iSuppli在对黑莓Torch拆解后发现，该手机采用的元件来自Synaptics、Marvell、三星、英飞凌、瑞萨和德州仪器等公司。其中最昂贵的元件为显示屏和触摸屏，总成本为34.85美元。其次为存储元件，成本也高达 $34.25。其它的部分分别是：音频系统成本 $23.35，应用处理器成本$15，天线/射频 $24.50，面板12.40美元，电池15.90美元，摄像头10.80 美元。

iSuppli分析师安德鲁· 拉斯维勒(Andrew Rassweiler)表示，从内部来看，黑莓Torch 9800与RIM近期推出的其他智能手机类似，采用的主芯片来自 Marvell，成本为15美元。RIM此前在黑莓Bold 9700中也使用了类似的Marvell芯片。黑莓Torch 9800的触摸界面技术则采用了新思科技（Synaptics）的芯片。此前黑莓Storm 2和谷歌Nexus One也采用了这一芯片。

在iSuppli的拆解过程中发现GPS新芯片——新的GPS集成电路，产自英国CSR PLC公司。如果除掉制造成本12美元，Torch的原材料和组件成本为171.05美元，而iPhone 4总成本为187.51美元。在整机中成本最高的是LCD触摸屏，价格为34.95美元，占总成本的20%。在iPhone 4中显示屏同样是最贵的部件。

分析师说，从零售调查来看，与竞争对手手机上市的情况对比，Torch在美国的上市初期销量没有给人留下太多印象。RIM拒绝对iSuppli的拆解报告置评。目前在与AT&T签订两年使用协议的情况下，黑莓Torch的售价为199美元。这款手机的裸机价为499美元。

BlackBerry Torch Carries $171.05 Bill of Materials, iSuppli Teardown Reveals 

August 17, 2010 

Andrew Rassweiler

Research in Motion Ltd.’s new Torch 9800 smart phone carries a Bill of Materials (BOM) of $171.05, according to a dissection and cost model conducted by the Teardown Analysis service at market research firm iSuppli Corp.

“On the outside, the Torch delivers a rich feature set, with three User Interfaces (UIs): a capacitive touch screen, an optical track pad and the first slider QWERTY keyboard found in a BlackBerry,” said Andrew Rassweiler, principal analyst, teardown services manager, for iSuppli. “On the inside, the Torch’s electronic design heavily leverages subsystems used in previous members of the BlackBerry smart phone line, specifically the Storm2 and the Bold 9700. With this evolutionary approach, RIM has delivered a smart phone with an enhanced feature set that largely matches those of the BlackBerry’s chief competitors: the iPhone and the Android-based handsets.”

Firsts and Seconds
Along with the QWERTY slider keyboard, the Torch delivers a number of other firsts for the BlackBerry line, including the newly rewritten BlackBerry OS 6, as well as Social Feeds, Universal Search and a faster WebKit-based browser. The new BlackBerry smart phone also contains a GPS Integrated Circuit (IC) from CSR plc, the first time iSuppli has seen this new chip in a product teardown.

On the other hand, the Torch’s Radio Frequency (RF), power amplifier and power management subsystems are similar or virtually identical to those of a previous member of the BlackBerry line, the Bold 9700, which had been torn down in the past by iSuppli. In terms of specs and size, the Torch’s display is very similar to that of the BlackBerry Storm2 9550. Furthermore, the Torch employs the same Microelectromechanical Systems (MEMS) accelerometer by Analog Devices Inc. used in the Storm2 9550.

The Torch also bears some similarity to smart phones from other brands. Mechanically, it is comparable in complexity and cost to HTC Tilt 2. Likewise, the Torch integrates Texas Instruments Inc.’s WL1271x WLAN/BlueTooth IC, which can be found in products including Motorola Inc.’s Droid X and Microsoft Corp.’s Kin 2.

Torch BOM
When adding in an estimated manufacturing cost of $12, the Torch’s combined production and BOM cost amounts to $183.05.

Cost Countdown
The most expensive subsystem in the Torch is the LCD and touch screen display module section, at a price of $34.85, representing 20.4 percent of the product’s BOM, according to iSuppli’s semiconductor costing estimate. The display is a 3.2-inch diagonal TFT LCD with a 480 by 360 pixel resolution. While it was not possible to identify from a teardown analysis the supplier of the display, RIM in the past has employed displays from Samsung Mobile Display, Toshiba Mobile Display Co. Ltd. and Sharp, according to mobile market research from Vinita Jakhanwal, principal analyst, small/medium displays for iSuppli. The touch screen uses capacitive technology and includes a Synaptics Inc. controller IC. And although the supplier of an entire module is rarely identifiable from a teardown analysis, the controller IC indicates that Synaptics is a potential supplier of the turnkey solution.

Coming in at a close second in terms of cost is the memory subsystem, at $34.25, amounting to 20 percent of the Bill of Materials. In the individual Torch torn down by iSuppli, Samsung supplied a 4Gbyte eMMC NAND flash memory device, plus an 8Gbit NAND flash and 4Gbit Mobile Double Data Rate (DDR) SDRAM

SanDisk Corp. contributed a 4Gbyte removable Micro SD memory card.

The mechanical/electromechanical portions of the Torch, including the printed circuit boards and the enclosure plastics and metals, came in third at an estimated cost of $23.35, representing 13.7 percent of the Torch’s BOM.

Marvell, Infineon, Renesas Light up the Torch
Next on the cost ranking is the applications processor/baseband section at $15, or 8.8 percent of the BOM.

This section is dominated by the communications processor, which features an integrated baseband from Marvell Technology Group Ltd.

Coming in at fifth in terms of cost is the RF transceiver and power amplifier section, at $13.90, or 8.1 percent of the BOM cost. Infineon Technologies AG’s PMB5701 tri-band RF transceiver is featured in the section, along with Renesas Electronics Corp.’s R2A60177BG quad-band RF transceiver and its RPF59001B power amplifier module.

User Interface Chips
The user interface electronics subsection comes in sixth, at $12.40, or 7.2 percent of the BOM. This section includes STMicroelectronics NV’s STV0987 video/image processor that supports mobile imaging. It also features Texas Instruments Inc.’s TLV320AIC36IZQERaudio codec, CrucialTec Co. Ltd.’s optical trackpad assembly and the Analog Devices 3-axis accelerometer.

Other notable sections include the Bluetooth/WLAN/GPS area, with a price of $10.60 and 6.2 percent share of the Bill of Materials. Components in this subsystem include the Texas Instruments WL1271A single-chip Bluetooth/WLAN/FM transmitter/receiver and the CSR GSD4t-9800 GPS receiver.

Finally, there’s the power management section, at $4.90, or 2.9 percent of the BOM. This subsystem includes the Texas Instruments TPS65856 power management IC.
