Handling instructions for printed circuit
boards and electronic modules
Printed circuit boards and electronic modules 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.

Circuit board unpacking and handling
It is very important that printed circuit boards and other electronic modules are handled
correctly.
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)!
