Introduction
This document defines the SC20 module and describes its air interface and hardware interface which are
connected with your application.
This document can help you quickly understand module interface specifications, electrical and
mechanical details as well as other related information of SC20 module. Associated with application notes
and user guide, you can use SC20 module to design and set up mobile applications easily.
1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating SC20 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel and to incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the
customer’s failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an
accident. Using a mobile while driving (even with a handsfree kit) causes
distraction and can lead to an accident. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers an
Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals or clinics or other health care
facilities. These requests are desinged to prevent possible interference with
sentitive medical equipment.

Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid SIM card. While you are in this condition and need emergent
help, please remember using emergency call. In order to make or receive a call,
the cellular terminal or mobile must be switched on and in a service area with
adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON ,
it receives and transmits radio frequency energy. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potencially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potencially exposive atmospheres include fuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles such as grain, dust or metal powders, etc.
Please do not discard. Maybe wireless devices have an impact on the environment
so please do not arbitrarily discarded.
The device is restricted to indoor use only when oparating in the 5150 to 5350 Mhz
frequency range.

NOTES
1)
Within operation temperature range, the module is 3GPP compliant.
Within extended temperature range, the module remains the ability to establish and maintain a voice,
SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There are also no
effects on radio spectrum and no harm to radio network. Only one or more parameters like Pout might
reduce in their value and exceed the specified tolerances. When the temperature returns to the normal
operating temperature levels, the module will meet 3GPP compliant again.
* means this feature is under development.

1. 1) Operating temperature range ---- 3GPP compliant.
2)
Within extended temperature range, the module remains the ability to establish and maintain a voice,
SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There are also no
effects on radio spectrum and no harm to radio network. Only one or more parameters like Pout might
reduce in their value and exceed the specified tolerances. When the temperature returns to the normal
operating temperature levels, the module will meet 3GPP compliant again.

7.6. Electrostatic Discharge
The module is not protected against electrostatic discharge (ESD) in general. Consequently, it should be
subject to ESD handling precautions that are typically applied to ESD sensitive components. Proper ESD
handling and packaging procedures must be applied throughout the processing, handling and operation
of any application that incorporates the module.

Storage, Manufacturing and
Packaging
9.1. Storage
SC20 is stored in a vacuum-sealed bag. The restrictions of storage condition are shown as below.
1.
2.
3.
4.
Shelf life in sealed bag is 12 months at < 40ºC/90%RH.
After this bag is opened, devices that will be subjected to reflow soldering or other high temperature
process must be:
 Mounted within 72 hours at factory conditions of ≤ 30ºC/60%RH.
 Stored at < 10% RH.
Devices require baking before mounting, if:
 Humidity indicator card is > 10% when ambient temperature is 23ºC±5ºC.
 Mounting cannot be finished within 72 hours at factory conditions of ≤ 30ºC/60% RH.
If baking is required, devices may be baked for 48 hours at 125ºC±5ºC.
NOTE
As plastic package cannot be subjected to high temperatures, the package must be removed from
devices before high temperature (125ºC) baking. If shorter baking time is desired, please refer to
IPC/JEDECJ-STD-033 for baking procedure.
9.2. Manufacturing and Welding
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. The force on the squeegee should be adjusted properly
so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the
thickness of stencil at the hole of the module pads should be 0.18mm. For details, please refer to
document [3].

Figure 8: Recommended Stencil Design for LGA Pads
It is suggested that the peak reflow temperature is from 235 to 245ºC (for SnAg3.0Cu0.5 alloy). The
absolute maximum reflow temperature is 260ºC. To avoid damage to the module caused by repeated
heating, it is suggested that the module should be mounted after reflow soldering for the other side of
PCB has been completed. Recommended reflow soldering thermal profile is shown below:

11 Appendix B GPRS Multi-slot Classes
Twenty-nine classes of GPRS multi-slot modes are defined for MS in GPRS specification. Multi-slot
classes are product dependent, and determine the maximum achievable data rates in both the uplink and
downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots,
while the second number indicates the amount of uplink timeslots. The active slots determine the total
number of slots the GPRS device can use simultaneously for both uplink and downlink communications.
The description of different multi-slot classes is shown in the following table.

harmful interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved by the party responsible for compliance
could void the user‘s authority to operate the equipment.
14.2. RF Exposure Information
This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In
order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity
to the antenna shall not be less than 20cm (8 inches) during normal operation.

In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to be
informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment can be
satisfied. The end user has to also be informed that any changes or modifications not expressly
approved by the manufacturer could void the user's authority to operate this equipment. If the size of
the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be
available in the users manual: This device complies with Part 15 of FCC rules. Operation is subject to
