If you have questions or need assistance, were here to help. Go to www.motorola.com/consumer/support, where you can select from a number of customer care options. You can also contact the Motorola Customer Support Center at 1-800-331-6456 (United States), 1-888-390-6456 (TTY/TDD United States for hearing impaired), or 1-800-461-4575 (Canada).

Specific Absorption Rate Data

SAR Data

This model wireless phone meets the governments requirements for exposure to radio waves.
Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government and by the Canadian regulatory authorities. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age or health. The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC and by the Canadian regulatory authorities is 1.6 W/kg.1 Tests for SAR are conducted using standard operating positions accepted by the FCC and by Industry Canada with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR
level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station, the lower the power output. Before a phone model is available for sale to the public in the U.S. and Canada, it must be tested and certified to the FCC and Industry Canada that it does not exceed the limit established by each government for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) reported to the FCC and available for review by Industry Canada. The highest SAR value for this model phone when tested for use at the ear is 0.79 W/kg, and when worn on the body, as described in this user guide, is 1.4 W/kg. (Body-worn measurements differ among phone models, depending upon available accessories and regulatory requirements).2 While there may be differences between the SAR levels of various phones and at various positions, they all meet the governmental requirements for safe exposure. Please note that improvements to this product model could cause differences in the SAR value for later products; in all cases, products are designed to be within the guidelines.

Caution About High Volume Usage
Listening at full volume to music or voice through a headset may damage your hearing.

Glass Parts

Some parts of your mobile device may be made of glass. This glass could break if the product is dropped on a hard surface or receives a substantial impact. If glass breaks, do not touch or attempt to remove. Stop using your mobile device until the glass is replaced by a qualified service center.

Repetitive Motion

When you repetitively perform actions such as pressing keys or entering finger-written characters, you may experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of
your body. If you continue to have discomfort during or after such use, stop use and see a physician.

Objective:
To document internal components and PCB layout for Motorola W178g cellular telephone handset.

Summary:

A Motorola W178g cellular telephone handset produced for TrackFone Wireless Inc. provider was procured from a commercial source and disassembled to evaluate source of components and layout of the printed circuit board (PCB.) Enclosed with the handset was a Subscriber Identity Module Card (SIM card.) The card was de-processed to ascertain structure, design, technology node, and layout of thin films forming the semiconductor device die within. A separate report was generated to describe technology node and manufacturing processes used to build the SIM card integrated circuits. That study required a multi-step chip de-cap process and documentation of layout of the circuitry with optical (OM) and electron microscopy techniques (SEM, FIB and TEM.)

2008-3959 Page 5 of 15

Outline of Approach:
Document serial number identification codes and labels on packaging, handset and SIM card. Disassemble the handset into primary components and document layout Disassemble SIM card preserving semiconductor die within. Document layout of the die using OM and SEM Identify major components such as: bond pads, SRAM array, FLASH array, microprocessor, etc. Obtain cross-section (mechanical polish with FIB cleanup) through the center portion of the FLASH memory array using Optical Microscopy, SEM Obtain TEM cross-sections to identify film composition Identify elemental composition of thin films present on the device, discern inorganic from organic films SEM-EDS and TEM-EDS on the cross-section Compare contact pad structure to ascertain interconnect layers process flow and transistor design

Analysis of Devices:

Identification of part numbers:
Motorola W175g cellular handset was purchased at Target Inc. store in Redwood City, CA on November 10, 2008. The device was packaged for and marketed by TrackFone Wireless Inc. as a pay-as-you-go cellular telephone device. Photograph of packaging and the receipt for purchase of the handset is shown in Figure 1. The headset supports the following features: color screen, Crystal TalkTM voice enhancement technology, voicemail access, call waiting feature, caller ID, hands-free speaker, text messaging, vibration alert, an alarm clock, a phone book with up to 500 entries, and is preloaded with multiple ring tones.

The handset module was marked with manufacturer name and the model number as Motorola W175g and International Mobile Equipment Identity (IMEI) number: 011555006570360. Figure 3 illustrates the label attached to the telephone handset within the battery compartment. Handset was manufactured in China perhaps in work week 19 of 2008. This presumption is based on the notation (G 8/19) imprinted on the label.

Major components of the handset
Handset was disassembled by removal of screws securing together two sets of outside covers, unlocking tape seals, and removing keyboard and display panel from the main printed circuit board (PCB). The board was manufactured by Compeq Manufacturing of Taiwan using six-metal level process, as illustrated in Figure 6. Compeq Manufacturing operates assembly plants in China, Taiwan, and USA. The touch pad assembly also included display screen cover and speaker unit. The display unit was attached to PCB with flexible push in ribbon cable, the electrical switches for touch pad were permanently attached to back of the PCB and the components had imprint markings indicating assembly of that unit in work week 16 of 2008. Back of the PCB also had the microphone unit attached to it. The disassembled handset was photographed. Close-up images were taken of each semiconductor device attached to the PCB. Major components of the handset are illustrated in Figure 4 and Error! Reference source not found.

PCB layout and electronic devices:
The integrated circuit devices attached to the main circuit board were enclosed under metal heat-spreader/-sink soldered to the PCB. To uncover these components it was necessary to cut and remove the heat-sink. The LCD panel connector, headphone jack and microphone assembly were located outside of this heat sink. The components of the headset (see Table 1) followed reference design of a low-cost GSM/GPRS wireless headset platform designed by Texas Instruments: LoCosto Solutions: TCS2300GSM. A detailed description of features of this design is available at Texas Instruments Inc. website (http://focus.ti.com/docs/solution). The two largest devices visible in Figure 7 are the Texas Instruments DRP singlechip technology GSM/GPRS solution D65538UN7 and a power management solution T3031FZPH device. The handset also uses NOR-Flash FBGA memory module from Intel PN: 2030W0YUQE and SkyWorks SKY77517 dual band iPAC FEM for Dual-Band GSM/GPRS module. Based on documentation published by TI and available in the public domain, this is a basic mobile phone platform capable of delivering excellent voice quality at affordable price due to combination of RF transceiver, analog codec, and digital baseband into one highly integrated die produced at 90nm technology node.
