7.1 Packing Requirement for Sending the PCB Assembl b Post
PCB assembl is a kind of sophisticated electronic circuit board. Well
packing will be required when sending them b post.
* Some sophisticated IC components are mounted on the PCB assembl ,
hence it is necessar to pack each PCB assembl with a separate static
protecting bag, in order to avoid static electricit .
* Reliable external packing is also ver important when sending PCB
assembl b post, in that it would avoid unnecessaril lost or damage.
7.2 Short of Spare Parts while Repairing a Speaker S stem
If ou are short of spare parts when ou have some speaker s stems waiting
to be repaired, it would be recommended to take the necessar parts form
one speaker s stem, so that ou ma have the as man speaker s stems.
