Apple’s iPad 2 Smart Cover Teardown Uncovers 21 Magnets

Written by Gradly on . Posted in Apple, blog, iPad, News, Reviews, Tech.

A total of 31 magnets are used to make the iPad 2 and its Apple-branded Smart Cover properly align, with 21 magnets found in the accessory and the remaining 10 in the iPad 2 itself.

After they teared down the iPad 2 the team iFixit for the first time ever,  conducted a teardown of a case, a move that highlights the unique nature of Apple’s Smart Cover for the iPad 2. When the iPad 2 was first introduced, Apple touted that its accessory cover was developed alongside the new touchscreen tablet.

The solutions provider utilized magnetic viewing film to demonstrate the magnetic poles of the material inside the Smart Cover. It found that one magnet is used to turn off the iPad 2 screen, while the rest are used to either clamp the case to the iPad 2 or form the triangle shape that allows the case to act as a stand.

The sleep control for the iPad 2 can even be triggered with a separate magnet without using the Smart Cover, automatically enabling or disabling the screen.

Inside the iPad 2, a row of magnets are located on the right side of the device, making the Smart Cover clamp to the surface of the device. The magnets are clearly labeled with their alternating polarity, which ensures the Smart Cover always sits in the same orientation.

Also included in the iPad 2 are a row of magnets along the left side of the device, which allows the Smart Cover to latch onto the side and pivot to open and allow access to the screen. iFixit found that the magnets inside the iPad and its accompanying Smart Case on the left side are “very strong,” and witnessed them make a two-inch leap to connect.

Inside the Smart Cover, iFixit found:

  • A large metal place encased in plastic that adheres to the magnets to form the stand.
  • Two yellow all-plastic plates in the middle that exist purely for structural support.
  • A stack of magnets.

The teardown also revealed that Apple opted for a steel-to-magnet bond, which is weaker than a magnet-to-magnet bond, which is why there are a total of 21 magnets inside the case. iFixit said that Apple needed “lots more magnets to prevent the case from literally falling apart during use.”

The Smart Case does not use any correlated magnets, which have a complex field of patterns rather than standard positive and negative polarity. The magnets used by Apple inside both the Smart Cover and iPad 2 are regular two-pole magnets.

Last week, iFixit conducted a more traditional teardown of the iPad 2 itself. The disassembly of Apple’s latest touchscreen tablet revealed that the new device has a slightly bigger battery than its first-generation counterpart, as well as double the RAM with 512MB.

iPad 2 Teardown: Glass is 27 Percent Thinner

iFixit has posted a detail teardown of the just released iPad 2, revealing a great deal about the inner working of the latest creation from Apple. The iPad 2′s glass is significantly thinner than the previous iPad. More from iFixit:

  • 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
    • 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!

First iPad 2 Reviews Go Live: Evolutionary, 512MB RAM, Thinner, Faster

Apple’s iPad 2 launches this Friday, but the first reviews are starting to trickle in. Apple typically supplies pre-release hardware to certain organizations for early review. Here are the early reviews, with a summary of what they had to say:

Mossberg – The Wall Street Journal

As new contenders move into the field, Apple isn’t likely to keep its 90% share of the booming tablet market. But the iPad 2 moves the goal posts, by being slimmer and lighter, boosting speed and power, and holding its price advantages, available apps and battery life. As of now, I can comfortably recommend it as the best tablet for average consumers.

Joshua Topolsky – Engadget

It might frustrate the competition to hear this, but it needs to be said: the iPad 2 isn’t just the best tablet on the market, it feels like the only tablet on the market. As much as we’d like to say that something like the Xoom has threatened Apple’s presence in this space, it’s difficult (if not impossible) to do that. Is the iPad 2 a perfect product? Absolutely not. The cameras are severely lacking, the screen — while extremely high quality — is touting last year’s spec, and its operating system still has significant annoyances, like the aggravating pop-up notifications. At a price point of $499, and lots of options after that (like more storage and models that work on both Verizon’s and AT&T’s 3G networks), there’s little to argue about in the way of price, and in terms of usability, apps like GarageBand prove that we haven’t even scratched the surface of what the iPad can do.

For owners of the previous generation, we don’t think Apple’s put a fire under you to upgrade. Unless you absolutely need cameras on your tablet, you’ve still got a solid piece of gear that reaps plenty of the benefits of the latest OS and apps. For those of you who haven’t yet made the leap, feel free to take a deep breath and dive in — the iPad 2 is as good as it gets right now. And it’s really quite good.

MG Siegler – TechCrunch

In January 2010, shortly after its unveiling, I first got my hands on an iPad. My initial reaction? “The iPad is like holding the future.” And that’s funny because here we are, just a little over a year into that future, and something new has come along that makes holding the iPad 1 feel like holding the past: the iPad 2.

A week ago, after its unveiling, I got some hands on time with the new hardware and my initial assessment was that it pushed a device that already had no true competition even farther ahead. But now I’ve had the chance to actually use the thing non-stop for a week. Is my feeling the same?

Actually, it’s even stronger.

The original iPad was considered a huge hit — but that was with no real competition. The iPad 2 has some competition — right now, the Xoom, and many more are coming. But I have no doubt that the iPad 2 will be an even bigger hit than the original.

Jason Snell – Macworld

For Apple’s competitors in the tablet-device market, the iPad 2 is a bucket of water to the face. After more than a year of struggling to catch up to the original iPad, here’s a new model that addresses many of the iPad’s deficiencies, dramatically improves its speed, and doesn’t cede any ground on price, features, or battery life. The iPad 2 raises the bar Apple set a year ago—and it’s time for the rest of the industry to scramble again to catch up.

… the iPad 2 is a triumph, an iPad that’s even more iPad than the original. And the original one was really good. The first iPad was a bolt from the blue, a device that defined an entire category, and a tough act to follow. The iPad 2 follows it with aplomb.

Apple has posted 14 guided tour videos showcasing the iPad 2 and the new apps including Garageband and iMovie.
