Circuit board handling and packaging

Circuit boards are delicate items. They may work year after year in an advanced product,
but then fail due to a small spark of static electricity. For this reason, it is very important
that they are properly handled and protected during shipping.
Beware of ESD!
When you handle electronic circuit boards, you must beware of the dangers of
electrostatic discharge (ESD), both to yourself and to the equipment. In order to ensure
safe transport and storage, circuit boards and other electronic units will always be
wrapped in a clear plastic protective bag, and the bag will be sealed. See also section
Electro-Static Discharge (ESD) on page 185.
Unpacking and handling circuit boards
To unpack a circuit board:
• Wherever possible, prepare a suitable workbench. It must have an approved
conductive service mat, and it must be connected directly to a reliable earth point via
its earthing cord. You must wear a wristband in direct contact with the skin, and the
wristband must be connected to the service mat.
• Lift the circuit board, in its protective bag, out of the carton and place it in a stable
position on the a floor/work bench.
• Inspect the unit for damage before you open the plastic bag.
• Do not break the seal to open a circuit board package before the board shall to be
used. If the board package is returned with the seal broken, we will assume that the
content has been used, and we will bill you accordingly.
• Assuming all is well, open the bag and remove the unit.
• Take out and keep the documentation. You will need it if the circuit board shall be
returned to us. Also, remove any packing and desiccant material that may be inside.
• Keep the protective plastic bag for future use.
