Electrostatically sensitive devices (ESD)
&DXWLRQ
Electronic modules contain electrostatically sensitive devices that can easily be
destroyed if they are incorrectly handled. However, if your work does involve the
handling of such devices, please observe the following information:
♦
Electronics 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 may not be allowed to come into contact with electrically insulating
materials such as plastic foil, insulating table tops or clothing made of synthetic
fibers.
♦
Modules may only be placed on electrically conducting surfaces.
♦
Modules and electronic components should always be packed in electrically
conducting containers (such as metallized plastic boxes or metal canisters)
before being stored or shipped.
♦
If packing containers are used which are not conductive, modules and boards
must first be wrapped in a conducting material. Examples of such materials
include electrically conducting foam rubber or household aluminum foil.
For easy reference, the protective measures necessary when handling electrostatic
sensitive devices are illustrated in the sketches below:
−
a = Conductive flooring
−
d = Anti-static overall
−
b = Anti-static table
−
e = Anti-static chain
−
c = Anti-static footwear
−
f = Grounding connections of cabinets
