CAUTION
Electrostatically sensitive devices (ESD)
Electronic modules contain electrostatically sensitive devices that can easily be destroyed if they are
improperly handled. However, if your work does involve the handling of such devices, please observe the
following information:
♦ Electronic modules should not be touched unless work has to be carried out on them.
♦ If it is essential for you to touch an electronic module, make sure that your body is electrostatically
discharged beforehand.
♦ Modules must not be allowed to come into contact with electrically insulating materials such as plastic foil,
insulating table tops or clothing made of synthetic fibres.
♦ Modules may only be set down or stored on electrically conducting surfaces.
♦ The soldering tip of soldering devices must be earthed before they are used on modules.
♦ Modules and electronic components should generally be packed in electrically conducting containers (such
as metallized plastic boxes or metal canisters) before being stored or shipped.
♦ If the use of non-conducting packing containers cannot be avoided, modules must be wrapped in a
conducting material before being put into such containers. Examples of such materials include electrically
conducting foam rubber or household aluminium foil.
