Foreword
ESD information
Caution
!
An electrostatic-sensitive device (ESD) is an individual component, integrated
circuit, or module that can be damaged by electrostatic fields or discharges.
Regulations for handling ESD components:
S
When handling components, make sure that personnel, workplaces, and
packaging are well grounded!
S
Personnel in ESD areas with conductive flooring may only handle electronic
components if:
– They are grounded with an ESD wrist band
– They are wearing ESD shoes or ESD shoe grounding straps
S
Electronic boards should only be touched if absolutely necessary. They must
only be handled on the front panel or, in the case of printed circuit boards, at
the edge.
S
Electronic boards must not come into contact with plastics or items of clothing
containing synthetic fibers.
S
Boards must only be placed on conductive surfaces (work surfaces with ESD
surface, conductive ESD foam, ESD packing bag, ESD transport container).
S
Electronic modules must be kept at a distance from data display equipment,
monitors, and televisions (minimum distance from screen: >10 cm).
S
Measurements must only be taken on boards when:
– The measuring device is grounded (with a protective conductor, for
example).
– The measuring head has been temporarily discharged before
measurements are taken on a floating measuring device (e.g. touching a
bare metal controller housing).
