Note
When you handle electronic circuit boards and modules, 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.
Procedure
1 Prepare a suitable workbench with a conductive service mat.
2 Make sure that you wear a grounded wristband with direct contact with the skin
When you are working on board a vessel, an “approved conductive service mat” is often
far away. As you still need to unpack circuit boards, make sure that you do it in the
instrument room, or at another location where you have a steel deck.
Note
Keep far away from the bridge or any other rooms with wall-to-wall carpets!
If possible, bring a wristband and ground yourself.
3 Lift the circuit board, in its protective antistatic packing bag, out of the transport box.
4 Place it in a stable position on the workbench.
5 Inspect the unit for damage before you open the plastic bag.
6 Do not break the seal to open a printed circuit board or electronics module package
before the item shall to be used.
Important
If the package is returned with the seal broken, we will assume that the content has
been used. You will then be billed accordingly.
7 Assuming all is well, open the bag and remove the unit.
8 Take out and keep the documentation.
You will need the documentation if the circuit board or module shall be returned
to us.
9 Remove any packing and desiccant material that may be inside.
10 Keep the protective antistatic packing bag for future use.
