Step 1 Nokia N8 Teardown（一、诺基亚N8拆解）Our latest victim - Nokias just-released N8.（我们最新的牺牲品诺基亚最新发布的N8）Technical specs:（规格）*ARM11 680 MHz processor（CPU ARM11 680 MHz）*640 360 (nHD), 3.5 capacitive, multi-touch display with AMOLED technology （640360(nHD)分辨率，3.5寸电容屏，AMOLED技术，支持多点触控）*256 MB SDRAM（256MB 动态存储(内存)）color=*手机之家bbs.*512 MB internal NAND memory and 16 GB on-board memory （512MB 闪存和16GB 机身存储）*12 Megapixels (main) with Carl Zeiss optics and Xenon flash, 16:9 720p video, 25 FPS（主摄像头为1200万像素卡尔蔡司光学镜头，氙气闪光灯，16:9 720P，25FPS视频录制。） Step 2 * The 12 MP auto-focus camera is a honker. As weve seen in other smartphones, the thickness of the camera drives the thickness of the phone.（1200万像素的自动对焦照相机很骇人。对照我们曾经拆解过的其它智能机，N8的摄像头驱动器是最厚的。）* According to Dr. Hubert Nasse, the lens inside the camera module is composed of five individual aspherical shaped optical elements. This complex shape facilitates very high quality pictures out of a very small device.（根据Dr. Hubert Nasse的说法，这个照相机模块中的镜头由五个单独的非球面光学部件组成，这样的组合部件可以通过很小的部件得到非常高质量的图片。）color=*手机之家bbs.* Nokia chose to have the camera protrude outside of the back cover, which could either provide a good grasping point when taking the phone out of your pocket, or make it a hassle when returning the phone to your pocket.（诺基亚选择镜头突出后盖的设计，这种设计可以在手机从口袋取出时有一个很好的抓紧位置，但是放回口袋还是有点麻烦。？） Step 3 * Aside from a standard 3.5mm stereo headphone jack, the N8 features both a mini HDMI and a micro USB port. Not sure what to do with that HDMI port? Try setting a world record.（在标准的3.5mm立体声耳机插孔旁边，N8特别设置了mini HDMI和micro USB接口。不能确定HDMI接口有什么功能？首次看到这种设置。？）* Buttons include: Power, Home, Hold, Camera, and Volume Switch.（按键包括：电影将、主屏幕键、锁屏键、拍照键和音量控制键。）* The SIM and MicroSD ports are mounted side by side on the exterior of the phone, allowing for hot-swapping of the MicroSD.（SIM卡和MicroSD插槽并列在手机侧边，MicroSD卡支持热插拔。） Step 4 * Utilizing the front facing camera, apps such as Fring or Skype enable users to video chat anywhere they like with mobile-to-mobile as well as mobile-to-desktop connections.（前置摄像头可用于Fring或者Skype等应用软件的视频通话，手机和手机或者手机和电脑进行视频通话均可以随时实现。） Step 5* Hey look at that - visible T4 Torx screws! We figured this was a good place to start to take it apart.（嗨，看那里可以看到T4梅花螺丝！我们发觉这是开始拆解的很好位置。）* A trifle later the bottom portion of the phone was off. If we only had one of these.（接下来取出手机底面面部分有点小麻烦。如果我们仅仅有一个？） Step 6 * After the bottom cover of the phone is removed, a small battery retaining bracket can be popped out of its socket.（取出手机的下盖之后，可以从里面取出一个很小的电池固定支架。）* After that, the hologram-equipped battery can be slid out of its cozy home.（然后，整个电池可以从里面滑出来。）color=*手机之家bbs.* Although it requires the removal of two odd-sized screws, the battery really isnt that hard to replace. Thumbs up for no soldering!（尽管需要取出两个非标准尺寸的螺丝，要更换电池并不是很难。好在没有焊接起来。） Step 7* The BL-4D 3.7 V, 1200 mAh Li-Ion battery is considered non-removable. Sure Nokia, sure.（BL-4D 3.7V，1200mAh Li-Ion电池是不可拆卸的。肯定是诺基亚的产品，确定.）* The hologram stuck under the batterys pull tab is most likely there to ensure youre getting an actual Nokia-approved battery and not some low quality clone.（电池上的激光全息贴纸确认电池是诺基亚认可的，而非低质量的仿制品。） Step 8* After popping off the protective cover, a T5 Torx screw near the mini HDMI port can be removed.（拨开保护盖，可以旋下mini HDMI口旁边的T5梅花螺丝。）* The top of the phone comes off next, exposing more Torx screws for us to remove.（接着取下手机的顶盖，可以看到更多需要拆卸的梅花螺丝。）Step 9* The front part of the phone opens up like a clam.（打开手机的顶盖之后，很像一个蛤。）color=*手机之家bbs.* The digitizer and display cables still attach the front panel to the rest of the phone, so be sure to lift the display assembly from its top edge if you decide to open your unit.（警告！上部分仍然通过数据传输线和显示屏排线和剩下的部分相连，因此，拆机的时候要特别小心的握住屏幕的上部分。） Step 10* Thankfully the glass is not fused to the face of the AMOLED display, so you dont have to replace both if just the glass breaks.（谢天谢地，表面的玻璃并不是和AMOLED屏熔合在一起，因此，如果玻璃破裂，你不需要两个部分都更换。）* The silk screen on the back of the display reads AMS347FF01-0（屏的背面印着：AMS347FF01-0）color=*手机之家bbs.* The silk screen also indicates the display was manufactured February 2, 2010. This thing has been around for quite some time.（上面印着的信息说明这个屏是2010年1月生产，有相当长时间了。）* The touch screen controller is a Synaptics T1201A. This is the same chip found in the Microsoft Kin Two and RIM Blackberry Torch.（触屏控制芯片是Ssynaptics T1201A。跟微软Kin Two和黑莓Torch是采用的同一款芯片。） Step 11* Heres a comparison of the N8s display with an LCD from the 4th generation iPod Touch. You can differentiate between LCD and AMOLED screens by noticing the slightly blue tint the AMOLED display gives off when a light is shone against it.（现在对比一下N8的显示屏和iPod Touch 4的LCD屏。你可以看到LCD屏和AMOLDE屏的差别，在光照下，AMOLED屏显示偏蓝色。） Step 12* A couple T6 Torx screws and the upper antenna hold the mid-plane to the inside of the N8.（有一对T6梅花螺丝和上方天线部分固定中间平面到N8的内部。）* Six pads akin to steel wool help ground the back of the AMOLED display to the mid-plane.（六个钢丝绒垫用于AMOLED屏背面的中心定位。） color=*手机之家bbs.* Nokia got pretty creative with their antenna placement, as this device is primarily encased in aluminum. The main antennas are located near the flat plastic plates on the top and bottom of the phone, as seen in the second and third pictures.（诺基亚的天线位置有很好的设计，这个位置主要用铝包住。主天线位于手机顶部塑料盖平面部分内，可以在第二张、第三张图片上看到。） Step 13* After removing the screws and popping off the antenna, the mid-plane can be removed from the N8.（旋下螺丝，取出天线部分之后，中间平面部分可以从N8分离。）* The design of the steel mid-plane is pretty genius. Nokia integrated a large EMI shield into the mid-plane to protect the main chips. In addition, thermal pads were placed on the inner face of the mid-plane to conduct heat away from the main chips.（不锈钢中间平面的设计非常优秀，诺基亚有一个完整的电磁防护中间平面保护主要的芯片组。另外，这种设计便于主要芯片组的散热。）* As processor speeds increase and devices become more integrated, the need for thermal management becomes critical to ensure longevity and operability in many environments.（随着处理器速度的提示，内部结构更加整体化，为了延长使用寿命、适应不同的环境，需要很好的散热处理。） Step 14* After the mid-plane is removed, the motherboard can be simply lifted out of the rear case.（中间部分取出之后，主电路板可以很容易的取出。） color=*手机之家bbs.* The daughter board at the top of the motherboard has an interesting design in that it is connected to the main motherboard via a ribbon cable that is sandwiched between the many layers of the motherboard.（位于主电路板上方的子电路板有一个很有趣的设计，它们通过排线相连，组成三明治的形状。o On most devices, ribbon cables are attached with ZIF connectors or are soldered to the surface of the board, not sandwiched between layers.（在大部分的手机上，ZIF连接线是焊接在主板表面的，而不是类似这样三明治层的结构。） Step 15* The Nokia N8 motherboard: （诺基亚N8的主板）o Toshiba THGBM1G7D4FBA13 K23538 (16 GB Internal Memory) o Samsung K5W4G2GACA - AL54 (CPU + DDR RAM + NAND ROM)o Broadcom BCM2727 GPU with dedicated 3D Graphicso 4380044 9920Q VJ (RF Transceiver) from STMicroelectronicso EPCOS D1053 (RF Front end module)o RENESAS 09801A (RF Power amplifier)o 4376057 GAZ0035G (Baseband) from Texas Instruments Step 16 color=*手机之家bbs.* With the motherboard out of the rear case, the flash unit simply lifts out.（取出主板之后的剩下部分，可以取出闪光灯部件。）* As opposed to many other smartphones that use either a single or double LED for the flash, the N8 uses a Xenon flash tube similar to the kind of flash found in full-size cameras.（大部分的其它智能手机，都是使用的一个或者两个LED闪光灯，N8是采用的一个类似大部分数码相机上使用的氙气闪光灯。）* The large capacitor on the flash module supplies the high voltage necessary to produce such a brilliant flash.（闪光灯组件上的巨大电容能提供产生强闪光灯必须的很高的电压。） Step 17* The loudspeaker can be pried off the adhesive securing it to the rear case at this point.（喇叭是采用粘合固定。） color=*手机之家bbs.*o This loudspeaker is primarily used for speaker phone as well
