Chapter 7. Important Notes

7.1 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 PCB

assembly by post, in that it would avoid unnecessarily lost or damage.

7.2 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 form

one speaker system, so that you may have the as many speaker systems.
