V GND signal (Pin No: 3/9/11/20/21/31/36/46/49/52/61/63/78/80) is the power and signal ground of the module, which needs to be connected to the ground on the system board. If the GND signal is not connected completely, the performance of module will be affected. 2.4.2. DECREASE VOLTAGE DROP The power supply range of the module is 3.4V~ 4.2V. Because of the voltage drop during the transmitting time, a bypass capacitor of about 100 F with low ESR should be used. Multi -layer ceramic chip (MLCC) capacitor can provide the best combination of low ESR. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the V_BAT pins. The capacitors should be placed close to the ME3630s V_BAT pins. The following figure shows structure of the power supply. Figure 2-2 Structure of the Power Supply NOTES: The rated current of FB1 should be more than 2.5A. The PCB traces from the V_BAT pins to the power source must be wide enough to ensure that there isnt too much voltage drop occurs in the transmitting procedure. The width of V_BAT trace should be no less than 2mm, and the principle of the V_BAT trace is the longer, the wider. In poor situation of the network is, the antenna will transmit at the maximum power, and the transient maximum peak current can reach as high as 2A. So the power supply capacity of system board needs to be above 2.5A to satisfy the requirement of module peak current; and the average current on the system side needs to be above 0.9A. 2.4.3. REFERENCE CIRCUIT OF POWER SUPPLY

Option One: DC\DC switching The over-current capability requirement of DC/DC switching power supply needs to be above 2.5A. The reference circuit of AAT2138 shows as figure below. Place a tantalum capacitor of 330uF at the input of the chip. Place a 220uF and 33uF capacitor tantalum capacitors at the output of the chip. This circuit fully meets the module power requirements.

Option Two: LDO The over-current capability of LDO is above 2.5A. As the poor transient response of linear regulator, large capacitors should be placed at the input and output of LDO, place a capacitor above 100uF at output of LDO,R2R3 recommend 1% accuracy. The reference power supply circuit design with LDO is shown as figure below:

1. R14~R16 and D6 are applied to suppress the EMI spurious transmission and enhance the ESD protection.D6 should be closed to J4 2.The value of C33 shoule be less than 1uF. In order to enhance the reliability and availability of the USIM card in customers application, please follow the following criterion in the USIM circuit design:

Keep layout of USIM card as close as possible to the module. Assure the possibility of the length of the trace is less than 50mm. Keep USIM card signal away from RF and V_BAT alignment. Assure the ground between module and USIM cassette short and wide. Keep the width of ground and USIM_VCC no less than 0.5mm to maintain the same electric potential. The decouple capacitor of USIM_VCC should be less than 1uF and must be near to USIM cassette. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away with each other and shield them with surrounded ground. In order to offer good ESD protection, it is recommended to add TVS such as WILL (http://www.willsemi.com) ESDA6V8AV6. The 33 resistors should be added in series between the module and the USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. Please note that the USIM peripheral circuit should be close to the USIM card socket. The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion is applied.

ANTENNA INTERFACE ME3630 Hardware Development Guide ME3630 antenna interface includes a main antenna, an optional Rx-diversity antenna, which is used for improve receiving performance. The antenna interface has an impedance of 50. 3.1. PIN DEFINITION The main antenna and Rx-diversity antenna pins definition are shown below. Table 3-1 Pin Definition of GPIO Pin Name Pin NO. I/O Description Comment MAIN_ANT DIV_ANT GPS_ANT 62 79 10 IO AI IO Main antenna 50 impedance Diversity antenna 50 impedance GPS antenna 50 impedance 3.2. REFERENCE DESIGN The antenna is a sensitive device and its performance is greatly affected by external environments. The radiation performance of the antenna is affected by the module dimensions, antenna position, occupied space size of the antenna, and the grounding of surrounding components of the antenna. Besides, the fixed assembly of the antenna, the wiring of RF cables on the antenna, and the fixed position of the antenna all affect the radiation performance of the antenna too. The reference design of main antenna and Rx-diversity antenna is shown as below. It should reserve a -type matching circuit for better RF performance, and place these components as close as possible to the module. The capacitors are not mounted by default. DIV_ANT 0 0 MAIN_ANT NC NC NC NC GPS_ANT 0 NC NC Figure 3-1 Reference Circuit of Antenna Interface NOTE: Keep a proper distance between main and diversity antenna to improve the receiving sensitivity. GNSS and Rx-diversity are not supported by C1B, therefore GNNS antenna design is not concerned in C1B type. 3.3. REFERENCE PCB LAYOUT OF ANTENNA Please follow the following criterion in the process of antenna line PCB layout design:

Make sure that the transmission lines characteristic impedance is 50ohm;

Keep line on the PCB as short as possible, since the antenna line loss shall be less than 0.3 dB;

Line geometry should have uniform characteristics, constant cross section, avoid meanders and abrupt curves;

It is wise to surround the PCB transmission line with ground, avoid having other signal tracks facing directly the antenna line All Rights reserved, No Spreading abroad without Permission 24 track. ME3630 Hardware Development Guide Keep at least one layer of the PCB used only for the ground plane; and use this layer as reference ground plane for the transmission line;

The ground surrounding the antenna line on PCB has to be strictly connected to the main Ground Plane by means of via holes (once per 2mm at least), placed close to the ground edges facing line track;

Place EMI noisy devices as far as possible from modules antenna line;

Keep the antenna line far away from the module power supply lines;

If EM noisy devices are present on the PCB hosting the Module, such as fast switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with ground planes, or shield it with a metal frame cover. 3.4. SUGGESTIONS FOR EMC & ESD DESIGN 3.4.1. EMC DESIGN REQUIREMENTS During the design of the whole device, the user needs to fully consider the EMC problem caused by the signal integrity and power integrity. During the product design, it is better to separate the module from the mainboard PCB, instead of installing the module on the ground of the mainboard. If they cannot be separated, the module should be far from modules and components that might generate EMI, such as chip and memory, power interface, and data cable interface. Because the mainboard of PAD, CPE, and Internet laptops does not have a shielding cover, as that of mobile terminals, to shield most circuits to avoid overflow of electromagnetic interference, you can spray conductive paint on the surface on non-antenna areas within the structural components above and below the mainboard, and the conductive paint should be connected to the ground on the mainboard by several points to shield electromagnetic interference. Besides, data cables of the LCD and the camera might introduce interference signals, which affect the receiving performance of the antenna. Thus, it is necessary to wrap conductive cloth around the two data cables and connected them to the ground. RF cables of the antenna should be far from modules and components that might generate EMI, such as chip and memory, power interface, and data cable interface. The wiring of RF cables should be close to the ground of the mainboard. During the layout and wiring of peripheral circuits, for the wiring of power and signal cables, keep a distance of 2 times of the line width, so as to effectively reduce the coupling between signals and keep a clean reflux path for the signal. During the design of peripheral power circuits, the de-coupled capacitor should be placed closed to the module power PIN, the high-frequency high-speed circuit and the sensitive circuit should be placed far away from the border of PCB. They should better be separated during layout, so as to reduce the interference between them and protect the sensitive signal. For the circuit or device on the side of system board that might interfere with the module, it should be shielded during design. 3.4.2. ESD DESIGN REQUIREMENTS Module is embedded on the side of system board, so the user needs to make the ESD protection during design. For the key input/output signal interface, such as the (U)SIM card signal interface, the ESD device should be placed closely for protection. Besides, on the side of main board, the user should reasonably design the structure and PCB layout, guarantee that the metallic shielding shell is fully grounded, so as to leave a smooth discharge channel for ESD.

SMT PROCESS AND BAKING GUIDE ME3630 Hardware Development Guide This chapter describes modules storage, PAD design, SMT process parameters, baking requirements, etc., and it is applicable for the process guide to second-level assembly of LCC encapsulation module. 7.1. STORAGE REQUIREMENTS Storage conditions: temperature<40, relative humidity<90% (RH), 12 months weld ability guaranteed under this circumstances of excellent sealing package. The Moisture sensitivity level for all modules is level 3 (Conforming to IPC/JEDEC J-STD-020). After opening the package, mount within 168 hours under the environment conditions of temperature<30, relative humidity<60% (RH). If it doesnt meet the above requirements, perform the baking process. See the baking parameters in Table below:

Temperature Baking conditions Baking time Remarks Table 7-1 Baking parameters 125 5 45 5 Moisture: 60%RH 8 hours The accumulated baking time must be less than 96 hours Moisture: 5%RH 192 hours The products transportation, storage and processing must conform to IPC/JEDEC J-STD-033 When in the process of PAD designing of module, refer to IPC-SM-782A and the chapter 6.2 below. 7.2. MODULE PLAINNESS STANDARD Plainness of the module is required to be less than 0.15mm. Measurement method: put the module on the marble plane, use the feeler gage to measure the gap width at the position of maximum warp, and do not exert force on the module during the measurement. 7.3. PROCESS ROUTING SELECTION The modules are manufactured with the lead-free process and meet the ROHS requirements, therefore its recommended to follow the lead-free manufacturing process upon the selection of process routing for module board and main board. 7.3.1. SOLDER PASTE SELECTION The solder pastes with metal particle TYPE3 and TYPE4 can fulfill the welding requirements. It is accordingly recommended to use the no-clean solder paste. If the solder paste which needs cleaning is used, we cannot guarantee the components on the module board could withstand the washing of the cleaning solvents. This might cause the functional problems of such components and affect the appearance of the module. During the printing process, make sure the solder pastes thickness at the position of modules PAD is within 0.18mm~0.20mm. 7.3.2. DESIGN OF MODULE PADS STEEL MESH OPENING ON MAIN BOARD The thickness of the steel mesh on main board is selected according to the encapsulation type of components on the main board. Pay attention to the following requirements:

Make sure to design the module PAD on main board according to chapter 5. The thickness of steel mesh is 0.15mm or 0.18mm, but the thickness at the position of module pad can be increased to 0.18~0.20mm or the thickness of steel mesh is directly 0.18mm~0.20mm on main board. Requirements on the thickness of solder paste: control the thickness between 0.18mm and 0.20mm. See the LCC module PADs steel mesh opening in the following table:

The tape reels, which are suitable for SMT, have been made for most ZTE modules. If the module has provided the tape reel itself and meets the SMT requirements, customers can directly use it for module SMT. Figure 7-2 Material Module Pallet NOTE: Figure7-3 is just for reference, it doesnt represent the actual Material Module Tape Reel. Otherwise, customers need make a loading tool similar to the tape reel. Customers can take out the module from the packaging box, put them into the tape according to the sequence and direction, and then start SMT. 2 Tape Reel Dimension (unit: mm):

Figure 7-3 Tape Reel Dimension 3 Mounting Pressure:

In order to ensure a good contact between the module and the solder paste on main board, the pressure of placing the module board on main board should be 2-5N according to our experiences. Different modules have different numbers of pads, therefore the pressure selected are different. Customers can select proper pressure based on their own situations to suppress the module paste as little as possible, in order to avoid the surface tension of the solder paste melts too much to drag the module during reflow. 7.3.4. MODULE SOLDERING REFLOW CURVE Module soldering furnace temperature curve is:

Peak value: 245+0/-5

217: 3060S

150200: 60120S

Temperature rise slope: <3/S

Temperature drop rate: 24/S All Rights reserved, No Spreading abroad without Permission 38 ME3630 Hardware Development Guide NOTE: The test board of furnace temperature must be the main board with the module board mounted on, and there must be testing points at the position of module board. 7.3.5. REFLOW METHOD Figure 7-4 Module Furnace Temperature Curve Reference Diagram If the main board used by customers is a double-sided board, it is recommended to mount the module board at the second time. In addition, it is preferable for the main board to reflow on the mesh belt when mounting at the first time and the second time. If such failure is caused by any special reason, the fixture should be also used to make such main board reflow on the track so as to avoid the deformation of PCB during the reflow process. 7.3.6. MAINTENANCE OF DEFECTS If poor welding occurs to the module board and main board, e.g., pseudo soldering of the module board and main board, the welder can directly use the soldering iron to repair welding according to the factorys normal welding parameters. All Rights reserved, No Spreading abroad without Permission 39 7.4. MODULES BAKING REQUIREMENTS The module must be baked prior to the second reflow. 7.4.1. MODULES BAKING ENVIRONMENT ME3630 Hardware Development Guide The operators must wear dust-free finger cots and anti-static wrist strap under the lead-free and good static-resistant environment. Refer to the following environment requirements:

WARNING:

The products transportation, storage and processing must conform to IPC/JEDEC J-STD-033. 7.4.2. BAKING DEVICE AND OPERATION PROCEDURE Baking device: Any oven where the temperature can rise up to 125C or above. Precautions regarding baking: during the baking process, the modules should be put in the high-temperature resistant pallet flatly and slightly to avoid the collisions and frictions between the modules. During the baking process, do not overlay the modules directly because it might cause damage to the modules chipset. 7.4.3. MODULE BAKING CONDITIONS See the baking parameters in Table 7-1. 8.
