1. 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.
2. Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the
module.
3.
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 [5]
