SMT module de-soldering and rework Guidelines
Figure 8: Pick up the module with a pair of tweezers
z Let the unsoldered SIM300DZ module cool down in the environmental temperature. Assure
the module can not be swashed and overturned during the whole process of cooling down.
Otherwise that may introduce the risk of artificially destruction such as components out of
the position or BGA bridges connection.
