SC20-A_Manual_R1.0 Confidential / Released 5 / 49 1 Introduction This document defines the SC20 module and describes its air interface and hardware interface which are connected with your application. 1.1. Safety Information 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. 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. 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.
SC20-A_Manual_R1.0 Confidential / Released 6 / 49 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.

The restrictions of storage condition are shown as below. 1. Shelf life in sealed bag is 12 months at < 40ºC/90%RH. 2. 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. 3. 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. 4. If baking is required, devices may be baked for 48 hours at 125ºC±5ºC. 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]. 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. NOTE
