Ground (earth) your body while disassembling and working on the scanner.
This can be done by touching any metallic part of the scanner.
4. After removing a cover from the scanner, attach
an earthing (ground) lead between the PCA common and earth ground.
Touch all tools to earth ground to remove static charges before using
them on the scanner.
5. After removing any PCA
from the scanner, place it on a conductive foam pad or into its conductive
packaging to prevent ESD damage to any ICs on the PCA. |
