Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 42 MF206A 3.12.2 Power-on/Power-off Flow To guarantee the user can power on and power off stably, you can refer to the power-on sequence chart as shown in Figure 3-11 and the power-off sequence chart as shown in Figure 3-12. Table 3-11 shows the power-on and resetting time, which needs to be paid attention to during the module power-on process. 1. Once VPH_PWR is powered on, the POWER_ON signal will be synchronized and be established as the high PWL. 2. After VPH_PWR is established normally, the interval between it to the POWER_ON signal cannot be too short. Refer to T2 parameter. ZTEWelink recommends that VPH_PWR adopt the power-off plan that does not disconnect the power supply. 3. The power-on startup time takes the lower level of POWER_ON as the starting point, and POWER_ON needs to be released after being kept on the low PWL for a period. 4. SUB_VBUS is the USB PHY power supply. It is not recommended to be established before VPH_PWR. During the process of establishing the module PINs, pay attention to the following items: 1. To power off by the POWER_ON signal, the T4 period needs to be designed as required. 2. After VPH_PWR and USB_VBUS are powered off, it is recommended not to disconnect the power supply.

Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 45 MF206A 3.13.2 Interface Application The module provides 5 handshake signals for the communication with the application processor (AP). By MODULE_POWERON, AP can query whether LGA is powered on and is working normally. By MODULE_READY, AP queries whether the LGA module has entered the sleep status, wakes up the module under the sleep status by AP_WAKEUP _MODULE. In the same way, when AP is in the sleep status, the LGA module can query the AP status by AP_READY, and wakes up AP by MODULE _WAKEUP_AP. AP_READY: Indicates that the AP server is sleep: the high PWL indicates the sleep status, and the low PWL indicates the wakeup status. MODULE_READY: Indicates that the module is sleep: the high PWL indicates the sleep status, and the low PWL indicates the wakeup status. AP_WAKEUP_MODULE: After the module has entered the sleep status, the AP server can wake up the module by the low PWL control; if it’s always on the low PWL, the module cannot enter the sleep status. After the AP server enters the high PWL, the module enters the sleep status. MODULE_WAKEUP_AP: After the AP server has entered the sleep status, the module can lower down this signal to wake up the AP server. After the module has queried that the server sleep indicator AP_READY is low, it resets this signal to high. MODULE_POWERON: After the module is powered on, this signal is set to high, and kept until the system is restarted or powered down. Low signal indicates that the server is not powered on, during the power-on process or is being restarted. 3.14 LED Indicator Interface 3.14.1 Description of PINs Table 3–13 Definition of LED PIN Signal PIN Signal Name I/O Type Function 20.

The voltage design of external circuit interfaces should match that of the module PINs, and the detailed value can be got in Table 3-2. The module product has a good RF indicator; customers can refer to the Chapter 5 of Antenna Design Guide of Module Product in the process of antenna circuit designing. Otherwise it will affect the whole RF performance. 4.2 Power Supply Requirement The power supply of ZTEWelink LGA Type module is usually recommended to be within the range of 3.4~4.2V. According to the requirement of mobile terminal device, the power supply voltage of module is 3.8V under normal working condition.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 48 MF206A In poor situation of the network, 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 2.0A. Meanwhile, consider the voltage drop of power supply on the side of main board. If the network is in a poor situation or under 2G, the module peak current will be great, Therefore the power supply has to be designed in order to withstand with these current peaks without big voltage drops; this means that both the electrical design and the board layout must be designed for this current flow. If the layout of the PCB is not well designed a strong noise floor is generated on the ground and the supply; and exceptions such as restart of the module may occur. The peak current of ZTEWelink module under the GSM BURST mode is different due to the differences in actual network environments. And its transient current under different powers will be various as well. The greater the power is, the greater the transient current is. The network quality also directly affects the work current of the module. If the network is in well situation, the peak work current on the module will be small. But if the network is in poor situation, its peak current will be great as shown in Figure 4-1. When ZTEWelink module works under the EDGE/GPRS Time Slot (2-high 6-low) and CLASS 10, if the module works under the 2-high work Time Slot, it requires greater current, and the voltage drop will occur accordingly.

Advantage: Can provide well transient current under 2G weak signal environment to satisfy modules requirements, to prevent device from shutdown and Ports re-enumeration as a consequence of the supply voltage drop.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 50 MF206A The over-current capability requirement of DC/DC switching power supply need to be above 3A, for example,ZI1153, AAT2138 and so on. Input voltage range of ZI1153 is: 2.5～5.5V，output voltage range of ZI1153 is from 0.6V to VIN( input voltage). Input voltage range of AAT2138is: 2.7～5.5V，output voltage range of AAT2138 is from 3.3～5.5V. As shown in the Figure below, use DC/DC switching power supply ZI1153 as the buck chip. Place a tantalum capacitor of 330μF at the input of the chip. Place a 2200μF capacitor or place several 330μF tantalum capacitors in parallel. This circuit fully meets the module power requirements. (If the user’s PCB size is limited, the output of buck chip can place three more 330μF tantalum capacitors of which the total capacity is more than 1000μF) Figure 4–3 DC/DC Switching Power Supply Vin=5V Vout=3.8V Option two: Use LDO as the buck chip. The over-current capability of LDO is above 3A. As the poor transient response of linear regulator, large capacitors should be placed at the input and output of LDO. The output of LDO, place a capacitors above 2000μF. The reference power supply circuit design with LDO is as shown in Figure below.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 51 MF206A Figure 4–4 LDO Power Supply 4.5 PCB Layout Guideline of Power Supply As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances. The users of ZTEWelink modules should do as the following guidelines in the process of power supply PCB line designing: The use of a good common ground plane is suggested. The placement of the power supply on the board should be done in such a way to guarantee that the high current return paths in the ground plane are not overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or earphone amplifier. The power supply input cables should be kept separate from noise sensitive lines such as microphone/earphone/RF cables. The Bypass low ESR capacitor must be placed close to the ZTEWelink module power input pads, or in the case the power supply is a switching type it can be placed close to the inductor to cut the ripple provided the PCB trace from the capacitor to the module is wide enough to ensure a dropless connection even during the 2.5A current peaks. The protection diode must be placed close to the input connector where the power source is drained. The PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occur when the 2.5A current peaks are absorbed. Note that this is not made in order to save power loss but especially to avoid the voltage drops on the power line at the current peaks frequency that will reflect on all the
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 52 MF206A components connected to that supply, introducing the noise floor at the burst base frequency. For this reason while a voltage drop of 300-400 mV may be acceptable from the power loss point of view, the same voltage drop may not be acceptable from the noise point of view. If your application doesn't have audio interface but only uses the data feature of the ZTEWelink module, then this noise is not so disturbing and power supply layout design can be more forgiving. The PCB traces to the ZTEWelink module and the Bypass capacitor must be wide enough to ensure no significant voltage drops occur when the 2.5A current peaks are absorbed. This is for the same reason as previous point. Try to keep this trace as short as possible. The PCB traces connecting the Switching output to the inductor and the switching diode must be kept as short as possible by placing the inductor and the diode very close to the power switching IC (only for switching power supply). This is done in order to reduce the radiated field (noise) at the switching frequency (100-500 kHz usually).
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 53 MF206A 5 RF Antenna Design Guide The antenna connection and board layout design are the most important aspect in the full product design as they strongly affect the product overall performances, hence read carefully and follow the requirements and the guidelines for a proper design. 5.1 Antenna Types Antenna types and modes are different according to the different ID designs and circuit layout designs of the product itself. You can choose the antenna type and mode according to the estimation result by antenna engineers. 1. For PAD products, because the product itself has low sections, usually printed antennas are used as the antenna mode (the antenna wiring is printed on a thin PCB board), and IFA plus parasitic units or monopole plus parasitic units are used as the antenna type. 2. For CPE products, because most products of this type have a large size, the available space for antennas is also relative large. Thus, this type of products usually adopts the mode of PC racks plus FPC antennas or PC racks plus bullet antennas. IFA plus parasitic units or monopole plus parasitic units are used as the antenna type. 3. If the product supports external antenna, then switch between the external antenna and internal antenna must be using mechanical switches instead of electronic switches. 5.2 Antenna RF Cable and RF Connector 5.2.1 RF Connector There are two interfaces on the RF antenna of module: main antenna interface, and GPS antenna. The main antenna supports two access modes of RF signal: by LGA wielding panel mode and by RF connector mode. The GPS antenna only supports the access mode of LGA wielding panel. Figure 5-1 is the main antenna connector
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 54 MF206A interface, and Figure 5-2 is the Interface of Main Antenna and GPS Antenna Welding Pad. Figure 5-3 shows the main antenna RF connector. Currently, ZTEWelink module adopts the ECT818000157 RF connector testing console from ECT Company. Figure 5–1 Main Antenna RF Connector Interface Figure 5–2 Interface of Main Antenna and GPS Antenna Welding Pad
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 55 MF206A Figure 5–3 RF Interface Testing Console Figure 5–4 Profile Dimensions of RF antenna console If the main antenna is access by the RF connector, the using of corresponding cables of RF interface are recommended. When this connection mode is adopted, the RF antenna connector can be directly inserted to the RF testing console of the module, so it saves the connection between the RF port and the antenna interface. If the main antenna is accessed by the LGA wielding panel, the RF main antenna wield pane of the module itself needs to be connected to the antenna interface on main board via the wield pane and micro stripline or stripline. The micro stripline or stripline is designed according to the 50ohm impedance, and the dual-L model matching circuit is reserved. RF interface on ZTEWelink module is ECT818000157. Because this type of RF interfaces requires RF cables with smaller diameters and larger consumptions, it is usually recommended not to directly connect RF connectors of antenna RF cables with RF interfaces on the module, and it is recommended to convert them into
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 56 MF206A common interfaces by conversion circuits, such as ECT818000071 of I-PEX and U.FL-R-SMT-1(80) of HIROSE. The design of GPS antenna is consistent with the main antenna, and its efficiency index is allowed to be 3dB lower. The separation degree between the main antenna and the diversity antenna is required to be greater than 12dB. 5.2.2 RF Cable If the diameter of RF cables used by the antenna is different, its consumption is also different. During the 2G/3G/LTE communication, usually RF cables with a diameter of 1.37mm or 1.13mm are adopted. It is recommended to select the RF coaxial cable with a diameter of 1.37mm because it has less consumption. There are many manufacturers of RF cables, such as GBE in Taiwan, Shenyu and Yuanda in China mainland, SUMITOMO and Shin Din in Japan. All of these manufacturers provide RF cables of more than two specifications. The following tables describe RF cables of several specifications. The Standard Value of cable (RF137XR4 of GBE, RF-1.37 of Shenyu, 0.8DS-PBM(1.35) of SUMITOMO) consumption is shown as Table 5-1 below (Unit: dB/m): Table 5–1 The Cable Consumption Frequency RF137XR4 of GBE RF-1.37 of Shenyu 0.8DS-PBM(1.35) 0.4GHz 1.0 -- -- 0.8GHz 1.5 -- -- 1.0GHz 1.6 ≤1.7 ≤1.5 1.5GHz 2.0 -- -- 2.0GHz 2.3 ≤2.5 ≤2.2 2.4GHz -- -- ≤2.6 3.0GHz 2.9 ≤3 ≤2.8 4.0GHz -- ≤3.5 ≤3.4 5.0GHz -- ≤4 ≤3.8 5.2GHz 4.0 -- -- 5.8GHz 4.2 -- -- 6.0GHz 4.3 ≤4.5 ≤4.3
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 57 MF206A Because RF cables used by the antenna inevitably introduce certain loss, it is necessary to consider the wiring length of RF cables during the design of module position and antenna position. It is recommended to control the length within the loss range of 0.5 dB (HF). During the wiring design of antenna RF cables, avoid right angle, pressed and wearing. The recommended receptacles Mode of ECT 818000157 is ECT 818000160 as shown below: Figure 5–5 Recommended Receptacles Mode for module 5.3 Design of Antenna 5.3.1 Preliminary Antenna Evaluation 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 mainboard 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. Thus, during the preliminary design phase of an antenna, it is critical that antenna engineers, RF engineers, baseband engineers, structure engineers, and ID engineers work together to make an estimation for both 2D and 3D design. The antenna interface should have an impedance of 50Ω.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 58 MF206A 5.3.2 Suggested Antenna Location During the design of the board with ZTEWelink module, the placement of components should be placed properly, and keep the line length as short as possible, thus leading to lowest power losses possible. Usually, the antenna position is designed according product features and antenna shall not be installed inside metal cases. For example, for Internet laptops and PAD products, the ideal position of antennas is on the top left corner or top right corner of the LCD, which is relatively far from the mainboard, so the electromagnetic interference is relatively small. Besides, because it is far from human bodies, it is easy to satisfy SAR indexes. For PAD products or Internet laptops, the ideal position is where hands rarely touch, so the impact from hand holding is the minimum. The above example only considers the antenna position area in a specific scenario. For the specific position, it is critical to determine with antenna engineers, RF engineers, baseband engineers, structure engineers, and ID engineers during the 2D/3D estimation phase according to the specific product. Antenna shall be installed also according to antenna manufacturer instructions. 5.3.3 Suggested Antenna Occupancy Space For different product types, because their frequency bands are different, required occupation space of the antenna is also different. For the specific antenna space, it is critical to estimate it with antenna engineers, RF engineers, baseband engineers, structure engineers, and ID engineers during the 2D/3D estimation phase. Taking the PAD product with a dimension of 95 mm * 125 mm (length * width) as an example, if the antenna should cover 824-960 MHz and 1710-2170 MHz, it is recommended to reserve the following antenna space: if the printed antenna mode is adopted, the reserved space should be above 75mm*10mm (length*width); if the antenna mode of PC rack plus FPC or PC rack plus spring is adopted, the reserved space should be above 70mm*10mm*3mm (length*width*height). 5.3.4 Matching Circuit of Antenna For all products with ZTEWelink module, the antenna is basically connected to the module through RF cables and RF connectors. This section describes two situations. 1. If the RF terminal connector of the module does not match the RF cables used by the antenna, or the direct connection between the RF antenna mated connector of RF cables and the RF port of the module is
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 59 MF206A restricted by the height, a circuit is required between them for transition. During the design of transit circuits on the mainboard, the natural impedance of the microstrip line or stripline between the RF port of the module and the RF port on the mainboard connected to the antenna is designed to be 50 ohm, and a dual-L matching circuit is reserved, as shown in Figure 5-6. Use a zero-ohm resistor on the cascading position between them. 2. If the RF connector used by the RF cable can be directly connected to the RF terminal on the module, and the height falls within the limited range, the circuit transition between the RF port on the module and the antenna interface can be saved, and the RF connected used by the RF cable of the antenna can be directly connected to the RF terminal of the module.

The antenna RF cable usually adopts a line width of 1.37mm. The antenna RF connector usually adopts Japanese IPX, or HRS, while the price of the latter is higher.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 60 MF206A 5.4 Recommended Antenna Manufacturers Many domestic antenna manufacturers in China can design proper matched antennas according to specific products. This section recommends several antenna manufacturers with strong integrative strength in the mobile terminal industry, which have powerful hardware resources and software resources, experienced antenna design engineers, and advanced antenna test systems (including antenna Passive test, Passive OTA test, and SAR test) to satisfy various customer requirements. 1. Ethertronics at Shanghai 2. Skycross at Shanghai 3. Laird at Beijing 4. Sherbed at Suzhou 5. Yaodeng Electronic Communication Technology (kunshan) Co., Ltd. 5.5 PCB line guidelines The users of ZTEWelink modules should do as the following guidelines in the process of RF PCB line design: 1. Make sure that the transmission line’s characteristic impedance is 50ohm ; 2. Keep line on the PCB as short as possible, since the antenna line loss shall be less than around 0,3 dB; 3. Line geometry should have uniform characteristics, constant cross section, avoid meanders and abrupt curves; 4. If a Ground plane is required in line geometry, that plane has to be continuous and sufficiently extended, so the geometry can be as similar as possible to the related canonical model; 5. It is wise to surround (on both sides) the PCB transmission line with Ground, avoid having other signal tracks facing directly the antenna line track. 6. Keep, if possible, at least one layer of the PCB used only for the Ground plane; If possible, use this layer as reference Ground plane for the transmission line; 7. Avoid crossing any un-shielded transmission line footprint with other signal tracks on different layers;
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 61 MF206A 8. 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; 9. Place EM noisy devices as far as possible from modules antenna line; 10. Keep the antenna line far away from the module power supply lines; 11. If EM noisy devices are present on the PCB hosting the ZTEWelink 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. 5.6 Suggestions for EMC & ESD Design 5.6.1 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. 1. 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. 2. 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. 3. 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. 4. 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.
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 62 MF206A 5. 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. 6. 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. 7. For the circuit or device on the side of system board that might interfere with the module, it should be shielded during design. 5.6.2 ESD Design Requirements MF206A 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. 5.7 Antenna Indexes The module supports the AGPS/GPS function, so the system equipment needs to add the GPS antenna. The design of GPS antenna is consistent with that of the main antenna, and its efficiency index can be 3dB lower. The separation degree between the main antenna and the diversity antenna is required to be greater than 12dB. The antenna index is divided into the Inactive index and Active index. The Inactive index includes S11, efficiency, gains, orientation diagram and polarity, which can be used as the parameter measuring the performance of the antenna itself. The Active index is also called the OTA index, including TRP (all-round radiation power), TIS (all-round receiving sensitivity), radiation orientation diagram, which is an important index measuring the radiation performance of the whole set (including the antenna, module, main board).
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 63 MF206A 5.7.1 Passive Indexes Different products have different requirements for antenna performance. The following table describes wireless indexes for PAD products as a reference to users, but the radiation performance of the antenna is finally determined by Active indexes. Table 5–2 Passive Indexes of Main Antennas on PAD Products Frequency 824-960MHz 1710-2170MHz VSWR <3.5:1 <3.5:1 Maximum gains >0dBi >0dBi Average gains >-3.5dBi >-3.5dBi Efficiency >40% >40% 5.7.2 Active Indexes Active indexes are important indexes measuring the radiation performance of the whole mobile phone (including the antenna, module, and mainboard), thus they determine the final radiation performance of the terminal product. However, different products have different Active indexes, and different carries have different requirements for Active indexes as well. Thus, antenna engineers, RF engineers, baseband engineers, structure engineers, and ID engineers should work together to estimate the performance of the board during the project preliminary phase according to the Active indexes. There is no universal international standard for mobile terminal products, so mobile terminals are all designed according to the carrier requirements. Table 5-3 describes the requirement of Active indexes by ZTEWelink for Mobile Terminal Devices as a reference to users.

Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 77 MF206A 9 Design Guide This chapter provides the general design guide for module, used as a reference for the user during the design process, so that the product can reach better performance. 9.1 General Design Rule & Requirement When the user is designing the peripheral circuits of module, he needs to first guarantee that the external circuit has the sufficient power supply capability, and the USB of high-speed signal cable is required to have 90ohm differential resistance. For the common signal interface, it is required to design according to ZTEWelink requirements, which needs to comply with the power level of interface signal, so as to prevent the impedance from damaging the module. The RF index of this product itself is good, and the user needs to design the antenna circuit of the main board and make the corresponding impedance control. Otherwise, the RF index of the whole set will be affected. 9.2 Suggestions for PCB Wielding Panel Design When the user is designing the encapsulation wielding panel on main board, the 30 heat wielding panels in the center are recommended to be designed according to the dimensions as described in Figure 9-1. The surrounding 78 wielding panels should be extended by more than 0.3mm, and the other three sides of the wielding panel are extended by 0.05mm. For the right angles of wielding panels for the main antenna PIN1 and GPS antenna PIN70, they are recommended to be rounded into a round angel with a radius of 0.3mm. In this way, it is convenient for the import of interference and the radiation of RF signal. The Recommended PCB Wielding Panel Design is shown in Figure 9-1 (Unit:mm).

The heat dissipation is taken into full consideration during the product design, as 30 heat wielding
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 79 MF206A panels are reserved in the center of the module. During the connection with the system board, make sure that these wielding panes are grounded well, which is greatly helpful to heat conductivity and heat balance, and is greatly beneficial to the electric performance of the whole set as well.  NOTE: 1. Keep this product away from heat-dissipation devices with high power, to prevent the temperature of the module from being too high. 2. Do not put the module close to the large heat-dissipation devices, such as CPU or bridge. The high temperature will affect the RF performance. 9.4 Recommended Product Upgrading Plan It’s recommended to use the one-click software upgrade tool to upgrade through the USB port provided by ZTEWelink in the Windows system. If the customer wants to upgrade the module in other operation systems, ZTEWelink provides the corresponding reliable tools as well. .

When manufacturing the steel mesh of thermal pad on the bottom of the module, narrow the mouth of the steel mesh of the original size, so as to reduce the risk of shortcut between the module thermal and the peripheral PINs. This method is effective. 2. It is recommended to design to the mouth of steel mesh on the thermal pad wielding panel to the lattice form. Figure 10-1 shows the recommended pattern for the steel mesh. Figure 10–1 Recommended Pattern of Steel Mesh on Wielding panel .
Hardware Development Guide of Module Product All Rights reserved, No Spreading abroad without Permission of ZTEWelink 81 MF206A 10.2 Furnace Temperature Curve The furnace temperature curve greatly affects the wielding quality and the material status, so it needs to be paid great attention to. The temperature increasing speed cannot be too fast, with the increase speed from the room temperature to 150℃ less than 3℃/second. At the same time, if the temperature is above 217℃, the duration should be kept within 70 seconds, while the interim value 55 seconds is ideal. Otherwise, the great temperature shock will make certain devices ineffective, causing the quality to decrease and the maintenance difficulty to increase. At the same, keep the precise maximum temperature to be below 245℃, as certain materials (such as the crystal) might crack under the high temperature and won’t vibrate any more, so the product function is affected. Refer to Table 10-1 for the detailed requirements setting of furnace temperature curve, refer to Figure 10-2 for the furnace temperature curve and the testing result. Table 10–1 Curve Temperature Curve Parameter Setting Lead-free Curve Temperature Curve Phase Temperature Duration Pre-heat Temperature is increased from room temperature to 150℃ Temperature increasing ratio <3℃/second Temperature keeping 150℃~200℃ 40~110 seconds Wielding Greater than 217℃ 40~70 seconds Above 230℃ 15~45 seconds Peak temperature MAX: 245℃ MIN: 230℃
