Important Notes
Packing requirement for sending the PCB assembly
PCB assembly is a kind of sophisticated electronic circuit board. A scanner mainly includes
the following items: Scan Board, CCD Board, Switch Board, Panel Board, etc.. Therefore,
well packing will be required when sending them by post or courier.
1. Some sophisticated IC components are mounted on the PCB assembly, hence it is necessary to
pack each PCB assembly with a separate static protecting beg, in order to avoid static
electricity.
2. CCD sensor is the most important component on the CCD Board, hence, CCD sensor must be
covered by a protecting sheet (shown as below) when mailing it, in order to prevent from
scratch.
CCD sensor, covered by a screen
protecting sheet
3. Reliable external packing is also very important when sending the PCB assembly by post, in
that it would avoid unnecessarily lost or damage.
Short of spare parts while repairing a scanner
If you are short of spare parts when you have some scanners waiting to be repaired, it would be
recommended to take the necessary parts from one scanner, so that you may have the as many
as scanners be repaired and sent back to your customer, and left only one or few scanners
waiting for spare parts sending from KYE.
