2.2 ESD and Handling Precaution
Please note that the LPC3250 OEM Board and QVGA Base Board come without any case/box and all
components are exposed for finger touches – and therefore extra attention must be paid to ESD
(Electro-Static Discharge) precaution.
Make it a habit always to first touch the metal surface of one of the USB or SC/MMC connectors
for a few seconds with both hands before touching any other parts of the boards. That way, you
will have the same electrical potential as the board and therefore minimize the risk for ESD damages.
Never touch directly on the LPC3250 OEM Board and in general as little as possible on the QVGA
Base Board. The push-buttons on the QVGA Base Board have grounded shields to minimize the effect
of ESD.
Note that Embedded Artists does not replace boards that have been damaged by ESD.
Do not exercise excessive pressure on the LCD glass area. That will damage the display. Also, do not
apply pressure on the two flex cables connecting the LCD. These are relatively sensitive and can be
damaged if too much pressure is applied to them.
Note that Embedded Artists does not replace boards where the LCD has been improperly
handled.
