2.5 ESD Guidelines
2.5.1 Handling ESD Assemblies
In generally, the following applies: electronic assemblies may only be touched if the work to be
undertaken requires this. Never take hold of printed circuit boards so that you touch the component pins
or conductors.
Only touch components,
If you are wearing an ESD wristband and are therefore connected to ground or
If you are wearing ESD shoes or protective ESD strips on your shoes and are therefore connected
to the ESD ground.
Before touching an electronic assembly, make sure your own body has been discharged. The easiest
way to do this is to simply touch a conductive object - which is connected to ground. This could be
uncoated metal on a switching cabinet, a water pipe etc.
Make sure that the assemblies never touch charged and high-insulated materials, such as plastic
sheets, insulating table plates or covers made of synthetic fibers.
Only place the assembly down on a conductive surface (table with ESD mat, conductive ESD foam
material, ESD packaging bags, ESD transportation containers).
Never put the assemblies near to data display units, monitors or television sets. Keep the assembly at
a minimum distance of > 10 cm to the monitor.
2.5.2 Measuring and Changing ESD Assemblies
The assembly may only be measured, if
The measuring device is connected to ground (e.g. via a protective conductor) or
The measuring head of a potential-free measuring device has been discharged just before
measurement (e.g. by touching the uncoated metal of a control cabinet etc.)
X When soldering, make sure you only use a soldering iron which is connected to ground.
2.5.3 Dispatching ESD Assemblies
X Always keep assemblies and components in conductive packaging (e.g. metallic plastic boxes or
metal tins) and use conductive packaging when dispatching the assemblies.
If the packaging is not conductive, wrap the assemblies in conductive material before packing them.You
can use, for example, conductive rubber foam, ESD bags, aluminum foil or paper but never plastic bags
or plastic sheets.
X When handling assemblies with integrated batteries, make sure that the conductive packaging does
not touch or short circuit the battery connections. We advise that you cover these with insulating tape
or other insulating material.
