1.3.4.2 Important Measures to Protect Against Static Charging
► Most plastics can easily become charged and must therefore be kept away from at-risk
components.
► Always ensure that people, the workplace and packaging are safely earthed when handling
electrostatic sensitive components.
1.3.4.3 Handling ESD Modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other
work. If it is necessary, make sure that you do not touch the pins or printed conductors when you
pick up flat modules.
Do not touch components unless
● You are constantly earthed by an ESD wrist strap or
● You are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a
conductive and earthed object immediately before you touch the module (such as unpainted parts
of a switch cabinet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g.
plastic films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD
foam, ESD bag or container).
Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm
away from the screen.
1.3.4.4 Measurements and Modifications to ESD Modules
Measurements of the assemblies may only be taken if
● The measuring device has been grounded (e.g. via protective conductor) or
● The measuring head of the potential-free measuring device has been briefly discharged before
measurement (e.g. touching blank metal control unit housing).
► Always use an earthed soldering iron if you carry out any soldering work.
1.3.4.5 Dispatching ESD Modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags or
metal sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before
packaging. Use conductive foam rubber, ESD bags, domestic aluminum foil or paper, for
example. NEVER use plastic bags or film.
► If the module has integral batteries, ensure that the conductive packaging does not touch or
short-circuit the battery terminals and, if necessary, first cover the terminals with insulating tape
or material.
