はじめにはじめに

Join us today as we disassemble Motorola's newest piece of gadgetry: the Atrix 4G.

Equipped with an Nvidia Tegra 2 housing a dual-core 1 GHz Cortex A9 processor and an 8-coreULP GPU, the Atrix 4G is set to dominate the world of mobile entertainment. Will the hardware of thismonster live up to the hype? Read on to find out.

手順手順 1 — Motorola Atrix 4G Teardown

Currently the most powerfulsmartphone on the market, the Atrixboasts some impressive technicalspecs:

1 GHz Cortex-A9 Dual-Core [!]Processor

8 core ULP (ultra-low power)GeForce GPU

4" qHD (Quarter High Definition)Display (960x540) protected by aGorilla Glass front panel

16 GB onboard memory, with upto 32 GB SD storage

1 GB DDR2 RAM

5 MP Rear-facing camera with720p video capture and VGAFront-facing camera

手順手順 2

Aside from a sleek carbon fiber finish, the back of the phone reminds you who made the phone,whose network you are calling on, and what quality video you can shoot.

Sorry to disappoint, but it is not actually carbon fiber. Instead it is plastic with a carbon fiberpattern. One of these days...

One of the most highly touted features of the Atrix is its connectivity. This is accomplished throughside-by-side micro USB and micro HDMI ports.

手順手順 3

The Atrix' back cover comes off easily, providing access to the user-serviceable battery and themicroSD card slot.

There's also instructions on the inside of the back cover showing how to remove the battery andreconnect the cover.

We applaud Motorola's drive to help its users with this procedure.




手順手順 4

We liked those directions, so we decided to follow them. Lo and behold, the battery came out veryeasily!

The 34.7 gram, 1930 mAh Li-Ion battery will provide up to 530 minutes of talk time on GSM, andup to 540 minutes on WCDMA.




手順手順 5

Exposing the innards of the phone proves to be a simple process. We are inhibited only by a fewT5 Torx screws and some plastic clips.

These are obstacles easily surmounted by iFixit's Home Tech Toolkit.

手順手順 6

An antenna is mounted in the rearhalf of the phone and must bedisconnected before furtherdisassembly.

A word on wireless connectivity:Although the phone is labeled 4G,the phone does not actually run on4G (hint: it still doesn't exist). Datatransfer occurs over HSPA+, aclassification of evolved 3G.

手順手順 7

This sticker comes off quite easily.Motorola used an adhesive thatwould allow the sticker to be re-sealed after being taken off. That'sgreat if you have to dig underneaththe sticker to fix something!

We haven't encountered any VOIDstickers or things of that sort whiletaking apart the Atrix, making itappear to be very repair-friendly.

手順手順 8

The LED flash unit is held in place by a set of small metal clips.

The LED flanks the 5 MP camera (which is capable of shooting 720p HD video). A softwareupdate to be released soon will reportedly allow for full 1080p video capture.

Disconnecting the last few cables allows us to remove the motherboard from its comfy home...




手順手順 9

Big players on the front of the boardinclude:

ST Ericsson CPCAP 2.2TC22 DCPower Management (thanks,Chipworks!)

Triquint TQM7M5013 LinearPower Amplifier

Qualcomm PM8028 RF PowerManagement IC

Toshiba eMMCTHGBM2G7D4FBAIE 16GBNAND Flash

Kionix KXTF9 MEMS MotionSensing Accelerometer

手順手順 10

The back of the board houses:

Qualcomm MDM6200 supportingHSPA+ speeds of up to 14.4Mbps

Hynix H8BCSOQG0MMR 2-chipmemory MCP

Elpida B8132B1PB. According toChipworks, the Elpida packagecontains 1 GB DDR2 RAM, butalso covers the Nvidia Tegra 2CPU/GPU residing underneaththe package.

Broadcom BCM4329 802.11n Wi-Fi, Bluetooth 2.1, and FM Tuner

手順手順 11

Next, the first of the two complex ribbon cables can be peeled off the steel mid-plane.

This cable houses the front camera, earpiece speaker, power button assembly, and topmicrophone. How's that for integration?

For enhanced security, the power button has a capacitive fingerprint scanner that can verify youridentity from a single swipe of a finger.

手順手順 12

We can also remove the rear camera assembly and its cable.

One cable to rule them all: the rear camera, proximity sensor, ambient light sensor, pressurecontacts for the headphone jack, and side volume buttons all come out as one piece.

What a decade can do for cables. Check out the thickness of a Parallel ATA cable compared to theAtrix camera cable. The PATA cable is 0.66 mm thick, while Atrix' camera cable measures 0.17mm! And they're routing several components through the same cable!




手順手順 13

To remove the metal plate behind the LCD, simply lift its top edge slightly while pushing it towardthe top of the phone.

After releasing it from its retaining clips, the LCD is readily accessible.




手順手順 14

And just like that, the LCD can be lifted from the glass front panel.

Huzzah! -- the LCD is not glued to the front panel glass!

The roughly 80% (this number is a rough estimate and is a calculation deemed accurate by theiFixit statistical department) of people who drop their Atrix now won't have to spend their moneyon replacing a fully functional LCD in addition to their broken glass!

The 960x480 qHD PenTile LCD is aptly named because it is the size of one quarter of a 1080ppanel.

The front panel houses an Atmel mXT224 touchscreen controller underneath the LCD connector.It's the same chip we've found on the Samsung Galaxy Tab, Nexus S, and HTC Evo 4G.

To reassemble your device, follow these instructions in reverse order.

手順手順 15

Motorola Atrix 4G Repairability Score: 9 out of 10 (10 is easiest to repair)

The LCD is separable from the glass front panel, making them independently replaceable.

The phone is held together with a limited number of screws and plastic clips. Adhesive isminimally used in its construction.

The battery can be removed in seconds.

No tools necessary for changing the SIM and microSD cards.

The phone feels solid in the hand, but the plastic rear panel is a little chintzy (that's right,chintzy).

The two main ribbon cables are soldered to many components (cameras, proximity sensors,etc.), making the cables costly to replace.
