The good folks at iFixit have managed to get their hands on a brand new, hot off the production line iPad 2. Let the teardown commence!

First off, a change that isn't for the better. The new tapered edge on the iPad 2 prevents any kind of tabs from being used as was the case with the iPad 1. Instead, Apple engineers have used enthusiastic amounts of adhesive to keep the front glass in place. A downside of this is that the front panel is very difficult to remove. In fact it's almost impossible to open the iPad 2 without shattering the glass. iFixit will be working hard in the forthcoming weeks to provide a solution to this problem, but for now the advice is simple - don't open your iPad 2!

Here are some teardown highlights:

  • iFixit 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.
  • Lifting off the LCD exposes the iPad 2's battery. iFixit discovered 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.
  • It has now been 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   - 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.

The iFixit team has given the iPad 2 a repairability score of 4 out of 10, mainly for the extreme difficulty of accessing anything inside. One inside the iPad 2 all screws are of the Phillips variety, and the LCD can be easily taken out once you separate it from the front panel glass.

Below is the main logic board:

  • Blue outline - Texas Instruments (TBD)
  • Yellow outline - Apple 343S0542
  • Green outline - S6T2MLC N33C50V Power Management IC
  • Red outline - Apple 1GHz A5 Processor
  • Orange outline - Toshiba TH58NVG7D2FLA89 16GB NAND Flash

    Hmm, interesting... thinner equals less durable. Go figure.

    • Yeah so lets make tablets thicker and heavier!

      @Peter Perry
      That's the ticket? Or is it?

        @James Quinn I would say it is and the thing that would concern me is how easy the iPhone 4 screens were cracking when they got the slightest scratch as this could happen with this device as well.<br><br>Also, I was playing with one in the Apple store, both the original ipad and the Xoom feel much more solid to the touch. <br><br> oh and coicidentally, when I was buying my invisishield somebody walked up with the latest iPod touch asking if they could repair his cracked screen but the rest of the device looked sound and undamaged.

        <i>Also, I was playing with one in the Apple store, both the original ipad and the Xoom feel much more solid to the touch</i>

        I have used a few pc notebooks, which are both thicker and heavier than my MacBook Pro. Being thicker and heavier does not equate to feeling much more solid. It certainly does equate to being more cumbersome though.

        @James Quinn
        your hand. First of all besides you and a few other well known and established Apple haters I've not read anything about the iPhone 4 terrible screen issues. I would tend to doubt that after having such problems (imaginary on your part perhaps?) that Apple would repeat said problems with a larger screen size or another product. Apple is not perfect but Apple does tend to learn from mistakes and like I said I've not read here or in any major news outlet that I look at any such news and yes that would be news. Also you are a well known Apple haters and I'm suppose to believe that you spend your time using such devices and in Apple stores? You are such an odd duck or making things up? Can't tell which but it's one or the other.

        @James Quinn <br>i4 glass issues?<br>Jim you need to catch up.<br>Insurance numbers (I can look up one of the links but you can google it or search in ZDNet) show that there has been significant increase in glass breakage on the i4. <br><img border="0" src="http://www.cnet.com/i/mb/emoticons/wink.gif" alt="wink">

        @James Quinn I learned a bit ago that youre clueless... I have seen the cracked glass myself on the back of a friends iPhone 4 at work.<br><br>Just because you don't want something to be true doesn't mean it isn't.<br><br> oh and I still have a 32 gig I pad here, so don't give me your shit. If you want I can take a picture of it beside the xoom.

        Notice how many 'coincidences' there are in Peter's stories? Reminds me so much of NonZealot's tall tales. Wonder why?

      • It's Glassgate!!! :P

        @James Quinn .....poor Steve! ...Can't get any rest from Antennagate to Glassgate. But hey..... lying and using his RDF radiation, coupled with cheap parts to gain market share isn't exactly kosher, even as a Gypsy Barker in a Circus!

      • Lets see have seen cracked glass yourself?

        @Peter Perry
        Yeah and I can verify this how? You can take a picture of your Xoom and iPad. Well either one of two cases here. You are not a very good consumer. Purchasing from a company you clearly dislike even hate and a product you should have known did not meet your needs? HUH!?! Or you can borough an iPad from someone you know who has one (since plenty have sold out there ) and tell me it's yours? Which is it? 6000 Google posts about iPhone 4 glass issues? Oh thats reliable. How says anything on the web is fact based? If I were a major competitor of Apple's or an Apple hater I'd post such stories and pay to have it done if I had the money available to do so. Please give me a real researched story from a reliable none biased news source and then we'll talk.

    • Deju Vu Rubber Bumpers!

      @Peter Perry No doubt they again used Chinese fake Corning Gorilla Glass that is only made in Georgia and their new factory in Japan. Just because it's chemically hardened doesn't make it really durable. It's the process that Corning has patented, not the chemicals used. But..... really amazing that Apple failed to learn from dropped signals to not be so focused on fadish looks of innovation to end up covering it up with an ugly rubber bumper. Now here they are doing it again.

      I was wondering why they are making such a big deal over the Magical and Revolutionary "Smart Cover" (not so smart if the device requires it to stay in one piece)!!!

      New..... Improved iPad 2 (don't look at it WRONG or it'll break)!!!

      • Ah the issue that wasn't:)

        @Monarky
        Now let me see. Apple's iPhone can't hold a signal nor can it remain undamaged from the slightest little thing or impact? Yet even today the iPhone 4 sells quite well indeed. Now I know you are going to use the "Apple is purchased by sheep" or "People who buy Apple want to be cool" excuses to justify the contrast here. You might even try the often used "Marketing" justification/Rational. Yet I'm going for this one.... Consumers purchase what they like/need. So the iPhone 4 meets there needs and wants. Since I would think many a consumer wants/needs a device that does not break at the slightest scratch or actually functions as it should your "issues" are well not issues at all and just made up on your part:)

      • Yes... Sheeple are people too...

        @Monarky .... yes, those that wear blinders and are unable to see the ultimate motivation behind Apple's Greed and malfeasant business practices are doomed to get burnt in the end. Just as we now see has also happened to another American Corporate Giant..... GMC. Who'd have thought that the largest Automobile manufacturer in the World would ever go under? But they did by resting on their laurels, in going to hell in a hand basket. If this can happen to them.... then it is indeed possible for it happen to Apple.

        No doubt Apple has brought some great innovative products to market in their history. Just like GM had. But these two giants stopped putting their customers first, believing their BRAND was their best selling point. So they instead went for budgeting their products parts for highest profits and this in the end is what killed them and their Brand!

        With both Original iPod and iPhone they did not do insert cheap budget parts. It was something we assumed only Microsoft would do with Zune and Xbox 360. Only they would be too cheap to make it right the first time... right? They use New, Improved and First Marketing ploys to sell us inferior products. With Xbox 360 it's worked Branding worked to overcome boneheaded cheap parts moves, just like it's worked for iPhone4 and iPad. But how long will it work and will it on their next product? You can fool the public some of the time and most of the fans near all the time once.... but history says even the fans get tired of being duped a 2nd time!

        No product should ever be built solely to meet a budget or just looks. Apple has gotten sloppy in their design methodology, when for almost 20years you could expect that a Mac or any Apple product was first of all, not only designed in America, but built in America where they used first class American labor and parts.

        Now Apple doesn't even use first grade Chinese parts, because assume their Brand recognition will sell their products alone. It will.... to a point, but that point is rapidly coming to a close. Again.... Consumer Reports says they can not recommend iPhone4 because of design and parts deficiencies.

        Although the processor has been designed and built in conjunction w/ one of the premier chip foundries in the World (Samsung's), it's firmware is lacking ARM's own coded feature set support. Though they do take advantage of Samsung's best practices manufacturing processes, they fail to fully take advantage of the power of these new dual core chips, in conjunction w/ other cheaper parts in their devices now. This has all been well documented in these tear downs and is reflected by what Apple pays for parts cost to meet a given budget (always cheaper compared to competitors). We no longer find all the best parts in Apple's products like we once did and that is the first sign of a company in decline. Focused too heavily on profits over ultimate customer satisfaction that in the end will come back to haunt them.

        Maybe not today.... or even this year or the next, but eventually putting profits over true innovation and resting on your laurels always comes back to bite us all in the end! Apple is proving they are a company headed in that direction!!!
