Returning a printed circuit board or an electronic module
to Kongsberg Maritime
If you wish to return a printed circuit board or an electronic module to us – either
operational or defective – certain rules apply.
Prerequisites
For correct and safe handling of printed circuit boards and electronic modules, you will
need a suitable workbench with an approved conductive service mat. This service mat
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.
Sensitive printed circuit boards and electronic modules must always be transported and
stored in protective antistatic packing bags. The circuit boards and modules must not be
transported or stored close to strong electrostatic, electromagnetic or radioactive fields.
Context
Beware of electrostatic discharge (ESD)!
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.
Note
Failure to follow these rules may result in unserviceable circuit boards.
Procedure
1 Place the circuit board to be returned in the same protective antistatic packing
bag as you originally received it in - or in a protective bag of similar electrostatic
discharge (ESD) protection quality.
Note
DO NOT use standard plastic bags, such as commercial bubble wrap.
2 Fill in all the necessary information on the applicable documentation and place
it inside the bag.
3 Seal the bag.
4 Place the circuit board in a suitable carton, and secure it for shipping.
