fixed on hundreds of these things. As a repairman, this is where the opportunity is. I think it will be just the headphone jack and the glass/LCD but one can always hope...maybe the batteries will swell up if the cells drop below 3V?

    No moving parts, but what makes the clicking noise when you wake the ipad up or put it to sleep. Sounds like heads being parked, but that can't be the case with solid state drives.

    Sure enough! Weird that Apple chose such a sound to coincide with waking/sleeping.

    Quote from opie:

    I haven't heard it, but 'clicking sound on sleep/wake' sounds more like bad design of the audio DtoA & amp, so that glitching sounds during circuitry power on/off switching and software initialization make it through to the speakers.

    This is the sort of screwup you'd expect in a $20 MP3 player, not an Apple iWhatever.

    TerraHertz - 回复

    No, I'm pretty darn sure that the click is on purpose. Its there on every single iDevice. Have you ever used one? :)

    its a intentional feature apple put in the device, all iPhone os devices do it, its to let the user know that the device is off or on, people like that sort of confrimation

Is it possible to replace the A4 with a better processor or add RAM?

Todd Ransom - 回复

No, it is not possible. You cannot upgrade any parts on this, or later generation iPads, since the boards are all completely custom designed for each generation, and not compatible. Also as in most laptops, the size constraints mean that the processor was not intended to be replaceable, as is clear when you look at step 15.

can I change the logic board?

Yes, you can. The system memory will be entirely different, though. iPad Wi-Fi Logic Board Replacement
