5 Measurements and Modifications to ESD Modules
• Measurements on modules may only be carried out under the following conditions:
– the measuring equipment is grounded (e.g. via the PE conductor of the power supply
system) or
– when electrically isolated measuring equipment is used, the probe must be discharged
(e.g. by touching the metallic casing of the equipment) before beginning measurements.
• Only grounded soldering irons may be used.
6 Shipping of ESD Modules
Anti-static packing material must always be used for modules and components, e.g. metalized
plastic boxes, metal boxes, etc. for storing and dispatch of modules and components.
If the container itself is not conductive, the modules must be wrapped in a conductive material
such as conductive foam, anti-static plastic bag, aluminum foil or paper. Normal plastic bags or
foils should not be used under any circumstances.
For modules with built-in batteries ensure that the conductive packing does not touch or
short-circuit the battery connections; if necessary cover the connections with insulating tape or
material.
