1.  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.   
2.  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.   
3.  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.
