Step 2

• Contents of the box:

  • iPad
  • Dock Connector to USB Cable
  • 10W USB Power Adapter
  • Documentation

• Before we proceed with our iPad teardown, a quick announcement: On April 22, 2010, iFixit will change repair forever.

Step 4  跟其他产品对比

• The iPad measures in at 242.8 x 189.7 x 13.4 mm and weighs in at 1.5 lbs.
• The significantly improved 9.7 inch LED-backlit glossy widescreen with Multi-touch is perfect for all your movie watching, e-book reading needs.
• The iPad's model number is A1219, which doesn't mean much. But the 3G iPad is A1337, which is rather geeky, even for Apple.
• Yes, we did turn it on—how could we not? But then we turned it right back off and started figuring out how to pry this beautiful machine apart.

Step 5 免螺丝设计，其实就是跟iPhone一样的粘接。

• iPad, meet iPod original.

  • More like: Flying saucer, meet horse & buggy.
• The iPad stacked upon a MacBook Pro, stacked upon a Dell laptop.

Step 6 环保产品

• Insert a metal spudger between the display and the rear case to pry the iPad open.
• What an environmentally friendly device!

  • Arsenic-free display glass
  • BFR-free
  • Mercury-free LCD display
  • PVC-free
  • Recyclable aluminum and glass enclosure
• Environment WIN!

Step 7  占据了主要空间的大块头电池

• Lift the display assembly away from the rear case.
• A first peek under the hood reveals two huge Li-ion Polymer batteries taking up most of the space in this device.

Step 8

• Aaaand it's off. You have no idea how glad we are that this didn't require a heat gun.
• Words from the wise: You might break some tabs getting the display assembly off.

Step 18

• Removing the single screw securing the dock connector cable to the rear case.
• Notably lacking from this RF/data cable is anything GPS related. Check out the FCC iPad teardown to see where the GPS will be in the 3G device.

Step 19 Broadcom的无线模组

• The 802.11n WiFi/Bluetooth card is integrated into the dock connector cable.
• Hiding under the case:

  • Broadcom BCM4329XKUBG 802.11n WiFi + Bluetooth 2.1 + EDR and FM
• Dont worry, the capacitor near the lower right corner of the Broadcom chip didn't come that way. The solder melted and it moved when we heated the steel casing to remove it.

Step 20 双喇叭单声道，但外接音响是立体声

• The speaker assembly is larger than we expected:

  • 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.
• Dual speakers provide mono sound. Two small sealed channels direct sound toward three audio ports carved into the bottom edge of the iPad. The audio-out jack provides stereo sound, of course.

Step 21

• That's a hulk of a battery: it weighs 148g with the casing.
• Confirming our suspicions from yesterday, the battery integrates two separate 3.75V lithium polymer cells wired in parallel for such ample battery life.
• Battery cell markings:

  • P11GA6-01-C01F
  • 741-00310A +

Step 22 每个电池组都有独立的保护板，并非常见的2并管理，

• The iPad battery is a lot bigger than an iPhone 3G battery. The iPhone battery has about 1/5th the capacity provided by the iPad battery.
• The second shot shows the battery cover peeled back to expose the protection and connection circuitry for each Li-Poly battery.
• The third shot shows the other side of the battery board, which is stamped with Compeq.

Step 23 巧妙的天线设计

• The bare rear case. The antenna behind the apple logo looks just like the antenna on the new iMacs.
• A little prying with a metal spudger is required to separate the antenna from the rear case.
• Tolerances look pretty tight in the antenna compartment. Check out that pocket just for the antenna to sit in.

Step 24 添加3G模块，并不容易

• Here's a detail shot of both WiFi antennas. The wireless reception should be decent with such dense antennas.
• Adding 3G capability to a Wi-Fi only iPad is not going to be a very feasible upgrade. Based on the photos released by the FCC, the 3G models include additional antennas as well as a plastic strip in the rear panel to improve reception.

Step 26 home键是数字开关

• Ants on parade? Nope, just the T4 Torx screws holding each tab to the display assembly.

  • Each clip holding the display assembly to the rear case is fastened down with its own T4 Torx screw.
• Luckily, the home button is a digital switch with its own circuit board, making replacement that much easier.

Step 27 LED背光连接

• Disassembling the display assembly.
• A thin ribbon cable connects the LED driver board to the LED backlights.
• The LED driver circuitry and the interconnects between the actual LCD and the display data cable connector are contained within the same circuit board.

Step 28 不是摄像头，是环境光传感器

• The ambient light sensor lives in a compartment that a camera would love to call home.
• We suspect that this compartment was intended for the ambient light sensor all along, and the rumors of a camera that would fit here were overzealous. The layout does look very similar to the camera's view ports on the MacBook Pro 13" Unibody.

Step 29 更厚的玻璃，LCD重153g,玻璃重193g

• The display seems to be glued around its perimeter but can still be removed from the plastic framework.
• The display assembly weighs in at:

  • 153g for the LCD
  • 193g for the front glass
• The glass seems quite thick (~1.18 mm), which is not a huge surprise considering the size of the iPad. Compare that to about 1.02 mm for the iPhone.

  • The iPad would require thicker glass due to the increased "lever arm" caused by pressing down at the center of the screen. This is analogous to the difficulty of bending a one inch section of a ruler compared to bending the entire twelve inch ruler.

Step 30

• Some front glass/digitizer part numbers.
• The part number on the display frame reads:

  • HIA097NRFE0XA
• On the digitizer cable:

  • 821-0757-A
