6.1 Packing requirement for sending the PCB assembly by post 

  PCB assembly is a kind of sophisticated electronic circuit board. Well packing 
  Will be required when sending them by post. 
  *Some sophisticated IC components are mounted on the PCB assembly, hence 
  it is necessary to pack each PCB assembly with a separate static protecting bag, 
  in order to avoid static electricity. 
  *Reliable external packing is also very important when sending the PCB assembly 
  by post, in that it would avoid unnecessarily lost or damage.
