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.

6.2 Short of spare parts while repairing a speaker system
If you are short of spare parts when you have some speaker

systems waiting to be repaired, it would be recommended to take
the necessary parts from one

Speaker system, so that you may have the as many speaker

systems
