ESDS information
Electro–static discharge sensitive devices
Components which can be destroyed by electrostatic discharge are individual
components, integrated circuits, or boards, which when handled, tested or
transported, could be destroyed by electrostatic fields or electrostatic dis-
charge. These components are designated as ESDS (ElectroStatic Discharge
Sensitive Devices).

The human body, working area and packing should be well grounded when
handling ESDS components!
Electronic boards should only be touched when absolutely necessary.
Components may only be touched, if
– you are continuously grounded through an ESDS bracelet,
– you are wearing ESDS shoes or ESDS shoe grounding strips in con-
junction with an ESDS floor surface.
Boards may only be placed on conductive surfaces (desk with ESDS sur-
face, conductive ESDS foam rubber, ESDS packing bag, ESDS transport
containers).
Boards may not be brought close to data terminals, monitors or television
sets (a minimum of 10 cm should be kept between the board and the
screen).
Boards may not be brought into contact with materials which can be char-
ged–up and which are highly insulating.
Measuring work may only be carried out on the boards, if
– the measuring equipment is grounded (e.g. via the protective conductor)
or
– for floating measuring equipment, the probe is briefly discharged before
making measurements (e.g. a bare control housing is touched).
