7.1 Packing Requirement or Sending the PCB Assembly by Post
PCB assembly is a kind o 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 PCB
assembly by post, in that it would avoid unnecessarily lost or damage.
7.2 Short o Spare Parts while Repairing a Speaker System
I you are short o spare parts when you have some speaker systems waiting
to be repaired, it would be recommended to take the necessary parts orm
one speaker system, so that you may have the as many speaker systems.
