IPAD Tear down

미FCC 가 일부 공개했으며 ifixit에서도 공개한 사진들 올립니다.

One word of caution: This is likely a preproduction board, and Apple very well may have changed some suppliers since they gave the FCC a sample unit. Take this data with a grain of salt until we are able to analyze a production model tomorrow.

It looks like there is a LOT of epoxy holding these chips down to the board. More than we've seen before— Apple is really serious about durability on this thing.

Apple A4

Broadcom BCM5973

Bottom of logic board, with and without the EMI shield.

We're very happy to report that Apple didn't solder the battery! The iPad uses the same battery attachment system as the iPhone 3G and 3GS.

It looks like this board was made by AT&S. It will be interesting to see if their marking remains in the final production board. We haven't seen Apple's PCB manufacturers brand their boards before.

3.

This cable carries the signal from the dock connector to the logic board.

Never one to waste space, Apple also managed to tack the wifi and bluetooth boards onto this cable.

Like some other Apple devices we've seen, the home button is low-tech. There's two contact points that mate with pads on the display assembly. When the button is pressed, the circuit is completed.

Notably lacking from this RF/data cable is anything GPS related.

4.

Wi-fi and Bluetooth are integrated into a single board. Broadcom has been one of Apple's favorite suppliers recently. It's possible this is the same BCM4329 chip that Apple used in the 3rd Gen Touch.

Laser engraved on the cover:

• X17B ES2.0-A4
• APN 339S0107
• USI 20091207

The bracket shown in the second picture is both a cable clip and a ground point for the WiFi/Bluetooth/cable assembly.

5.

A shot of the speaker assembly.

The dual speakers provide stereo sound. Two small sealed channels direct sound toward three audio ports carved into the bottom edge of the iPad.

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.

6.

The inner side of the display assembly.

The part number is hard to make out, but it looks to be LP097X02. If that's correct, then the display is made by LG-Phillips.

This is very likely the most expensive part of the iPad. It uses expensive IPS (in-plane switching) technology and is LED backlit (as opposed to the cheaper TN and CCFL backlit).

Display LED barcodes: 1579CN7346569 3225 LG0NJ 'GK65284221MTA', and 5091L-0942B 091214 R51 K319CED5D61R0094B2

The battery is quite obvious to pick out of this picture of the rear case (sans display assembly).

The 3.75V, 24.8 watt-hour (6.5 Amp hour [!]) battery provides the juice for an advertised 10 hours of use. In contrast, the iPhone 3GS has a 4.51 watt-hour battery and the MacBook Air has a 40 watt-hour battery.

The battery seems to integrate two separate 3.75V lithium polymer cells wired in parallel for such ample battery life.

The USB power supply had to be enhanced specifically for the iPad. It's a 10W unit manufactured by Foxlink Technology, Ltd., part #A1357 W010A051.

1. 우리가 분해한 제품은 정식 출하(4월 3일)하기 이전의 제품이다. 따라서 양산되는 제품에는 차이가 있을 수 있음을 감안해달라. 애플은 주로 삼성과 도시바의 낸드플래시를 납품받아 사용하는데, 우리가 분해한 제품은 도시바의 낸드플래시가 탑재되어있었다.

2. 칩들을 고정시키는데 평소보다 많은 양의 접착제가 사용되었다. 이 말인 즉슨, 랩탑보다 내구성이 더 단단할 것이라는 뜻이다.

3. 배터리가 메인보드와 결합되어있는 형태가 아니다. 즉, 배터리를 교체하는 것이 그리 어렵지 않다는 뜻이다. 물론 애플은 배터리교체를 신청하면 아이패드 전체를 교체해주지만...

4. 메인보드는 AT&S에서 제작되었다.

5. 공간절약을 위해 무선랜과 블루투스 보드가 30핀 커넥터와 메인보드를 접속시켜주는 케이블에 연결되어있다. 이렇게 함으로써 추후 이 부분을 업데이트하는 것이 더 용이할 것이다. GPS는 이 케이블에 연결되어있지 않다.

6. 무선랜과 블루투스 보드는 애플이 3세대 아이팟 터치에 사용한 것과 같은 칩셋인 BCM4329이다. 제품코드 X17B ES2.0-A4, APN 339S0107,USI 20091207 라고 커버에 인쇄되어있다.

7. LCD는 LG Phillips사의 LP497X82 모델이 탑재되어 있었다.

8. 배터리가 24.8WH나 된다. 이는 거의 맥북에어(40WH)에 근접한 사양이다. 아이팟 터치는 4WH에 불과하다. 두 개의 3.75V 리튬폴리머 셀 배터리가 병렬로 연결되어있다.

9. USB 전원 어댑터는 아이패드 전용으로 특별히 설계되었다. Foxlink Technology에서 제조되었으며 10W의 용량을 가진다. 파트번호는 #A1357 W010A051.

10. 아이맥처럼 뒷면의 사과마크를 통해 무선랜 안테나가 신호를 받는다. 나머지 다른 면들은 통알루미늄이다. 두번째 안테나는 앞면의 좌측하단에 유리배젤 안쪽에 자리잡고 있다. (무선랜 강도를 유지하기 위해 두개의 안테나를 채용한 듯.)
