Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service or repair of any cellular or mobile terminal incorporating the module. Manufacturers of the cellular terminal should notify users and operating personnel of the following safety precautions by incorporating them into all product manuals. Otherwise, Quectel assumes no liability for customers’ failure to comply with these precautions.
Full attention must be paid to driving at all times to reduce the risk of an accident. Using a mobile phone while driving (even with a handsfree kit) causes distraction and can lead to an accident. Please comply with laws and regulations restricting the use of wireless devices while driving.
Switch off the cellular or mobile terminal before boarding an aircraft. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. If there is an Airplane Mode, it should be enabled prior to boarding an aircraft. Please consult the airline staff for more restrictions on the use of wireless devices on an aircraft.
Wireless devices may cause interference on sensitive medical equipment, so please be aware of the restrictions on the use of wireless devices when in hospitals, clinics or other healthcare facilities.
Cellular terminals or mobiles operating over radio signal and cellular network cannot be guaranteed to connect in certain conditions, such as when the mobile bill is unpaid or the (U)SIM card is invalid. If emergency assistance is needed, use emergency call if the device supports it. To make or receive a call, the cellular or mobile terminal must be switched on in a service area with adequate cellular signal strength. In an emergency, the device with emergency call function cannot be used as the only contact method since network connection cannot be guaranteed under all circumstances.
The cellular or mobile terminal contains a transceiver. When it is ON, it receives and transmits radio signals. RF interference can occur if it is used close to TV sets, radios, computers, or other electric equipment.
In locations with explosive or potentially explosive atmospheres, obey all posted signs and turn off wireless devices such as mobile phones or other cellular terminals. Areas with explosive or potentially explosive atmospheres include fueling areas, below decks on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles such as grain, dust or metal powders.

4.1.1. Reference Design for Power Supply
The module is powered by VBAT, and it is recommended to use a power supply chip that can provide more than 100mA output current. For better power supply performance, it is recommended to parallel a 22 F decoupling capacitor, and two filter capacitors (1 F and 100 nF) near the module’s VBAT pin. In addition, it is recommended to add a TVS near the VBAT to improve the surge voltage bearing capacity of the module. In principle, the longer the VBAT trace is, the wider it should be.
VBAT reference circuit is shown below:

5.2. Antenna/Antenna Interfaces
Appropriate antenna type and design should be used with matched antenna parameters according to specific application. It is required to perform a comprehensive functional test for the RF design before mass production of terminal products. The entire content of this chapter is provided for illustration only. Analysis, evaluation and determination are still necessary when designing target products.
The module is provided in one of the three antenna/antenna interface designs: pin antenna interface (ANT_BT), PCB antenna and coaxial RF connector. The coaxial RF connector is not available when the module is designed with ANT_BT antenna interface or PCB antenna. The impedance of antenna port is 50 .

5.2.1.3. RF Routing Guidelines
For user’s PCB, the characteristic impedance of all RF traces should be controlled to 50 . The impedance of the RF traces is usually determined by the trace width (W), the materials’ dielectric constant, the height from the reference ground to the signal layer (H), and the spacing between RF traces and grounds (S). Microstrip or coplanar waveguide is typically used in RF layout to control characteristic impedance. The following are reference designs of microstrip or coplanar waveguide with different PCB structures.

Figure 15: Coplanar Waveguide Design on a 4-layer PCB (Layer 4 as Reference Ground)
To ensure RF performance and reliability, follow the principles below in RF layout design:
Use an impedance simulation tool to control the characteristic impedance of RF traces to 50 . GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully
connected to the ground. The distance between the RF pins and the RF connector should be as short as possible and all
right-angle traces should be changed to curved ones. The recommended trace angle is 135°. There should be clearance under the signal pin of the antenna connector or solder joint.

HCM111Z_Hardware_Design

29 / 52

Bluetooth Module Series
The reference ground of RF traces should be complete. In addition, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be at least twice the width of RF signal traces (2 × W).
Keep RF traces away from interference sources, and avoid intersection and paralleling between traces on adjacent layers.
For more details about RF layout, see document [2].

When designed with PCB antenna, the module should be placed on the edge of the motherboard. The PCB antenna should be at least 16 mm away from the metal components, connectors, vias, traces, and copper pour area on the motherboard. On the motherboard, all PCB layers under the PCB antenna should be designed as a keepout area.

8 Storage and Packaging
8.1. Storage Conditions
The module is provided with vacuum-sealed packaging. MSL of the module is rated as 3. The storage requirements are shown below.
1. Recommended Storage Condition: the temperature should be 23 ±5 °C and the relative humidity should be 35­60 %.
2. Shelf life (in a vacuum-sealed packaging): 12 months in Recommended Storage Condition.
3. Floor life: 168 hours 8 in a factory where the temperature is 23 ±5 °C and relative humidity is below 60 %. After the vacuum-sealed packaging is removed, the module must be processed in reflow soldering or other high-temperature operations within 168 hours. Otherwise, the module should be stored in an environment where the relative humidity is less than 10 % (e.g., a dry cabinet).
4. The module should be pre-baked to avoid blistering, cracks and inner-layer separation in PCB under the following circumstances:
The module is not stored in Recommended Storage Condition; Violation of the third requirement mentioned above; Vacuum-sealed packaging is broken, or the packaging has been removed for over 24 hours; Before module repairing.
5. If needed, the pre-baking should follow the requirements below:
The module should be baked for 8 hours at 120 ±5 °C; The module must be soldered to PCB within 24 hours after the baking, otherwise it should be put
in a dry environment such as in a dry cabinet.

8 This floor life is only applicable when the environment conforms to IPC/JEDEC J-STD-033. It is recommended to start the solder reflow process within 24 hours after the package is removed if the temperature and moisture do not conform to, or are not sure to conform to IPC/JEDEC J-STD-033. Do not unpack the modules in large quantities until they are ready for soldering.

HCM111Z_Hardware_Design

44 / 52

Bluetooth Module Series
NOTE 1. To avoid blistering, layer separation and other soldering issues, extended exposure of the module
to the air is forbidden. 2. Take out the module from the package and put it on high-temperature-resistant fixtures before
baking. If shorter baking time is desired, see IPC/JEDEC J-STD-033 for the baking procedure. 3. Pay attention to ESD protection, such as wearing anti-static gloves, when touching the modules.
8.2. Manufacturing and Soldering
Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. Apply proper force on the squeegee to produce a clean stencil surface on a single pass. To guarantee module soldering quality, the thickness of stencil for the module is recommended to be 0.15­0.18 mm. For more details, see document [3].
The recommended peak reflow temperature should be 235­246 ºC, with 246 ºC as the absolute maximum reflow temperature. To avoid damage to the module caused by repeated heating, it is recommended that the module should be mounted only after reflow soldering for the other side of PCB has been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and related parameters are shown below.

NOTE
1. The above profile parameter requirements are for the measured temperature of solder joints. Both the hottest and coldest spots of solder joints on the PCB should meet the above requirements.
2. During manufacturing and soldering, or any other processes that may contact the module directly, NEVER wipe the module’s shielding can with organic solvents, such as acetone, ethyl alcohol, isopropyl alcohol, trichloroethylene, etc. Otherwise, the shielding can may become rusted.
3. The shielding can for the module is made of Cupro-Nickel base material. It is tested that after 12 hours’ Neutral Salt Spray test, the laser engraved label information on the shielding can is still clearly identifiable and the QR code is still readable, although white rust may be found.
4. If a conformal coating is necessary for the module, do NOT use any coating material that may chemically react with the PCB or shielding cover, and prevent the coating material from flowing into the module.
5. Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the module.
6. Due to the complexity of the SMT process, please contact Quectel Technical Support in advance for any situation that you are not sure about, or any process (e.g. selective soldering, ultrasonic soldering) that is not mentioned in document [3].
