The following procedures reduce the possibility of static discharge damage:
• Wearing a wrist strap while handling PCBs.
• Attach the string of the ACC repair tag to the ejector/injector of the printed
circuit board.
• Insert PCBs into approved static shielding bags with repair tags remaining
outside the shielding bag. Do not insert repair tags into static shielding bags.
• Pack/unpack PCBs at a static-safe workbench.
• Transfer boards in a static-shielding bag or non-conductive board container.
• Properly ground storage shelves.
• Properly ground wrist straps worn by personnel while transferring boards to
the storage shelves.
1.1.4. Shipping Boxes
Individually boxed boards must be placed into a larger packing case for
shipment. Board boxes alone do not sufficiently protect against shipping
damage.
